Building your diagnostic tool arsenal
No matter the number of tools in your arsenal, if you don’t know when and how to use them, they’re all useless.
By Scott Brown, Technical Editor
Today, a technician can be presented with challenges that may require a wide range of tooling, but it’s knowing which tools and techniques that makes the modern diagnostic technician an asset. Knowledge and skills must come first because you can have the best tools available, but without the knowledge of when and how to effectively apply that tool, you won’t get anywhere. Knowledge is king!
In this article, I’ll break down many of the tools I have first-hand experience with and others some of my colleagues have found to be successful across the following categories:
• Low voltage
• High voltage
• Driveability, ignition, fuel, and emissions
• General servicing
LOW-VOLTAGE ELECTRICAL TOOLS
Low-voltage electrical systems can produce all sorts of faults across almost every vehicle system. With some of today’s vehicles hosting hundreds of modules, a sound electrical system is a top priority, and that starts at the battery.
Battery starting and charging system testing tools should include a trusty DVOM, a variety of test leads, connections, and a battery charger and test device. When I started in this industry,
it was common to see a volt amp tester (VAT) in the workshop. The tool contained a voltmeter, an ammeter, and a carbon pile. Eventually, the carbon pile took a back seat as a small handheld battery tester entered the market (Figure 1).
The advantage here was that battery assessment could be performed on a battery that was not fully charged. While this test is accurate to a degree, it can still provide ambiguity. Having a secondary way to assess a battery through a tried-and-true load test is one method we use in my shop. Additionally, the carbon pile is used to apply a load to a
charging system, so one could quickly observe an alternator’s ability to perform, and moreover, if you find yourself wanting to test the DCDC converter performance on a Hybrid or BEV, the carbon pile can be of great assistance. Parasitic load testing is another test that is always performed in my shop for every battery service to ensure that the battery has every opportunity to live a long life. Performing this test has had its pain points, especially if you’re going to conduct the test properly. What I mean by this is that unless you have a fully accurate low-amp current probe, you will need to get in between the nega-

tive battery post and cable to measure with your DVOM’s ammeter. Doing this without losing vehicle power is generally where the challenge lies. Over the years, we have adopted special cabling adapters that we would be able to connect between the negative post and the cable so we would be able to start and shut down and exit the vehicle, and then move on to inserting our ammeter without losing vehicle power (Figure 2).
Fast forward to today, and we’re now using a new tool called the PPDraw from Power Probe. This is a tool I saw demonstrated during industry week in Las Vegas, and since that time, one of my apprentices purchased one. This tool has completely simplified our test routine and, more importantly, cut down the test time tremendously (Figure 3).
They also have a few complimentary tools that are used to help one identify the parasitic load source as well, and I highly recommend anyone tasked with performing these routines to investigate what these tools can do.
Additionally, I am seeing the lab scope come in handy today when addressing cranking abnormalities. Whenever I hear a vehicle with an initial slow cranking event, I will usually set up a multi-channel scope to have a look at the starter circuit’s internal resistance by monitoring the initial stall current.
Lower stall current with nominal source voltage indicates unwanted circuit resistance. With proper termination verified, the starter motor’s internal resistance can be seen. The orange current trace shows lower than normal in-rush current as compared to a normally performing vehicle (Figure 4).
HIGH-VOLTAGE ELECTRICAL TOOLS
Anyone working on hybrid or BEVs should already possess basic safety skills and understand how to address the high-voltage (HV) system when problems arise. Two essential tools needed for HV side testing are a
Figure 3 — Power Probe PPDRAW
Figure 4 — Picoscope starter motor current comparison
Figure 5 — Pico Technologies Milliohm Tester
Figure 6 — VCM scanner before
capable DVOM with the appropriate level of insulation testing ability and a milliohmeter. The two devices I have in my shop are the Fluke 1587 and the Pico Technology MT03a Milliohmeter and Motor Tester. When you’re faced with an isolation fault, OE test routines will likely have you performing insulation tests on HV circuit devices after the battery pack has been isolated from the rest of the vehicle.
The milliohm meter will typically be used to assess motor stator windings to verify ohmic specification and balance. Keep in mind, today we’re seeing more vehicles equipped with brushless DC motors driving everything from blower motors to fuel pumps, so the Milliohmeter will come in handy when performing tests on these devices. Not only that, but the device also comes in handy when addressing suspected unwanted resistance (especially intermittent) in network communication wiring (Figure 5). I produced a video highlighting the power of the milliohm meter for reference: youtu.be/m06ghtl 8laE?si=Vy05E2lbAzmUCzme.
Additionally, one should possess the appropriate scan tools for addressing EVs. The Autel lineup has an outstanding set of tools that can be leveraged for diagnosis. Additionally, they have a very capable tool that can be deployed to interrogate the BMS of most EVs. This can come in handy when assessing used batteries before they are installed in the vehicle.
DRIVEABILITY, IGNITION, FUEL, AND EMISSIONS TOOLS
The scan tool is my primary go-to device when addressing most driveability complaints. And like any diagnostic tool, the best tool for the job is the one that can deliver the appropriate information needed in a timely manner. So, depending on the vehicle, symptoms, and conditions, I may choose any of the following tools, and some of course would be used together.
VCM scanner - HPTuners - In most driveability situations, I like to use this tool on road tests since it’s always recording, and playback/review is great. The tool allows one to configure, save, and recall display panels to their liking, and since it’s PC-based, it allows me to screenshot and mark up views, streamlining my documentation process (Figures 6 & 7).
Autel Maxisys - This tool is like the Swiss Army knife, meaning that it
is quite versatile for many operations (Figure 8).
Bosch ADS 525x - Our SMS will allow this device to report directly into an open work order streamlining workflow during routine inspections.
Standalone wideband meterMotec PLM - This device is coupled with a tailpipe adapter, allowing us to compare values with the vehicle’s air fuel ratio sensor. Here’s a real-world example:
Figure 7 — VCM scanner after
Figure 8 — Autel Maxisys
Figure 9 — Commanded lambda vs. lambda
Figure 10 — Mityvac FST Pro MV5545
Scan tool data shows a commanded EQ value of 0.993 and a reported lambda value of 0.989 (Figure 9).
If compared to the tailpipe standalone lambda meter, you would see that the actual value is 0.840. This vehicle has a brand new wide-band sensor that was damaged because the PCM’s control over the heater circuit was shorted.
Fuel pressure - Mityvac FST Pro, No. MV5545 - This tool gets less use these days since most vehicles today provide a fuel pressure PID within the scan tool. For the times when you need to measure pressure and volume, even on a return-less system, this tool gets the job done (Figure 10).
Picoscope 4425A - This is a 4-channel scope that comes with all appropriate probes, including voltage, ignition, current, pressure sensors, and more. Like most advanced tools, this tool will take you as far as your knowledge allows. From basic battery starting and charging system tests, as mentioned earlier, relative compression, in-cylinder waveform collection, and multi-cam CMP/CKP relationship testing to network signal analysis and more. In the following example, I am comparing one suspect injector with another and was
Figure 12 — Extech Manometer
Figure 11 — Picoscope Injector current comparison
Figure 14 — AESwave uActivate
Figure 13 — Associated Battery Maintainer
able to see that the suspect injector was physically opening later than normal (Figure 11).
Manometer - This is a tool that is primarily used on vehicles that need to have the crankcase ventilation system verified. Many cars today have sophisticated PCV systems (especially on boosted applications), and when they fail, they can be the source of a variety of engine performance faults (Figure 12).
GENERAL SERVICING
If you’re doing any level of diagnostics, it is imperative to maintain sufficient vehicle power during testing, analysis, and, more importantly, programming and calibration. Our shop has several maintainers (Figure 13).
Inspection camera - Vivida VA-450Another great tool for general service and maintenance is the inspection camera. We use the Vivida VA -450. Back in the day, a mirror and a light were sufficient; today, we have access to digital inspection tools, which come in handy often.
And finally, general electrical system checks of load devices at a power distribution center can be quickly performed by one of the go-to devices I’ve been using for more than a couple of decades. The uActivate from AESwave. com makes for quick work (Figure 14).
For example, you have a vehicle that was towed in, and you want to check the fuel pump circuit. Simply, unplug the relay and insert the tool. Now you have access to timely information and actions you can perform to help you move through your diagnostic processes.

