GUESTEDITORIAL Buying Counterfeit Scan Tools Goes Way Beyond Just ‘Buyer Beware’ Counterfeit scan tools scare me. I know someone who bought a counterfeit Rolex from a street vendor in New York for $13 several years ago and thought it was fun to fool their friends for a few months while the watch actually worked. However, as a responsible adult accepting the American rule-of-law, that person must accept that they were participating in a scam that was unfair to this Swiss company who has an international right to protect its good name and trademark. For some, it seems harmless to buy a counterfeit watch or purse because it comes with a low expectation of quality and it’s easy to just toss it in the trash when it doesn’t hold up. But I don’t know of any professional technician who is trying to fool their friends with a counterfeit scan tool.
Serious Business Consequences Our business is serious, and we have a high expectation of quality along with a parallel expectation of support for the tool we will depend on. When the counterfeit tool fails, we lose productivity. When the counterfeit tool turns the ECM to a brick, we lose money. When enough independent technicians buy counterfeits, the OEM begins to lose confidence that the aftermarket will indeed be able to service their car owners.
Let me be clear that counterfeit tools are not to be confused with legitimate aftermarket tools, clearly identified as an alternative brand with a real company ready to stand behind their legal production of a competitive product. Counterfeits are items identified by a trademarked name or label that does not belong to the crook who produced it.
Counterfeits and Clones Another scam with scan tools is the “clone” tools that illegally contain copyrighted software or components for which the crook failed to obtain proper license. Both of these types of counterfeit tools scare me, as it puts our whole industry at risk. NASTF OEM and independent volunteers are preparing a presentation on counterfeit tools to be given during the Fall 2013 NASTF General Meeting, Nov. 6, during the AAPEX/SEMA trade shows in Las Vegas. The NASTF event will be free to attend and without pre-registration. However, NASTF recommends early registration for trade show credentials and travel arrangements.

very once in a while a vehicle comes to the shop with a driveability concern and no codes available to aid in the diagnosis. As techs, we use our knowledge and all the tools we have available to try to diagnose the vehicle correctly the first time. Unfortunately, sometimes, we aren’t able to find out exactly what the root cause of the concern is, and the vehicle may leave the shop not repaired and then come back another day as the concern persists or worsens — or not return at all if the customer loses faith with our abilities. This article will try to help you repair driveability concerns the first time and avoid those comebacks. This month, we’ll focus on a loss-of-power concern on vehicles with an electric return-type fuel system. During high-calculated loads and on steep grades, vehicles with an electric return-type fuel system may act as if they’re running out of fuel, and depending on geographical locations, this may happen occasionally or worsen quickly. During all other driving conditions, these vehicles run and perform fine.
Pump Up the Volume While the fuel system may be able to maintain the correct fuel pressure during most driving conditions, the volume, however, can be low and even close to zero and still run. Volume can be influenced by many different factors, so a full analysis must be
completed. Short- and long-term fuel trims (STFT and LTFT) are the adjustments made by the PCM/ECM to maintain the ideal 14.7:1 air/fuel ratio. Total fuel trims are the combination of STFT and LTFT added together. Total fuel trims may be seen on the plus side where PCM/ECM is attempting to richen the fuel mixture by adding fuel to counterbalance an apparent lean condition; however, the condition may not be extreme enough to set a DTC. Checking for low volume can be seen while driving the vehicle and watching the fuel trims or pressure when accelerating. STFT will in-

