Diagnostic Test

1.NGC POWERTRAIN VERIFICATION TEST VER - 3

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 performed.

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 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.

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 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 Technical Service Bulletins and/or refer to the appropriate Diagnostic Procedure.

No

- Repair is complete.