Getting out of the Dark Ages
Shining a light on shop and technician lighting needs.
By Pete Rudloff, Contributing Editor
Let’s face it, lighting is an oft-forgotten but critical part of everything we do. Almost all of us, especially those of us with older, tired eyes, have encountered a time when we needed more light for something we were working on. Even for those with excellent eyesight, you won’t find a technician anywhere in the world who doesn’t value a good service light or have a trusted, favorite flashlight/ headlamp.
Much like the automobile, technician and shop lighting technology has transformed significantly over the last 100+ years, including some meaningful advancements in the past 25 years. Since the early 1900s, incandescent lights were the only option better than a simple kerosene lantern. While it pales

in comparison to current technology, incandescent lights were leaps and bounds ahead of kerosene lanterns. The 1930s saw the adoption of batteryoperated, hand-held work lights; though these could be described as dim on their best day, they were better than nothing.
It has been an incredible advancement in lighting technology over the past 100 years, and LED lighting is the best technology currently available.
SHOP FACILITY LIGHTING
In the 1950s and 60s, many shops began moving from incandescent bulbs towards either fluorescent-type bulbs or high-intensity discharge (HID) bulbs, often referred to as high bay lamps. By the late 1970s, most auto repair shops were using one or the other. Lighting was decent with either, though both had issues with cold temperatures, and HID in particular required a good amount of warming up before they produced a usable light to work with. Fluorescent lights were typically used with inside ceiling heights under 10’, and the HID lights tended to work best when ceilings were 12’-15’ high, or more (Figure 1).
In the early 2000s, we began seeing light-emitting diode (LED) technology that at the time looked promising, but was very expensive. Boasting significant reductions in electricity consumption and huge boosts in lighting output (lumens), LEDs slowly started to find their place. As their popularity grew, the cost to implement LED lighting dropped significantly. By 2020, LED technology had firmly taken its place as the best lighting technology for indoor and outdoor spaces. Offering a huge range of designs, LEDs have become the “Swiss Army Knife” of lighting. You can basically find a design that fits any need for any building, inside or outside. They are brighter, can be fully weatherproof, have better energy efficiency, and can be had for pennies compared to incandescent, fluorescent, or HID lighting.
A few years back, I completed my shop. A 2,400 sq. ft. building, and I didn’t hesitate to outfit it with 20, 8’ long LED light packs, purchased on Amazon for about $20 each. They boast a 15k lumen rating, and, when installed in my 20’ high ceiling workshop, emit so much
light that I tend not to look up! There really is no other, more viable lighting option for a shop than an LED bulb. Specific workspace lighting is also important. Aside from updating to LEDs on the ceiling of workshops, progressive-thinking shops are adding light

certainly could lead them to prejudge a business’s competence before they get a chance to see how great the staff really are. Smart shop owners know this and invest in bright, clean light, inside and outside their facilities (Figure 3).
TECHNICIAN LIGHTING
Good shop lighting is important, but even good shop lighting leaves a lot to be desired for the typical technician who has to work under or inside a car. For a long time, technicians relied on a drop light that was attached to a cord and pulled down from a retractable reel from the ceiling. These worked because we didn’t know any better. Corded droplights had a lot of drawbacks, not the least of which was that they were restricted by how long the electrical cord was.
Other drawbacks included incandescent bulbs that generated a lot of heat, which could inadvertently melt things on a car’s interior. Plus, incan-
descent bulbs are really fragile. Even with a metal cage around them, most bulbs wouldn’t survive a drop from 30” off the ground. Not to mention, dropping an incandescent bulb around an open fuel source, like when replacing a fuel filter, could result in a devastating fire. Corded fluorescent and then LED droplights solved some of the most dangerous drawbacks to having droplights, but generally speaking, there are much better, non-corded solutions for today’s technician.
FLASHLIGHTS
I cut my teeth as a dealership technician in the early 1990s, and back then, there was one name that technicians recognized as better than all others: Maglight. Maglight flashlights were a staple in every technician’s toolbox from the 1970s up through the 1990s. Ranging in sizes, probably the most popular were the aluminum-bodied models that took the “C” size batteries.
Back in my early days, the rechargeable Maglight with a halogen bulb was the holy grail. They were expensive, but any technician who had one was known to take their job seriously, and I had two. Moving forward to today, we’ve seen the flashlight market become extremely competitive, especially with the adoption of super bright, energy-efficient LED bulbs. Flashlights come in all shapes and sizes to fit the needs of any technician. It may even make sense for a technician to own multiple different flashlights. (Figure 4).
HEADLAMPS
Headlamps started to gain popularity in the early 2000s, but were large, clunky, and didn’t have very good battery life. In the past 15 years, we’ve seen these shrink, get lighter, brighter, and, with LED technology, we’ve seen headlamps that can last 6+ hours. This type of light is useful because it frees up both of the technician’s hands, and it’s easy to
p Figure 2 — Magnetic mount and adjustable LED work lights like these are becoming standard equipment in many shops.

