Powertrain Verification Test - Ver 1

DIAGNOSTIC TEST

1. NGC POWERTRAIN VERIFICATION TEST VER - 1

NOTE: 1. If this vehicle is equipped with an Electron 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 PCM, SKIM and the Transponder (ignition key) for programming information.

NOTE: 5. Inspect the vehicle to ensure that all components related to the repair are properly installed and connected.

NOTE: 6. Inspect the engine oil for fuel contamination. Replace the oil and filter as necessary.

NOTE: 7. Attempt to start the engine.

NOTE: 8. If the No Start condition is still present, refer to the Engine Electrical Diagnostic list and perform the diagnostic testing as necessary, refer to any Technical Service Bulletins that may apply.

NOTE: 9. Run the engine for one warm-up cycle to verify operation.

NOTE: 10. With the scan tool, confirm that no DTCs or Secondary Indicators are present and that all components are functioning properly.

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.

Q: 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.
