Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 9 - ENGINE -
DIAGNOSIS AND TESTING).
Diagnostic Test
1.ACTIVE DTC
NOTE: The most likely cause of this DTC is a plugged intake air system or dirty Throttle Body. Check for
any TSB’s before continuing.
NOTE: Diagnose any 5-Volt Supply, TP Sensor, Oxygen Sensor, Fuel related or MAP Sensor DTCs before
continuing.
NOTE: The throttle plate should be free from binding and carbon build up.
NOTE: Question the customer about weather conditions, as ICE build up on the blade can cause this fault
when ambient is around +4 to -10 Celsius range.
Ignition on, engine not running.
With a scan tool, read DTCs.
Is the DTC active at this time?

1.DTC INFORMATION
NOTE: If a pedal assembly becomes mechanically stuck the voltage output will stay fixed, if this is also
Followed by a long application of the brakes this code will set.
NOTE: When this code sets the pedal position in the PCM software will ramp toidle. If the Pedal voltage
changes OR the brake pedal is released, the pedal position in the PCM software will ramp up to the pedal
position and the ETC light will go out.
With a scan tool, read DTCs and record the related Freeze Frame data.
Diagnose all other Stop Lamp Switch and APP Sensor codes before continuing.
This code can be set by a driver who uses both feet while driving, one for the Accelerator Pedal and the other for
the Brake Pedal.
NOTE: The most likely cause of this DTC is caused by the customer Brake Torquing the engine by pressing
the Accelerator pedal and the pressing the Brake Pedal.
Ask the driver of the vehicle if these conditions apply to their driving habits.
Are the listed conditions part of the customers driving habits?

POWERTRAIN VERIFICATION TEST VER - 4 (DIESEL)
1.POWERTRAIN VERIFICATION TEST VER - 4 (DIESEL)
1. Check if any of the following conditions exist.
2. The ECM has been disconnected or replace.
3. The Battery power has been disconnected.
4. Inspect the vehicle to ensure that all engine components are properly installed and connected. Reassemble and
reconnect components as necessary.
5. With the DRBIII
,eraseDTCs.
6. If the ECM has been replaced, perform steps 11 through 13, then continue with the verification.
7. If ECM has been changed and correct VIN and mileage have not been programmed, a DTC will be set in ABS
and Air bag modules. In addition, if vehicle is equipped with a Sentry Key Immobilizer Module (SKIM), Secret Key
data must be updated to enable start.
8. For ABS and Air Bag systems: Enter correct VIN and Mileage in ECM. Erase codes in ABS and Air Bag modules.
9. For SKIM theft alarm: Connect DRBIII
to data link conn. Go to Theft Alarm, SKIM, Misc. and place SKIM in
secured access mode, by using the appropriate PIN code for this vehicle. Select Update the Secret Key data. Data
will be transferred from SKIM to PCM
10. Turn the speed control ON (if equipped, cruise light will be on).
11. Depress and release the SET Switch. If the speed control did not engage,the repair is not complete. Check for
TSBs that pertain to speed control problem and then, if necessary, return to Symptom List.
12. Depress and hold the RESUME/ACCEL Switch. If the vehicle speed did not increase by at least 2 mph, the
repair is not complete. Check for TSBs that pertain to speed control problem and then, if necessary, return to Symp-
tom List.
13. Press and hold the COAST switch. The vehicle speed should decrease. If it did not decrease, the repair is not
complete. Check for TSBs that pertain to speed control problem and then, ifnecessary, return to Symptom List.
14. Using caution, depress and release the brake pedal. If the speed control did not disengage, the repair is not
complete. Check for TSBs that pertain to speed control problem and then, ifnecessary, return to Symptom List.
15. Bring the vehicle speed back up to 35 MPH.
16. Depress the RESUME/ACCEL switch. If the speed control did not resume the previously set speed, the repair
is not complete. Check for TSBs that pertain to speed control problem and then, if necessary, return to Symptom
List.
17. Hold down the SET switch. If the vehicle did not decelerate, the repair is not complete. Check for TSBs that
pertain to speed control problem and then, if necessary, return to SymptomList.
18. Ensure vehicle speed is greater than 35 mph and release the SET Switch. If vehicle did not adjust and set a
new vehicle speed, the repair is not complete. Check for TSBs that pertain to speed control problem and then, if
necessary, return to Symptom List.
19. Depress and release the CANCEL switch. If the speed control did not disengage, the repair is not complete.
Check for TSBs that pertain to speed control problem and then, if necessary, return to Symptom List.
20. Bring the vehicle speed back up above 35 mph and engage speed control.
21. Depress the OFF switch to turn OFF, (Cruise light will be off). If the speed control did not disengage, the repair
is not complete. Check for TSBs that pertain to speed control problem and then, if necessary, return to Symptom
List.
22. If the vehicle successfully passed all of the previous tests, the speedcontrol system is now functioning as
designed. The repair is now complete.
23. NOTE: OVERSHOOT/UNDERSHOOT FOLLOWING SPEED CONTROL SET.
24. If the vehicle operator repeatedly presses and releases the SET buttonwith their foot off of the accelerator
(referred to as
lift foot set), the vehicle may accelerate and exceed the desired set speed by up to 5 mph (8km/h).
25. It may also decelerate to less than the desired set speed, before finally achieving the desired set speed.
26. The Speed Control System has an adaptive strategy that compensates forvehicle-to-vehicle variations in speed
control cable lengths.
27. When the speed control is set with the vehicles operators foot off of theaccelerator pedal, the speed control
thinks there is excessive speed control cable slack and adapts accordingly.
28. If the
lift foot setsare continually used, a speed control overshoot/undershoot condition will develop.
29. To
unlearnthe overshoot/undershoot condition, the vehicle operator has to press and release the set button