point where you need the light because it’s attached to your head. You can find comfortable, lightweight headlamps for well under $100 nowadays. There are so many options available that you’ll have to try a few to see what suits you best.
INSPECTION LIGHTS
Inspection lights are lights with flexible ends that allow you to manipulate them into tighter spaces, sometimes utilizing a fiber optic tube to help with this. I like using inspection lights for peeking inside a wheel to see how much brake life is left. Inspection lights don’t shine as bright as a flashlight, but you can put light on exactly what you need, and for cases like checking brake life, an inspection light works best.
Ultraviolet lights are another type of inspection light. They are really useful when chasing fluid leaks. You can add
fluorescent dye to just about any fluid, and a UV light helps make the dye really pop at the leak source.
LIGHTING TRENDS
I’m starting to see a trend in new ideas for lighting popping up throughout the trade. Lights that are flexible enough to fasten around a wheel well, lighting up the entire well area and all the suspension and brake components. This shows innovation that will be useful for many technicians. Under-lift lighting options are also starting to gain popularity. These are lights that clip onto a loft arm and can be manipulated under the vehicle to shine up at the work area. It is hard to write about lighting for the auto repair industry and not think about how lucky we are to even have the ability to create our own light. It was only in 1879 that Edison invented the
first viable incandescent light bulb. To think, before that, all workshops were lit by gas and kerosene lanterns. I couldn’t imagine working in those conditions. It is amazing to see how far we have come in workshop lighting, and I’m looking forward to seeing what the innovators of the lighting field will come up with next.

Cal-Van Brake Anchor Pin Press
Reviewed by Eric Moore, independent technician in Columbus, Ohio.
Q: How did the tool function as far as saving you time?
A: The Cal-Van Brake Anchor Pin Press really does work exactly like the name says. It is just the right size, plenty stout, and just works. Not having to remove the backing plate or the hub, it fits over the top and lines up nicely.
Q: What kind of setup was involved before using the product?
A: Very little setup was required to use the tool. Take it out of the case and choose whether the additional adapters are needed or not.
Q: How easy was it to use?
A: This tool is very easy to use and pretty self-explanatory in how it functions.
PRODUCT DESCRIPTION
The Brake Anchor Pin Press, No. 70100, from Cal-Van Tools is designed to remove brake anchor pins and bushings on 16-1/2” S-Cam trailers and Tractor Q brake systems. With this tool, there’s no need to remove the hub or dust shields. Designed for use with 1/2” impact wrenches, it has a 10-ton capacity C-frame and can easily remove seized anchor pins. For more information, visit VehicleServicePros.com/55281332
This
Q: How was its packaging? Did it come with any accessories?
A: The brake anchor pin press comes in a labeled blow molded case. It has an additional extension and centering adapter for removal. The press itself is a forged C-shape press body with a screw press sized for the S-cam busings on most trailers and air brake systems we see.
Q: Was there a manual included? If so, did you use the manual, and was the manual easy to understand?
A: No manual is included. Use of the tool is pretty intuitive.
Q: What features did you like?
A: I feel like this is a nicely forged tool; strong materials were used. It’s built to be used with an impact.
Q: What types of jobs/repairs did you use this tool for?
A: We used it specifically for what it is designed for — the removal of S-cam bushings and brake pin anchors, and it works well. Anyone who has replaced S-cam bushings knows that there are easy ones and ones that don’t play nice. This tool handled every one we used it on simply, smoothly, and relatively quickly. We did have to get a couple of bushings warmed up for them to press out easier, but even if we hadn’t, the tool was moving them.
Q: Have you used a previous version of this tool? If so, what are some new features compared to the old version?
A: I know there are other types and brands of S-cam presses, but I have not used them before. I have used other types of press tools similar to this for different situations or repairs. Most comparable would be a ball joint press or universal joint press. I think the only difference is that this tool would be an extension. Overall, it’s similarly constructed, just sized appropriately.
Q: On a scale of 1 to 10, how would you rate this tool overall? Why?
A: That’s going to be a challenge. Not everyone needs this specialty tool. However, if you do heavy duty brake repair, this is a smart investment for making a not-so-fun repair just a bit more manageable. Trying to fit this into a scale… I’d have to say if you’ll use it, it’s an easy eight.

The tower is easily movable and locks securely into position, making for accurate placement.
Q: How was its packaging? Did it come with any accessories?
A: The target storage and access are well thought out and organized. Each piece is coded into the system with a unique identifier, making it virtually impossible to use the wrong target or cone.
Q: Did you use the manual, and was it easy to understand?
A: Hunter does an excellent job of outlining the step-by-step process both on Ultimate ADAS. The instructions are clear, easy to understand, and, to ensure accuracy, will not allow any process to continue until all steps are done correctly.
Q: What features did you like?
A: I love the fact that Ultimate ADAS takes a lot of the manual and timeconsuming steps out of the calibration process. This also ensures the utmost accuracy in the calibrations being performed, which is critical for proper system function and passenger safety.
Q: What types of jobs/repairs did you use this tool for?
A: I used this for a static calibration of both the forward-looking radar sensor and front outside view camera on a 2024 Toyota Camry SE.
Q: On a scale of 1 to 10, how would you rate this tool overall? Why?
A: A 10 as I stated earlier, this is the most user-friendly ADAS offering I have used. Ultimate ADAS makes the process easier and more automated, which allows the shop and technician to be more efficient and profitable.

ProMAXX Tool 900 Series Air Hammer-Powered Fuel Injector Puller ProKits
Q & A with Jeff Del Rossa,
general manager of ProMAXX Tool.
Q: What makes this product innovative?
A: Direct fuel injection has become the predominant way of delivering fuel efficiently, and most engines now use steel injectors in aluminum cylinder heads. Those unlike metals create corrosion inside the injector cavity. Fleet and commercial vehicles also build heavy carbon because they often idle instead of shutting off. The combination makes injectors very difficult to remove. The innovation behind this tool was targeting the technician’s inability to remove injectors in a timely and productive way.
Q: What was the inspiration behind creating this product?
A: Technicians were spending 15 to 17 hours removing cylinder heads just to free a seized injector on Power Stroke and Duramax engines. We wanted to eliminate that. With this tool, you can get a stuck injector out in under 15 minutes without removing anything else. The ROI and time savings drove the innovation.
Q: How will this product improve the lives of technicians and shop owners?
A: It drives profitability and predictability. If they get something done quicker, they can get to other jobs faster, and the overall shop is more productive. Customers get their vehicles back sooner. There’s nothing more rewarding for a technician than delivering a fleet vehicle that’s an asset.
Q: What has been the feedback from technicians who’ve purchased this tool?
A: Outstanding. We had customers in Utah and in Greensburg, Pennsylvania, who had stuck injectors with no solution. They were facing 17 to 19 hours of work. They
bought the tool and removed the injectors within 45 minutes. That saves days of labor and the cost of gaskets and singleuse fasteners you have to replace when removing parts. It all adds up, and this eliminated that entire burden.
Q: Anything else our readers should know?
A: Traditional methods still work in some cases, but modern engines are more challenging. The harmonic vibration and pulling power of a tool that can oscillate at 6,000 blows per minute cannot be replicated manually. This gives technicians another option in their arsenal. With technicians becoming harder to find and the technical demands rising, we need ways to make them more productive. That has been the driving force behind my vision.

