Fuel System/Misfire Monitor Verification Test

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.
  1. 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 DIAGNOSTIC TROUBLE CODE DEFINITIONS . If all DTCs have been diagnosed and repaired, go to next step.
  2. Connect DRBIII® 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.
  3. If repair procedure did not include replacing PCM, or 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 has been programmed, go to next step.
  4. Ensure misfire detection is enabled if a misfire DTC was repaired. Low fuel level or an unlearned adaptive numerator can disable the misfire monitor. If PCM has been replaced or disconnected during testing, the adaptive numerator must be relearned in order for misfire monitor to run.
  5. Using DRBIII®, monitor Similar Condition and attempt to duplicate conditions during which vehicle was operating at when DTC was set. If conditions cannot be duplicated, clear DTCs. Has the OBD-II monitor test failed or are any DTCs or symptoms remaining? If no, test is complete. If yes, 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 TROUBLE SHOOTING - NO CODES - CARS - EXCEPT SEBRING COUPE & STRATUS COUPE article for diagnosis by symptom.
