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 Controller Anti-Lock Brake (CAB), Smart Key Immobilizer Module (SKIM), if equipped and Occupant Restraint Controller (ORC). If replacing PCM and vehicle is equipped with a 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. Using scan tool, clear DTCs. Run engine for one warm-up cycle to verify proper operation. Road test vehicle and use all accessories that may be related to repair.
Using scan tool, confirm no DTCs or secondary indicators are present and that all components are functioning properly. Verify symptom is no longer present. If symptom is still present or any other symptom is present, go to TROUBLE SHOOTING - NO CODES - CARAVAN, TOWN & COUNTRY, & VOYAGER article for additional testing. Also, check for any technical service bulletins that may apply.
Using scan tool, read DTCs. If any DTCs are present, perform appropriate test. See DIAGNOSTIC TROUBLE CODE DEFINITIONS in SELF-DIAGNOSTICS - CARAVAN, TOWN & COUNTRY, & VOYAGER article. If no DTCs are present and all components are functioning properly, repair is complete.
