NGC POWERTRAIN VERIFICATION TEST VER - 2

NOTE: 1. If this vehicle is equipped with a Electronic Throttle Control system, and the APP Sensors, PCM,
or Throttle Body Assembly have been replaced, use a scan tool to perform the ETC RELEARN function.

NOTE: 2. If the PCM or FCM have been replaced, the Pinion Factor MUST be programmed into the FCM.
While programming the Pinion Factor into the FCM the scan tool will send the Pinion Factor information to
the PCM at the same time. Refer to the scan tool for program procedure.

NOTE: 3. If the PCM has been replaced and the correct VIN and mileage have not been programmed, a DTC
will set in the ABS Module, Airbag Module and the SKIM.

NOTE: 4. If the vehicle is equipped with a Sentry Key Immobilizer System, Secret Key data must be updated.
Refer to the Service Information for the PCM, SKIM and the Transponder (ignition key) for programming
information.
5. Inspect the vehicle to make sure that all components related to the repair are properly installed and connected.

6. With a scan tool, clear DTCs and Reset Memory all engine values.

7. Run the engine for one warm-up cycle to verify proper operation.

8. Road test the vehicle. Use all accessories that may be related to this repair.

9. With the scan tool, confirm that no DTC’s are present and that all components are functioning properly.

10. If this test is being performed after a No Trouble Code test, verify the symptom is no longer present.

NOTE: The PCM can detect and compensate for variances in the engine and its components. To learn these
variations, the PCM uses the input of the actual crankshaft rotation pattern and ideal crankshaft rotation
pattern that has been calibrated into the PCM. The PCM then compares the two patterns. The variation
between the two values is the Adaptive Numerator. If the Adaptive Numerator is not learned by the PCM, the
misfire monitor will not run and the Multi-Cylinder Displacement System (MDS) will not operate. Without
MDS operation, the customer will experience decreased fuel economy. If the customer experiences decrease
fuel economy or after any repair use the scan tool to ensure that the Adaptive Numerator is learned.

Are any DTCs or symptoms remaining?

Yes

>> Check for any related Technical Service Bulletins and/or refer to the appropriate Diagnostic Procedure.

No

>> Repair is complete.

1. If this vehicle is equipped with an Electronic Throttle Control system, and the APP Sensors, PCM, or Throttle
Body Assembly has been replaced use a scan tool to perform the ETC RELEARN function.

NOTE: 2. After completing the Powertrain Verification Test the Transmission Verification Test must be per-
formed.

NOTE: 3. If the PCM has been replaced and the correct VIN and mileage have not been programmed, a DTC
will set in the ABS Module, Airbag Module and the SKIM.

NOTE: 4. If the vehicle is equipped with a Sentry Key Immobilizer System, Secret Key data must be updated.
Refer to the Service Information for the PCM, SKIM and the Transponder (ignition key) for programming
information.
5. Inspect the vehicle to make sure that all components related to the repair are properly installed and connected.

6. With the scan tool, clear DTCs.

7. Perform generator output test. Refer to the appropriate service information as necessary.

8. Start the engine and set engine speed to 2000 RPM for at least thirty seconds.

9. Cycle the ignition key off and on.

10. With the scan tool, read the DTCs.

NOTE: The PCM can detect and compensate for variances in the engine and its components. To learn these

NGC POWERTRAIN VERIFICATION TEST VER - 4

NOTE: If this vehicle is equipped with an Electronic Throttle Control system, and the APP Sensors, PCM, or
Throttle Body Assembly have been replaced, use the scan tool to perform the ETC RELEARN function.

NOTE: 2. After completing the Powertrain Verification Test the Transmission Verification Test must be per-
formed.

NOTE: 3. If the PCM has been replaced and the correct VIN and mileage have not been programmed, a DTC
will set in the ABS Module, Airbag Module and the SKIM.

Refer to the Service Information for the PCM, SKIM and the Transponder (ignition key) for programming
information.
5. Inspect the vehicle to make sure that all engine components are properly installed and connected.

6. Connect the scan tool to the data link connector and erase all codes.

7. Turn the speed control ON (if equipped, cruise light will be on).

8. Depress and release the SET Switch when the vehicle speed is greater than 35 MPH. The speed control should
engage and hold the selected speed.

9. Press and hold the RESUME/ACCEL Switch. The vehicle speed should increase by at least 2 MPH.

10. Press and hold the COAST switch. The vehicle speed should decrease.

11. Using caution, press and release the brake pedal. The speed control should disengage.

12. Bring the vehicle speed back up to 35 MPH.

13. Press the RESUME/ACCEL switch. The speed control should resume the previously set speed.

14. Hold down the SET switch. The vehicle should decelerate.

15. Make sure vehicle speed is greater than 35 mph and release the SET Switch. The vehicle should adjust and set
a new vehicle speed.

16. Press and release the CANCEL switch. The speed control should disengage.

17. Bring the vehicle speed back up above 35 mph and engage speed control.

18. Turn the Speed Control Off. (Cruise light will be off). The speed control should disengage.

NOTE: OVERSHOOT/UNDERSHOOT FOLLOWING SPEED CONTROL SET.
20. If the vehicle operator repeatedly presses and releases the SET button with their foot off of the accelerator
(referred to as

9

lift foot set

9

), the vehicle may accelerate and exceed the desired set speed by up to 5 mph (8 km/h).

21. It may also decelerate to less than the desired set speed, before finally achieving the desired set speed.

22. The Speed Control System has an adaptive strategy that compensates for vehicle-to-vehicle variations in speed
control cable lengths.

23. When the speed control is set with the vehicles operators foot off of the accelerator pedal, the speed control
thinks there is excessive speed control cable slack and adapts accordingly.

24. If the

9

lift foot sets

9

are continually used, a speed control overshoot/undershoot condition will develop.

25. To

9

unlearn

9

the overshoot/undershoot condition, the vehicle operator has to press and release the set button

while maintaining the desired set speed using the accelerator pedal (not decelerating or accelerating).

26. Then turn the cruise control switch to the OFF position (or press the CANCEL button if equipped) after waiting
10 seconds.

27. This procedure must be performed approximately 10-15 times to completely unlearn the overshoot/undershoot
condition.