Make it Kawasaki green
This technician made his dream of owning a Kawasakigreen Snap-on toolbox come true, and now, he’s working toward his next goal — a “Mr. Big” box.
By Emily Markham, Editor
Chris Biediger has worked as a professional technician for 11 years. Though it was at age 15 that he began working on his own vehicle, his interest in how things work and making repairs started long before
“As a kid, I would take my Xbox apart and try to repair it and take remote control cars apart,” Biediger says. “So, when I was in college, I was like, ‘You know what? I don’t really like sitting in a classroom,’ so I got a job at a Toyota dealer … and haven’t looked back.”
Now, as the shop foreman/lead technician at Hill Country Yota Works in New Braunfels, Texas, he is an ASEcertified Master Technician who’s on track to get his L1, L3, and L4 certifications early next year. Though his shop works on only Toyota and Lexus vehicles, they do “anything and everything,”

Location: New Braunfels, Texas
meaning Biediger has amassed quite the collection of tools and equipment.
WORKING HIS WAY UP
When Biediger started his career, many of his fellow technicians had Snap-on toolboxes, and he wanted one too, so he set that as his goal. He started out with a few different Craftsman toolboxes and worked his way up to his current setup.
Now, the shop foreman has a 72” triple bay Master Series from Snap-on with a hutch and a side locker. In addition to his main toolbox, he also has a Snap-on EPIQ roll cart and the Juic’d Box from Sunex Tools.
Biediger has also added a few customizations to make his toolbox his own, such as the LED lighting he ran on the inside to give himself a green backlight, and in his locker, he drilled a hole, clear-coated it, and installed a grommet to transform it into a power locker — this was before power lockers were available.
Though arguably, the most important customization is the color of the box.
“It’s green with black trim, a very bright Kawasaki green,” Biediger says. “I’ve loved that green since I was six years old, when I got my first Kawasaki.”
However, when it comes to the setup of the toolbox, he notes that the hutch is his favorite part.
“This is my first box with a hutch,” he says, “and ever since owning it, I’d never own a toolbox without one again. I keep my computer in there, my workstation, all my tickets, my scan tool—it’s just really handy to have.”
MIX N’ MATCH ORGANIZATION
To keep his setup organized, Biediger utilizes a mix of organization tools from companies like Ernst Manufacturing, Alien Space Saver, and VIM Tools.
“You kind of have a mix of what fits when you configure a bunch of stuff into a small area,” he explains. “You can use a bunch of widgets, but then you might need a skinny [VIM] Magrail to fit something where a widget won’t fit. You kind of have to mix and match.”
Looking ahead, Biediger says he would like to get a “Mr. Big” setup from Snap-on or at least something similar to that size. For now, as with earlier in his career, the shop foreman is content to work his way up to that “EPIQ” box.
Biediger added LEDs inside his box to create a green backlight.

DIAGNOSTIC PROCESS
Technician-induced diagnostic dilemmas
Blindly approaching a fault is like jumping into an empty pool ... you may quickly get to the bottom of it, but it’s probably going to hurt.
By Chris Farley
Irecently encountered two vehicles with technician-induced problems that I believe offer some valuable lessons. Whether we caused the problem or we’re there to diagnose it, rushing and jumping to conclusions often costs us more time in the end.
CASE STUDY 1: 2013 FORD FOCUS
The customer brought in a 2013 Ford Focus for an intermittent no-crank condition.
My usual diagnostic routine is a pre-scan, a quick visual inspection, and an interview with either the shop owner I’m called to assist or the vehicle owner. But as usual, I got only part of the story, even after thorough questioning. I’ll never understand why this happens.
The shop tested the car and didn’t find anything wrong, so it returned the vehicle to the customer. A week later, the vehicle returned to the shop on the hook of a tow truck. The customer stated that the vehicle had refused to start a few times, and this time it had died on the road. The technician at the shop approached the vehicle, and it started right up. The tech believed the starter must be the culprit. This is not a logical direction to head in for a vehicle that suddenly died on the road.
The shop owner told me they installed a starter, lowered the vehicle to verify it started, and then raised the vehicle to install the underbody shield.
Figure 1 This prescan from my Snap-on Zeus+ shows which modules are communicating. But more importantly, it also shows the ones that are missing.
They then lowered the vehicle, and it again failed to start. They tried to scan the vehicle and found it would not communicate. They decided to push the car out and give me a call.
JUMPING THE GUN
I connected my Snap-on Zeus+ scan tool, and the first thing I noticed was that the vehicle did not auto-identify with the scanner. I manually selected the vehicle and reestablished communication with some of the onboard modules. Now, this is where I’m guilty of having jumped the gun. Since I received the call, all I could think of was the common fault for the symptom that these vehicles experience, a faulty transmission control module (TCM).
Sometimes we need to be reminded of why we have a diagnostic process, and we need to be humbled when we get lazy or ignore it. Although I followed my process, I wasn’t focused because I had
already convinced myself the problem was a failed TCM before I even connected my scanner.
It was a rainy day, and I was in a parking lot. But in my head, I believed all I had to do was unplug the TCM and I’d see vehicle communication return. So, I laid down in the rain and unplugged the TCM, but communication had not returned. For the rest of the day, all I had to show for my effort was wet clothes. Now that my bubble had burst, I got to kick myself and regroup. I went back to my process and I reviewed my scan report (Figure 1). I noticed that the power steering control module (PSCM), the powertrain control module (PCM), and the transmission control module (TCM) are the only modules missing from the bus. At this point, I reviewed the system wiring diagrams, and since I already had the TCM unplugged, I started my testing there. I tested to verify the TCM had everything it needed
Figure 2
This is the CAN bus waveform when testing at the DLC with my Snap-on Zeus+.
to communicate (voltage supply, ground supply, and communication signals coming in). The only issue I noted was the signal from the high-speed CAN bus low (Figure 2).
THE SECOND APPROACH
My next step was to install my AESWave LineSpi breakout box. I connected the Snap-on scope (Zeus+) and saw the same high-speed CAN low pattern, so then I performed a resistance check on the high-speed CAN network. This test checked the integrity of the circuit and offered me direction.
To perform this test, I turned the key off (so the network isn’t active) and connected my Snap-on DMMacross high-speed CAN+ and CAN-. You should anticipate a 60-ohm reading displayed. However, that is not the reading we were getting here, which tells us there was an incomplete circuit and one resistor was bypassed (Figure 3). I then retraced my steps to decide on which direction we should go:
• The scan report showed that the PCM, TCM, and PSCM were offline.
• A resistance test proved a circuit was open in the high-speed CAN network.
A review of the CAN system topology I sourced for this vehicle from ALLDATA showed the terminating resistors for this network are located in the body control module (BCM) and the PCM (Figure 4). But of those two, only the PCM failed to communicate.
I looked at the CAN bus network diagram (Figure 5). The communication wires pass through connector C238 to splices S109 and S110. From there, the circuit heads toward the ABS module and to connector C140. The ABS module was communicating, so I realized wiring integrity was good up to that point.
The next best place to check our signal is connector C140, which is located alongside the battery. I’ve accessed the high-speed CAN- wiring at pins 3 and 4 with my pierce probes from AESWave (Figure 6). The circuit comes through pin 3 to splice S112, which splits the circuit (to the PSCM and back through C140 pin 4/out to the PCM and TCM).
I performed another resistance test at connector C140 (pins 2 and 3) and measured 120 ohms, but pins 4 and 5 displayed an open circuit. This confirmed the fault was between the two chosen test points.
I jumped pins 3 and 4; communication returned, and I could talk to all
Figure 3 — Resistance test being performed (using my AESWave LineSPI breakout box and Snap-on DMM at the DLC) of the CAN bus.

