Powertrain Verification Test VER-5
NOTE:
If replacing the PCM, the correct vehicle mileage and Vehicle Identification Number (VIN) must be programmed into PCM to prevent DTCs from being stored in Controller Anti-Lock Brake (CAB) module, and Air Bag Control Module (ACM). If replacing PCM and vehicle is equipped with a Smart Key Immobilizer Module (SKIM), secret key data must also be updated to enable engine starting. See PROGRAMMING . After completing this verification test, the 42LE Transmission verification test must be performed.
- Inspect vehicle to ensure all engine components are connected. Reassemble and reconnect components as necessary.
- Connect DRBIII® scan tool to Data Link Connector (DLC), if not previously done. Ensure fuel tank is at least 1/4 full. Turn off all accessories.
- Ensure all DTCs are cleared. If a Comprehensive Component DTC was repaired, go to next step. If a Major OBD-II Monitor DTC was repaired, go to step 5.
- After the ignition has been off for at least 10 seconds, restart the vehicle and run for 2 minutes. Go to step 6.
- Using DRBIII® 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 OBD-II monitor (audible beeps are heard when the monitor is running). Go to next step.
- If the conditions cannot be duplicated, clear all DTCs. Did the OBD-II Monitor test run successfully and has the Good Trip counter changed to one or more? If yes, test is complete. Perform transmission verification test. See 42LE TRANSMISSION VERIFICATION TEST VER-1 . If no, check for any related technical service bulletins that apply to symptom. If repaired DTC has reset, proceed to appropriate DTC test. See DIAGNOSTIC TROUBLE CODE DEFINITIONS . If necessary, go to INTERMITTENTS in appropriate TROUBLE SHOOTING - NO CODES article for diagnosis by symptom.