FUELSYSTEMTESTING crease to the plus side and fuel pressure may drop below the manufacturer’s specifications. Another indication of being lean is if the front oxygen sensor(s)’ voltage(s) do not increase to maximum voltage quickly on acceleration. But this still may not be conclusive evidence of the exact concern. Depending on the severity and vehicle, you may be lucky enough to have lean codes P0171 and P0174 set in memory to help with diagnosing.
Fuel System Breakdown Fuel systems can be broken down into two types: fuel return and returnless. While we’re focusing mostly on return-type systems in this article, returnless-type systems are becoming more popular today due to evaporative emissions and gasoline direct-injected systems. Return-Type Fuel Systems Fuel flow is measured on a return-type fuel system with the continuous flow of fuel from the tank to the fuel rail and excess fuel (not used) flowing back to the fuel tank via the fuel rail pressure regulator. Volume is very important on return systems with electric fuel pumps to make sure we get the correct amount of fuel delivered to the fuel injectors. Before we go any further, now is a good time to check for a good supply of clean voltage. Battery/ charging voltage has tremendous influence on the amount of fuel that flows though the fuel system itself. If the correct voltage is not maintained, the fuel pump may not be able to deliver the correct amount of volume. Remember, the voltage is the pressure or push, so the higher the voltage, the more of a push and the higher the current flow. Be sure to check your charging system before continuing to check the fuel system itself when considering volume. During testing we’ve found that even a one-volt difference can change volume by over one-third. For example, fuel volume at 14.2 volts is 0.5 gallons per minute (gpm) (1.9 liters per minute [lpm]) if the voltage were to be lowered to 13.2 volts, the volume will be lowered to around 0.3 gpm. Keep in mind, the days of a vehicle not cranking from a dead/weak battery are over — batteries do not fail as they did in the past. With computerization and engine control systems today, the engine can start quickly with a minimum amount of voltage. Many concerns associated with battery and voltage can go unnoticed if the vehicle starts and/or cranks quickly. Many customers still assume if the vehicle cranks, then the battery must still be good. Our next step is to check the fuel quality for contami-

nation, most commonly alcohol. An alcohol fuel test kit can be purchased or you can make your own with a graduated cylinder or bottle. Combine one part water to five parts gasoline and shake for 30 seconds, let it sit for approximately 10 minutes for the alcohol to combine with the water. Next, subtract the initial amount of water added from the level of clear liquid and multiply the increased amount by 10 for the alcohol percentage. Alcohol can drive fuel trims to the positive side due to the high oxygen content and the lack of British Thermal Units (BTUs). Flex fuel vehicles have the ability to adjust for increased alcohol; however, if the vehicle is not a flex fuel vehicle, fuel trims can be high, with the system continually trying to richen the mixture. Checking for alcohol is fairly easy, as seen in Figure 1, and should be done with all driveability concerns, lean codes and catalyst codes. During my career of teachFigure 1 ing, I’ve found that most technicians or shops use tools to check electric return-type fuel systems that may result in incorrect data. Most shops have a fuel gauge that connects to the rail with a teed line and a button or valve to drain fuel into a container, see Figure 2. When running the engine, the valve is opened and fuel is delivered into the measFigure 2 ured container. Unfortunately, this fuel measurement tool design doesn’t work very well with electric fuel systems to check volume. When the fuel system is opened to the atmosphere, the pressure drops. This allows the fuel pump to spin faster, delivering more fuel than the actual volume into the measure container, appearing to have plenty of fuel, and giving inaccurate results. Unfortunately, this can lead to test results appearing as if the volume is correct and possibly missing a correct diagnosis. From this point, the technician may move on to diagnose other systems or worse, replace parts trying to

rectify the concern. (This is the vehicle you give back to the customer on a late Friday afternoon knowing right well it isn’t fixed, telling them to try it and see if it is any better — at least you’ll have a peaceful weekend!) When checking the volume correctly in an electric return-type fuel system, it is recommend to use a closed loop fuel system flow tester, see Figure 3. These are typically incorporated with a fuel pressure gauge to check pressure and volume at the same time. These testers have a flow gauge with a float in a clear tube, the float moves to a measured level inside the tube when fuel is flowing. Fuel volume should be consistent and will not
change with throttle opening, engine load or temperature. This allows an accurate test in the shop, eliminating the need of a road test. The average fuel volume is around 0.5 gpm, but you may need to check an aftermarket source if the OE doesn’t supply volume specification. A rule of thumb is about 0.5 gpm or higher. While testing a Ford Taurus, I found the fuel pressure of 35 psi (Figure 4) was within specifications of 30-45 psi Key On Engine Off (KOEO). When checking the flow, it was 0.24 gpm — far below the minimum needed of 0.5 gpm (Figure 5). Quick calculation: a fuel pump that delivers 0.5 gpm will pump 30 gallons per hour (gph). A vehicle

getting 30 miles to the gallon will use 2 gallons of fuel per hour when driving at 60 mph. In the case of the Taurus, 28 gallons of fuel are being returned to the fuel tank per hour. There would have to be a 28-gallon-perhour decrease in fuel volume before a change in pressure would be seen. Another benefit of this fuel system tester is the clear tube that gives a view of the fuel to check for contamination and/or air bubbles in the fuel, see Figure 6. Volume should be a fairly consistent; somewhere between 0.5 to 0.7 gpm. Always refer to manufacturer’s specifications for correct fuel pressure and volume. Check the