DIAGNOSTIC PROCESS
modules. I then knew I would find my circuit issue between S112 and C140.
A STEP IN THE RIGHT DIRECTION
To access that section of the wiring, I removed the battery, covers, and tray. Once they were removed, I saw a shiny new transmission mount looking at me. The wiring harness comes out of C140 and goes along this mount before S112. I disconnected C140 and tried to move the harness to gain access for testing, but it was pinched under the mount.
I questioned the shop owner about the new mount. Suddenly, his memory came back, and he told me he had replaced the mount after he confirmed the starter was working (I’ll never understand why it is so difficult to get the whole story up front).
After removing the bracket, I freed the harness and removed the conduit from the harness (Figure 7). This is the extent of the damage (Figure 8). With only a slight tug on the wires individually, two of the wires instantly pulled apart. The shop let me repair the wiring, which allowed me to test the vehicle again after repairs and confirm everything was working properly at that time. I add the “at that time” reference because I know their repair caused this no-start issue, but I don’t think the starter caused the previous issue of the vehicle “died while driving.” We may never know the root cause of this vehicle’s stalling issue, but time will tell.
CASE STUDY 2: 2021 JEEP GRAND CHEROKEE - MIL AFTER REAREND COLLISION
I got a call to look at a 2021 Jeep Grand Cherokee with multiple indicators illuminated and a handful of DTCs. It was hit hard in the right rear of the vehicle, and the shop had already replaced a physically damaged module in that area. But when I got to the vehicle, it seemed
all the original faults remained.
IF YOU CAN’T STAND THE HEAT, STAY OUT OF THE KITCHEN
The shop owner told me he called another mobile guy first, and when he saw all the codes (63 to be exact), he turned the job down. When I asked about the replaced module, all he could tell me was that it was behind the right rear interior panel. There are multiple
modules in that location, but they couldn’t be any more descriptive. And of course, they threw out all the old parts. The good news is the odometer was flashing (for those of you who haven’t seen that yet, it means a module in the network needs a proxy-alignment/ configuration). This is a procedure that transfers the vehicle configuration from the BCM into the new module that was installed.
Figure 6 Connector C140 is a perfect spot to divide the circuit to isolate the location of the fault.

DIAGNOSTIC PROCESS
I connected the factory interface (Micropod3) to the vehicle and ran the proxy procedure. The scan tool alerted me that the power liftgate module wasn’t aligned, so now I knew which module was replaced. I performed the procedure, and I cleared the DTCs. I was then left with only seven remaining DTCs (four for rear parking sensors shorted to ground, two for rear radar blind spot circuits open, and one for private CAN network in the central ADAS decision module (CADM)). In a situation like this, I typically choose one code and chase only that one DTC’s root-cause fault. In this case, I chose the rear radar module, a circuit open (C00C4-13).
First, I asked the shop to remove the bumper so I could gain access to the wiring and modules. In factory service information, the set conditions for this DTC are as follows: “The CADM detects a power supply circuit for the left-rear mid-range radar.” A check of the OEM wiring diagram shows voltage coming in through connector XY510A pin 10 (beige/red wire) (Figure 9)
The connector is on the passenger side of the bumper and has plastic covers over both sides, making it nearly impossible to see the colors of the wires. When I removed the covers
from the vehicle side of the harness, I found voltage available at pin 10, but no voltage available at the radar unit. I then removed the cover from the harness on the bumper side, and I found no wire in that connector cavity. The wires that are present did not match the colors indicated in the wiring diagram.
I had another conversation with the shop owner, and he confirmed he had replaced the bumper harness. I decided to inspect the parking sensor wiring and found it was routed through connector XY511A (which is the connector on the driver’s side of the same bumper harness) (Figure 10). I removed the covers
from connector XY511A to inspect the wiring. A beige/red wire at pin 10 on the bumper side of the connector was mated to an empty cavity in the vehicle side of the harness. I wouldn’t have guessed this from the start, but this was a case of the bumper harness having matching connectors on both sides. This allowed it to fit (with all the connectors going across the bumper, for parking sensors) with the wire in either position. Strangely enough, there were no fitment issues, and the only way you could tell there was a difference was if you looked at the terminals in the connectors. A quick swap of the harness, clearing the DTCs, and we had a functioning parking and radar system with a clean post-scan.
Both case studies were shop-inflicted issues that could happen to any of us when rushing to complete a job. Whether it is attempting to drive efficiency up or the pressure we get from impatient customers to get their car back, spending a few extra minutes on either of these jobs would have prevented these issues. They also show how following a diagnostic process and not jumping the gun saves time in the end, even if you are up against 63 DTCs!
Figure 9 — The radar wiring diagram found in the OEM factory service information shows the voltage coming in on pin 10 of the connector.

