Test VER-5: OBD-II Monitor Verification

NOTE: If Powertrain Control Module (PCM) is replaced, the correct vehicle mileage and Vehicle Identification Number (VIN) must be programmed into the PCM to prevent Diagnostic Trouble Codes (DTC) from being stored in Controller Anti-Lock Brake (CAB) module and Air Bag Control (ACM) module. 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. To program PCM and clear DTCs from CAB and ACM modules, perform PROGRAMMING POWERTRAIN CONTROL MODULE  procedure under POWERTRAIN CONTROL MODULE under PROGRAMMING.
  1. Inspect vehicle to ensure all components related to the repair are properly connected. Reassemble and reconnect components as necessary. If any DTCs have not been diagnosed, perform appropriate DTC test and finish diagnosing remaining DTCs as necessary. If all DTCs have been diagnosed and repaired, ensure fuel tank is at least 1/4 full and all accessories are off. If repair procedure did not include replacing PCM, go to next step. If repair procedure did include replacing PCM, use scan tool to ensure correct VIN and mileage has been programmed into PCM. Go to next step.
  2. If a DTC for OBD-II monitor was repaired, go to next step. If a DTC for a comprehensive component was repaired, turn ignition off for at least 10 seconds. Start engine and operate engine for at least 2 minutes while noting GOOD TRIP counter. If GOOD TRIP counter changes to one or more and no new DTCs exist, repair was complete. If GOOD TRIP counter changes to zero or repaired DTC or new DTC is stored, repair is not complete. Check for related technical service bulletins or flash updates and then proceed to appropriate DTC test.
  3. Proper way to ensure DTC is properly repaired is to allow PCM to run appropriate 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 all enabling conditions and allow applicable OBD-II monitor to run.
  4. While OBD-II monitor is running, scan tool will beep. After OBD-II monitor is complete, view the results. If OBD-II monitor ran and GOOD TRIP counter changed to one or more, repair is complete. If OBD-II monitor failed, repaired DTC or any other DTC is stored, repair is not complete. Check for related technical service bulletins or flash updates and then proceed to appropriate DTC test. If catalyst was replaced, use scan tool, select MISCELLANEOUS, then CATALYST REPLACED and then press ENTER.