FUELSYSTEMTESTING fuel pump relief valve pressure by deadheading the pump; some fuel system tools have a valve that can be turned to block the fuel line for maximum pressure, see Figure 7. In-tank fuel pumps typically have a relief valve to protect the system in case of a fuel line blockage, this valve relieves fuel pressure around 90 psi. This will see if the pump is capable of building pressure high enough to open the relief valve and if the valve is working. Also, it’s a good idea to check the “check valve” — the check valve holds fuel in the fuel lines and rail(s) to maintain pressure when the engine is turned off. If the check valve is bad, the vehicle may exhibit hard starting or vapor lock (fuel boiling in the rail on hot soaks) — remember an increase in pressure increases the boiling point. This is most likely to occur in the spring when switching from winter to summer fuels; winter fuel’s boiling point is about 50° less than summer fuel.
able fuel pump systems, which change fuel pressure as needed during different driving conditions. Some may be mechanical or electronically regulated and will be tested differently. To help complicate things, some vehicles combine a return-type and returnless system into one (running loses fuel supply) changing back and forth as load and rpms change. Using tools and equipment to provide correct information and data for accurate diagnosing is important to repair the vehicle correctly the first time. Always remember your repair is only as good as your knowledge, tools and parts when diagnosing and repairing a vehicle. An educated technician does in the beginning what an uneducated technician does in the end. TS
Returnless-Type System Checks Fuel system testers are useful on returnless-type systems as well to check for relief and check valves along with contamination and aeration. Returnless systems have very little if no measureable flow when measured with a closedloop flow gauge. Fuel pressure also may not be very helpful when checking using a mechanical fuel pressure gauge; most specifications refer to the Fuel Rail Pressure (FRP) sensor reading from scan tool data, which is referenced from manifold vacuum. Mechanical gauge pressure is referenced from atmospheric pressure and will not match the FRP sensor reading. Also, don’t overlook engine vacuum and back pressure. Remember to research the specific vehicle you’re working on. Some vehicles use vari-

imple techniques will often allow us to diagnose problems without a significant investment of time and effort. Knowledge, experience and observation are at the core of successful unconventional diagnostics. The ability to see and understand things that others may miss will make the difference between your shop and your competition. Unconventional methods do not necessarily involve the use of expensive equipment and devices. It can be just a simple observation and some “tricks of the trade.” For example, you can hold your hand close to the exhaust pipe, which could help determine if the engine is misfiring. However, unless you have the ability and knowledge to combine methods — unconventional as well as conventional — depending on the task at hand, you may not be successful in your diagnosis.

both pins, there is a short to ground somewhere. The short to ground could be either in the wiring itself, or in the control unit. We cannot directly test the transistor itself. However, since the protection diode is often built into the transistor, then, in case of damage, both are usually damaged. The diode is connected across the transistor in reverse polarity. In order to check the diode, we connect the DMM test probes in reverse polarity as well. With properly connected test probes, the current will go through the diode, and the display will show the forward voltage drop of the diode. See Figure 1, in which the DMM shows that the wiring to the control unit has continuity. How does this work? Figure 2 shows a DMM in the diode test mode. In this mode, the meter delivers approximately 1.5V to the meter leads. The voltage is delivered through a fairly large value resistor and the meter circuit reads the voltage at the probe leads. (See Figure 3.) If the leads are shorted together, or they are connected across a small resistance, the meter will read 0V or close to it. The reading is the voltage at the meter leads after the resistor. In this mode, any voltage larger than 999 mV will cause the meter to read “1”.