It’s impossible to scroll through your social feed, watch the news, or browse the internet without artificial intelligence (AI) creeping into the conversation. And for the most part, the headlines about AI seem grim. Some recent “for instances” include:
• FOX Business: Layoffs in October hit highest level for month in 22 years as companies cite cost-cutting, AI
• CNBC: AI-washing and the massive layoffs hitting the economy
• Variety: Rise of the AI job-killing machines
• The New York Times: IBM to cut thousands of workers amid AI boom Reading enough headlines might give you an uneasy feeling that something eerily close to the Terminator film franchise is afoot. Are we stuck in a time loop? Is Arnold going to visit us from the future to save us from ultrasmart machines set to systematically wipe out humanity?
Of course (fingers crossed) not. But let’s not discount the fact that AI is having a very real impact on the business workforce right now. Writing, computer programming, accounting, research, and even acting seem to be the frontline casualties of the AI surge.
But what about auto repair? Are AI robots going to start wrenching on cars?
Probably not.
THOUGHTS ON AI IN THE AUTO INDUSTRY
Some people at the top of the automotive food chain tend to agree that auto repair is, and will remain, in high demand. Ford’s CEO, Jim Farley, has been very vocal lately about the dwindling number of skilled craftsmen in
Is it possible that AI will handle automotive repairs in the future?
the workforce. For all the talk about how AI will wipe out white collar jobs, he believes too little attention is being paid to skilled crafts like HVAC, plumbing, construction, and, of course, auto repair.
In a LinkedIn post on June 2025, Farley highlighted the fact that the US needs 600,000 more manufacturing workers, 500,000 construction workers, and 400,000 automotive technicians.
“Right now, the problems we’re trying to solve are pretty practical. I need 6,000 technicians in my dealerships on Monday morning,” he says.
Another respected voice in the automotive industry agrees.
Regarding AI’s impact on automotive repair, Haakan Light, the manager of training and development at TOPDON U.S. says, “The future of AI in auto repair isn’t one of human replacement, but rather one of collaboration. It’s simply like every other diagnostic tool in the toolbox. You must combine human intuition and ‘gut feelings’ with AI’s complex computation power in order to understand its limitations and maximize its capabilities.” Light,
who traverses the country training auto technicians, believes AI is a mixed bag of opportunity.
“I already see the front office embracing AI more so than the shop itself. Answering phones, helping with accounting, and setting appointments offer limited risk and have the potential to streamline front office operations,” he notes. “But when we get into the technical operations of the repair shop, there’s some danger in relying wholly on AI technology.”
AI MISTAKES IN AUTO REPAIR
One of the “for instances” Light offers up is when he used a premium subscription, which taps into more advanced AI models. He wanted to see if it could correctly diagnose and provide a workable solution for a mechanical issue on a vehicle he was repairing.
“I fed the AI model a bunch of information about the problem I was experiencing,” he says. “As a professional with a wide amount of experience and training and deep subject-matter knowledge, I looked at what AI spit out and knew the solution couldn’t be accurate.”

In fact, Light sent AI back to the drawing board by telling it, “Your analysis is backwards. Lambda values above 1.0 are lean. Lambda values below 1.0 are rich. Please recalculate your analysis.”
AI responded with, “You’re absolutely right – my bad. Reworking the snapshot with that in mind.”
The fact that AI responded back with “my bad” is, in and of itself, quite hilarious (Figure 1). But, as humorous as the response may be, AI still made a fundamentally inaccurate assertion and analysis based on the initial inputs. But it was Light’s experience that coursecorrected the solution. By leaning on his experience and working through the specific issue with AI, the fault turned out to be a drivability-related issue for fault code P0131: “02 sensor circuit, bank 1, sensor 1, - low voltage.”

statistical probability. But someone still has to roll up their sleeves and put in the elbow grease.”
In a separate case, a customer approached Light’s colleague, a professional auto diagnostic technician, with all the reasons why his engine light was on – based on a ChatGPT query, of course. While the issues identified by ChatGPT were plausible causes for the engine light being on, only additional tests could prove which one of the issues it was – or if any of them were even valid.
Which, by the way, they weren’t.
Turns out the problem was a mundane and simple vacuum leak. A solution that didn’t even make his customer’s ChatGPT list.
“No matter what the AI model computes or spits out, testing is still required to prove what the problem is,” Light adds. “Sure, AI can help identify tactical problems and shorten the path from issue to repair based purely on
That’s because automotive repair isn’t just an intellectual exercise. By nature, it’s very physical. Working on a vehicle is not a repetitive task, like bolting screws on a chassis assembly line. It requires a high level of critical thinking, human intuition, and manual labor. Something that robotic AI labor can’t perform.
THE FUTURE OF AI IN THE SHOP
Where Light finds AI to be most useful regarding automotive repair, is in the aggregation and analysis of data. Feeding AI data and asking it to look for patterns is something it can do very well – and exposes a technician to less risk - while augmenting efficiency.
For example, AI helped Light spot a pattern from multiple diagnostic scans on the same vehicle. The synthesized AI report concluded that “the Gateway [19] retains all network fault memory and is likely the root hub of communication failure.” The recommended next
steps, which, this time, turned out to be helpful in isolating the problem, included checking network instability, power-supply issue, ground/reference drop, and gateway overload. According to Light, the failure on the vehicle was in fact a defective J533 Gateway Control Unit.
“Let’s say you upload a number of SAE PDFs, you can ask AI a specific question related to those documents that can lead to a more accurate response,” Light says. “You can also ask AI to ‘water it down’ or summarize the documents so you can cut through the clutter and get to the more conclusive and critical parts of the documents.”
Light also suggests that AI can be used as a more advanced search engine. Since some AI models are connected to specific automotive resources, like technical service bulletins, AI may be better able to help find that information faster than a traditional browser search.
AI IS JUST ANOTHER TOOL
Light’s understanding and experience with AI is helping TOPDON roll out
NEW TECHNOLOGY
the company’s new TopFix AI scan tool. To explain how this new tool will work, Light gives the example of working on European cars. “Mechanics who repair European makes usually don’t get enough information from the manufacturer about what a trouble code is, or how it’s being defined,” Light says. “TopFix AI can be used to search for extended definitions and additional information on a fault code directly from the OEM. “For example, if 5,000 technicians are asking the same questions about a specific code, TopFix AI can aggregate the data and provide a higher level of insight into the specific system or component that’s most often associated with the trouble code. It’ll behave similarly to a more sophisticated search engine. The difference is that it will be available through the scan tool itself. That is a game changer.”
TopFix AI, which was introduced at this year’s SEMA Show, will give techs struggling with a repair additional ideas or pathways to start. It can find a bulletin, for example, that’s tied to the specific fault code in question (Figure 2). While it’s not designed to replace a technician’s ability to solve problems, it can give immediate information or feedback that can streamline repairs instead of spending time on exhaustive searches online about the problem.
But what separates TopFix AI in the marketplace is the fact that it’s been developed by automotive professionals, not software engineers. So, it’s specifically designed to help auto technicians who struggle with common repairs, not just perform random, pre-programmed functions.
Light’s hope for AI in the automotive repair space is that it will become a productivity or efficiency tool. “As a trainer, we want to teach everybody how to use their tools effectively, he notes. “Whether we’re talking about a
battery tester or charger or scan tool, AI should be seen as just another tool in the toolbox.”
YOU WON’T BE REPLACED BY AI
Automotive repair is unpredictable, at best. While vehicles over the years share common engineering, transmissions, fuel, braking, exhaust, and suspension systems, they can be wildly different between vehicle makes and models. There are literally hundreds of thousands of complex components and parts to each vehicle. The idea of asking AI to accurately diagnose and properly identify the solution to an engine light warning is highly unpredictable.
Where Light sees AI as most likely to help the automotive tech is in creating greater efficiency.
“If you can ask AI to retrieve the vehicle manufacturer wiring diagram for a manifold air pressure sensor and have it downloaded directly to your phone,” he explains,” that can have 10 times the value to augment productivity and day-to-day workflow.”
It would be great if AI could tackle diagnostic repairs more efficiently. But maintenance and repair are still going to fill the bays more than specialized diagnostics services. If we can simply ask AI to log into a subscription account to parse service information and retrieve an accurate wiring diagram, Light believes it would be a massive time saver.
While AI can touch many aspects of automotive repair, the nuanced and hands-on nature of the job, not to mention the complex problems presented by vehicles with little to no computerized systems, will remain an essential part of the auto repair process.
“As I see it now, AI is not going to replace the person who is technically trained and who practices every day using their tools,” Light adds. “As I
cross the country training technicians, one of the primary concepts I teach is critical thinking. That’s because modern vehicles are highly complex systems of mechanical parts, sensors, electronic components, and software. Nothing can replace that human intuition that comes from observing the sound of an engine knock or the burning smell of a slipping belt.”
So, what’s the takeaway? If you’re an auto technician, or plan to become one, rest assured that it’ll be years…if ever… before AI robots can replace you under the hood or beneath a lifted car.
Now, whether Arnold’s going to jump through a time loop and take your job decades down the road? Well, we’ll just leave that storytelling to Hollywood.

