V ehicle Modifications

Alterations the vehicle, such changes the wheel base (either lengthening shortening), the addition auxiliary lift axle removal a factory - installed auxiliary lift axle, major body changes, such conversion a tractor a truck axle, suspension steering system component modification, are NOT allowed, these changes will adversely fect performance the road stability system. Should such changes unavoidable, the system must disabled having a qualified technician replace the Advanced60™ ECU with a Premium60™ ECU.

The following additional changes MUST NOT made - vehicle:

• Changes maximum steering angle (to the left right)

• Changes steer axle and/or drive axle track width

• Changing the front and/or rear brake drums drums having a dif ferent flange thickness

T ire Size Calibration

The ECU requires a precise rolling circumference ratio between the front steer axle and the rear drive axles for optimum performance the For this the system continuously calculates the precise ratio and stores the information the ECU memory

Precautions When Installing Electrical Equipment

Connecting electrically powered electrically controlled equipment the vehicle may cause interference with other vehicle components (e.g., the ABS system). The amount interference will depend the operating frequency any new signals and the degree which transient signals are coupled into the vehicle system.

Note: Whenever new electrical equipment installed, the obligation the installer ensure that the new equipment does not interfere with the proper operation all other electrical systems the vehicle. new electrical equipment installed, a vehicle checkout procedure should performed.

Perform the checkout procedure under the following conditions:

• Engine running https://www.truck-manuals.net/mack/

• Brake system air pressure operating range

• V ehicle stationary

• Brake pedal fully depressed

Operate the new equipment under all starting, running and shutdown conditions.

Listen for signs air exhausting from ABS modulator valves (which indication interference

Correct all interference conditions before operating the vehicle.

Note: The center pin the standard seven - pin trailer electrical connector has been standardized the dedicated connection for uninterrupted power for trailer This pin always hot when the tractor ignition turned on.

Danger

Some trailers manufactured prior the trailer ABS regulations may use the center pin power certain trailer auxiliary equipment. The possibility exists that this auxiliary equipment may unexpectedly activated the truck tractor electrical system, resulting personal injury damage equipment. Caution must used when connecting the trailer electrical connector ensure that power the center pin will not unintentionally activate any trailer auxiliary equipment.

Automatic T raction Control TC) (If Equipped)

Automatic T raction Control TC) provides improved traction slippery surfaces reducing wheel spin. The system operates automatically follows:

• a drive wheel starts A applies air pressure the brake the spinning wheel. Doing this transfers engine torque the wheels that have better traction.

• all drive wheels are A limits engine torque reduces wheel spin provide improved

When A automatically becomes active, the A indicator lamp turns alert the operator . The lamp turns f when the wheel(s) stops spinning.

Heavy Mud/Snow Function (If Equipped)

A may also include a heavy mud/snow function which allows the operator activate A when additional traction This function activated with https://www.truck-manuals.net/mack/ the A mode switch which located the dashboard. The heavy mud/snow function increases available traction increasing permissible wheel spin.

When the operator selects the heavy mud/snow the A indicator lamp blinks continuously The A lamp stops blinking when the A mode switch turned https://www.truck-manuals.net/mack/

The instrument cluster also contains ABS tell - tale lamp, which indicates when there a problem being reported the T railer ABS system.
