Test VER-5
NOTE:
If replacing Powertrain Control Module (PCM), the correct vehicle mileage and Vehicle Identification Number (VIN) must be programmed into PCM to prevent Diagnostic Trouble Codes (DTC) from being stored in Anti-Lock Brake System (ABS) 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.
- Inspect vehicle to ensure all engine components are connected. Reassemble and reconnect components as necessary. If any DTCs have not been diagnosed, perform appropriate diagnostic test. See DTC MESSAGES & CODES table under DIAGNOSTIC TROUBLE CODE DEFINITIONS. If all DTCs have been diagnosed and repaired, go to next step.
- Connect scan tool to Data Link Connector (DLC), if not previously done. Ensure fuel tank is at least 1/4 full. Ensure A/C is off. Go to next step.
- If repair procedure did not include replacing PCM, go to next step. If PCM has been replaced and has already been programmed, go to next step. If PCM has been replaced but has not been programmed, program PCM and clear DTCs. See PROGRAMMING . After PCM is programmed, go to next step.
- Ensure all DTCs are cleared from PCM. Proper way to ensure DTC is properly repaired is to allow PCM to run the OBD-II monitor. OBD-II monitor operation may be observed on the scan tool. In order for OBD-II monitor to be run, certain pretest enabling conditions must be met. Refer to applicable OBD-II monitor pretest screen on scan tool for monitor enabling conditions.
- Operate vehicle within enabling conditions and allow applicable OBD-II monitor to run. While OBD-II monitor is running, scan tool will beep and IN PROGRESS will be displayed on the OBD-II monitor screen. After OBD-II monitor is complete, view the results. OBD-II monitor may have to fail more than once in order for DTC to be stored in PCM. If OBD-II monitor fails, repaired DTC has reset, or any DTCs exist, repair is not complete. Check for related technical service bulletins and proceed to appropriate DTC test. See DTC MESSAGES & CODES table under DIAGNOSTIC TROUBLE CODE DEFINITIONS. If GOOD TRIP counter changes to one or more and no new DTCs exist, repair was successful and test is now complete.