LEARNING TOOLS
Finding the limitations of your tools
By understanding your tools’ limits, you’ll be better able to wield them to your advantage.
By Brandon Steckler
Every tool you own has a limitation. It’s easy to see with something like a ratchet—a short one doesn’t provide enough leverage for high torque, while a long one makes it hard to feel low torque accurately. The same holds true for diagnostic equipment. Contrary to popular belief, it doesn’t matter how much or how little you spend on diagnostic tools — every single
one has its limitations. And if you don’t know what those limitations are — what the tool can and cannot do — you’re in for a world of hurt. You’ll end up relying on that tool for information, and even if you understand what you’re looking for, if the tool can’t accurately show what’s happening within a component, system, or circuit, you’ll be working with bad information.
TOOLS AS EXTENSIONS OF YOUR MIND
One thing I want to point out is that tools, if you really think about them, become an extension of our mind. They allow us to behave like the scientists we are. Once we understand how individual components work, we can see how they come together as a system to accomplish a goal. From there, we can carry

out tests to determine whether a function was performed correctly, either by a single component or by the system as a whole.
We form hypotheses based on our fundamental knowledge of what should be happening, and it’s our tools that let us test those hypotheses and reach diagnostic conclusions — whether something’s broken or everything’s fine. The tests we perform give us the answers we’re looking for. But that brings us back to the point about limitations: if we don’t know what a tool can’t do, we may rely on it for information that isn’t correct. And even if we know what we’re doing, bad information still leads to bad diagnostic decisions.
PUSHING TOOLS TO THEIR LIMITS
We’ll be testing tool limitations based on what I’ve learned over the course of my career about implementing tools. I’ll be carrying out some tests — essentially taking these tools for a test drive — to see what they can do and, more importantly, what they can’t. By pushing them to their limits, we can better understand what’s really happening within the components and circuits we’re testing.
We’ll use several tools — a test light,
a digital volt-ohm meter (DVOM), and a lab scope. Each of these offers valuable information when used correctly, but each also has limitations. I want to show you what those limitations are and how to identify them for yourself.
This matters because if you’ve ever watched a truly skilled diagnostician, it looks effortless — almost like a game. That’s because they know how to implement their tools the right way, using them as extensions of their mind to test hypotheses and make accurate diagnostic decisions quickly. But when a diagnostician doesn’t understand what their tools can and can’t do, that’s when bad decisions happen.
THE TEST LIGHT
Let’s take a look at a functioning light bulb circuit. It’s simple — a switch to turn the circuit on and off with no other resistance in place besides the light bulb itself. What we have here is essentially a switched resistor; we can switch the resistor in or out of the circuit. When the resistor is switched off, it acts like a fusible link, bridging the gap in the circuit board.
Now, the light bulb’s resistance measures about 7 ohms. Check out
Figure 1 to see the change in brilliance of the bulb as I switch in the resistor. You can see a slight change in brightness, but it’s so small that if you blink, you might miss it. The bulb still appears nearly the same, even though we’ve added resistance.
In this circuit, we can see the bulb illuminate to a certain brightness. But our eyes can’t measure that brightness precisely. When we added resistance nearly double the bulb’s own value, the change in brilliance was minimal because the circuit already has relatively high resistance.
The point is that the light bulb here can represent an incandescent test light or a noid light we might use on a fuel injector circuit. The bulb illuminates, so we assume the circuit is healthy. But as this test shows, even when resistance doubles, the light still appears the same — potentially misleading a technician into thinking the circuit is fine when it’s not.
THE DIGITAL MULTIMETER
Let’s take this a step further and apply the same fault using a different tool. This time, we’ll use an ohmmeter to measure the resistance of both the light bulb and
Figure 1 — Not much change is visible in the bulb’s brilliance. This is the limitation of leveraging the test light. Photo courtesy of Brandon Steckler
LEARNING TOOLS
the added resistor. Remember that the light bulb alone measures about 7 ohms. When we switch the resistor into the circuit, the total resistance increases by nearly 50 percent (Figure 2).
You can see that the ohmmeter clearly shows the issue, while the test light did not. The light still appeared nearly the same even though resistance doubled. The ohmmeter, however, revealed an increase in resistance, pointing to a fault in the circuit. It doesn’t tell us where the fault is — that would require isolating components — but it does confirm a
resistance problem.
Now, what if that same fault existed in a circuit that functioned, but not well — a more dynamic circuit that switches on and off rapidly? In that case, an ohmmeter wouldn’t be the right tool.
Looking back at our circuit, the red lead measures the voltage feed, and the white lead measures the ground side, or injector driver control. Since this is a ground-side driven injector, there’s no voltage when the circuit is inactive. When we turn it on, the DVOM shows
nearly source voltage — about 12V. Using the DVOM’s Min/Max mode, we see a highest reading of 12.12V and a lowest just under 12V, less than a 200 millivolt difference.
You might wonder, ‘How can that be?’ The capture rate of the DVOM is simply too slow to register the quick changes happening in the injector circuit. The ohmmeter could only show that a problem existed, not where. To pinpoint the fault, we’d have to open the circuit and test at different points. But with a more dynamic test, like a voltage drop test, we can allow current to flow and measure voltage across the circuit in real time. This method reveals faults without disassembly because the circuit is being tested dynamically.
Now let’s look at a circuit that operates dynamically and changes state very quickly. To better capture what’s happening, we’ll use a different function on the DVOM. By pressing the frequency button, we can see it reads 5 Hz — meaning the injector is firing five times per second (Figure 3).
So, let’s do a quick recap. Even though the DVOM is a step up from the simple light bulb brilliance test — and the ohmmeter left us guessing because we’d need to take the circuit apart to
Figure 3 — The meter is displaying a 5 Hz signal, indicating that the injector is being driven five times in one second of elapsed time. Photo courtesy of Brandon Steckler
Figure 2 — Although this low current circuit didn’t show a major change in bulb brilliance, the ohmmeter shows a nearly 50 percent increase.

