Powertrain Verification Test - Ver 5
DIAGNOSTIC TEST1.NGC POWERTRAIN VERIFICATION TEST VER - 5
NOTE: 1. After completing the Powertrain Verification Test the Transmission Verification Test must be performed.
NOTE: 2. 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: 3. 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: 4. 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: 5. When replacing an O2 Sensor, the PCM RAM memory must be cleared, either by disconnecting the PCM C-1 connector or momentarily disconnecting the Battery negative terminal.
6. The NGC learns the characteristics of each O2 heater element and these old values should be cleared when installing a new O2 sensor. The customer may experience driveability issues if this is not performed.
7. Inspect the vehicle to ensure that all engine components are properly installed and connected. Reassemble and reconnect components as necessary.
8. Connect the scan tool to the data link connector.
9. Make sure the fuel tank has at least a quarter tank of fuel. Turn off all accessories.
10. If the Catalyst was replaced, with the scan tool go to the Miscellaneous Menu Option "Catalyst Replaced" and press enter.
11. If a Comprehensive Component DTC was repaired, perform steps 12 - 14. If a Major OBDII Monitor DTC was repaired skip those steps and continue verification.
12. After the ignition has been off for at least 10 seconds, restart the vehicle and run 2 minutes.
13. With the scan tool, monitor the appropriate pre-test enabling conditions until all conditions have been met. Once the conditions have been met, switch screen to the appropriate OBDII monitor, (Audible beeps when the monitor is running).
14. If the repaired OBDII trouble code has reset or was seen in the monitor while on the road test, the repair is not complete. Check for any related technical service bulletins or flash updates and return to Engine Electrical Diagnostic List.
15. If the conditions cannot be duplicated, erase all DTCs with the DRBIII(R).
16. If another DTC has set, return to the Engine Electrical Diagnostic List and follow the path specified for that DTC.
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: Did the OBDII Monitor run successfully and has the Good Trip Counter changed to one or more?
YES: Repair is complete.
NO: Check for any related Technical Service Bulletins.