variable resistor. If we reduce the resistance of the resistance box, the voltage output from the DMM in the diode test mode will be less and the display will show a voltage value lower than 1,000 mV. A DMM in the diode test mode (and to some
degree also in the resistance test mode) can be used as a low voltage source that can provide 0-1,000 mV, to simulate some sensors. In another example, the scan tool showed that a diagnostic trouble code (DTC) for the knock sensor had set. There are several possible causes for the DTC, such as a bad sensor, bad wiring, bad control unit or the sensor itself is not properly torqued. The sensor can be checked with a DMM and here is how: The sensor itself has a very high internal resistance and normally the DMM cannot measure it. However, some manufacturers integrate a resistor into the knock sensor to be able to test the circuitâ€™s integrity (shorts, opens, low and high resistance). The value is commonly 50-100 k ohms. How can a knock sensor without the built-in resistor be checked? The piezo element in the knock sensor is, in addition to a voltage-generating device, also a capacitor. We can measure the capacitance, using the DMM. Most knock sensors have a capacitance of approximately 9001,300 pF. The wiring from the control unit to the sensor may add a significant amount of capacitance. This capacitance may need to be accounted for. The knock sensor can be checked to some degree simply by measuring the output voltage from the sensor when tapped. This method does have some significant drawCircle #18 for Reader Service

backs: The signal from the knock sensor is of very short duration. Because the DMM needs some time to sample the signal and cannot continously sample it, we will get different measured voltages for each tap, even if we tap the sensor with the same effort. If the DMM is equipped with a function that
records and displays maximum voltage, that function can be helpful in this case. The knock sensor is often mounted on the cylinder block in an inaccessible location. Tapping on the sensor may not be possible for that reason. High-end DMMs such as the meter shown in Figure 5 tend to
have a number of functions in addition to the basic ACV, DCV, Ohms, diode test, DCA and ACA modes. Some additional functions to look for are temperature, frequency, transistor and capacitance tests. Some DMMs will also remember the minimum and maximum values of any given measurement as

Medium-range meters may only have a max hold mode and no min hold mode, however. The max hold mode can be useful to us in many cases. For example, you can use the max hold mode to check the voltage on the stop lamp bulbs without needing an assistant. Enabling this mode on the multimeter, we can move to press the brake pedal. A multimeter will measure and memorize the maximum voltage present at the bulbs while you depress the brake pedal. See Figure 6. Sometimes we want to be able to measure the minimum voltage in a

negative part of the circuit and the black test lead to the positive part of the circuit. The multimeter will show a negative voltage, but we know that this is not the case. If we are suspecting a bad connection somewhere, we can twist and bend wiring and connectors without having to constantly watch the meter for voltage dips. If the meter shows anything less than the nominal voltage in the circuit, we know there is a bad connection somewhere in what we just tested. We can also use this technique to measure and record voltage drops when starting the engine. This can be very useful when diagnosing complaints of poor starting or charging. The actual starting of the engine may take less than one second, so it may be desirable to disable the sluggish auto range function in the DMM. Just set the range to something on the order of 1 to 2 volts or so, since the voltage drop should be very small. If the meter shows OL when performing this test, increase the range and try again. One problem with this technique is that the max hold function will show 0 volts if we disconnect the multimeter probes, accidentally or otherwise. This is because 0V is larger than a negative voltage. The next installment of Unconventional Diagnostic Methods will tackle more diagnostic tips and tricks for your DMM. TS

NEWS 90-Year-Old Italian Tool Company Testing the Waters in the U.S. Market A brand name as well-known in Europe as Ferrari, family-owned Italian tool company Beta Utensili S.p.A. is looking to test the water on this side of the pond, with a new distribution agreement with Peerless Hardware in Pennsylvania.

TECH TIP Heater Core Leak Repair A classic sign of a heater core problem is when the inside of the vehicleâ€™s windshield persistently keeps misting. Warm coolant is leaking out of the core into the vents and then condensing against the cooler surface of the windshield. The automatic response is to turn up the blowers to try and clear the mist, but this only compounds the problem. The solution is usually to remove and either repair or replace the heater core. However, this is a particularly time-consuming task, which on older vehicles is often not cost-effective. An alternative solution is to treat the cooling system with a total coolant leak repair additive. These are designed to flow throughout the cooling system, including through the heater core, to make a quick and low-cost repair. Look for a ceramicbased, coolant-friendly product; ideally one that conforms to ASTM D-3147. This solution is brought to you by K-Seal www.kseal.com.