find the fault—voltage drop testing gave us more insight by allowing current to flow dynamically. However, on this fast-switching injector control circuit, the DVOM’s update rate was too slow to accurately capture voltage changes in voltage mode.
By using the frequency function, we can at least see how quickly those injector pulses occur. But remember, the goal here is understanding tool limitations. While the frequency mode shows pulse rate, it still can’t identify whether a fault exists in the circuit. That’s where a lab scope becomes essential.
THE LAB SCOPE
Let's replace our meter leads with the scope leads, switch in our added resistance and review the first waveform
capture from the fuel injector. Remember, the injector was functioning normally until we introduced unwanted resistance.
Looking at Figure 4, you can see the circuit being sampled with the lab scope in the red outlined box. An ‘X’ marks before and after the resistance was switched in. On the left, the injector operated normally; on the right, we introduced additional resistance. This shows exactly what the DVOM showed us — a full injector cycle lasting about 200 milliseconds, which equates to roughly five injector cycles per second, matching the DVOM’s frequency reading.
But now let’s focus on what the DVOM didn’t show us. Looking closely at the voltage drop, the normal injector
waveform shows about a 120-millivolt drop across the injector (Figure 4 – lefthand side), which is completely normal. However, once the added resistance was introduced on the ground control side, the voltage drop spiked to nearly 1.7 volts (Figure 4 – right-hand side), which is a significant change that neither the light bulb test, the DVOM in voltage mode, nor the DVOM’s frequency reading revealed.
Those were the limitations of those tools. The lab scope, however, showed us exactly what we needed to see.
A LAB SCOPE’S LIMITATIONS
As you can see, the lab scope covers nearly everything we’ve discussed so far. It lets us see available voltage, voltage drop across the injector, injector
LEARNING TOOLS
pulse frequency, and any corresponding voltage drop occurring away from the injector. That pretty much gives us everything we need to see.
However, we have to remember that every tool has its limitations. Even what many consider the best tool in an automotive technician’s arsenal, the multi-channel lab scope, has its own. The lab scope relies on its high sampling rate — how often it takes a measurement and plots a data point. That overall sample rate is shared among all active channels, so the more channels you use, the fewer samples each channel receives. Likewise, the more time you display on screen, the more those data points must be spread out to cover the full time base.
To demonstrate this, we’ll use our simulator board to capture a crankshaft position sensor signal. I’ll capture this in two aspects — one correctly and the other incorrectly — and we’ll take a closer look at the differences.
In the first capture, the scope is set to 5 seconds per division, so about a 50-second sweep. The scope handles this easily, and when we zoom in, the waveform appears as a clean, healthy square wave transitioning between 5V and 0V ( Figure 5), exactly as it should.
Figure 4 — For the first half of the capture, the circuit operates normally. In the second half, a 5-ohm resistor was switched into the circuit. When zooming in, the voltage drop created by the resistance is clearly visible. Photo courtesy of Brandon Steckler
Figure 5 — A crankshaft position sensor (CKP) signal is being captured from an idling engine. With 50 seconds of capture time, there is more than sufficient sample rate to accurately display the sensor’s output. Photo courtesy of Brandon Steckler
Figure 6 — Pushing the scope beyond its limits gives an insufficient sample rate. As a result, the waveform peaks appear triangulated and don’t represent reality. Photo courtesy of Brandon Steckler
Now, look at the same signal captured at 500 seconds per division. This leaves us with an hour and 23-minute capture. The sample rate is the same, but those samples are now stretched out across a much longer time frame. As a result, the square wave now appears triangulated and distorted (Figure 6), as if there’s a problem with the sensor or reluctor wheel. But there’s nothing wrong with the system at all — this distortion is simply a limitation of the scope.
I don’t know of a scope, at least in the automotive field, that can record an hour and a half of data and still maintain a high enough sample rate to accurately represent the waveform that would be exhibited from a rotating reluctor wheel past a Hall
effect crankshaft position sensor. The transition time between sample points becomes very deficient.
FINAL THOUGHTS
So, what do you think? As you’ve seen, every single tool I showed you does indeed have a limitation. If you don’t take the time to discover those limitations, you’re doing yourself a disservice. It’ll take you much longer to become the efficient, accurate, and confident diagnostician we all strive to be.
Take the time to pull out your tools, test known good vehicles, and push those tools to their limits. Learn what they can show you and what they can’t. Once you understand that, apply those same tests to faulted vehicles
— you’ll see how well the tools serve you once you know their boundaries. A great benefit of doing this is that you’ll start learning to leverage your tools to infer information — allowing you to make accurate diagnostic decisions without tearing everything apart. Relying on your tools to deliver accurate test results saves time while maintaining accuracy, and that’s the goal. These new, more efficient tests will eventually replace the older, time-consuming ones, so make sure you’re staying ahead of the game.
