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 test is being performed after performing a repair that did not involve a DTC test, go to next step. If test is being performed after performing a repair that involved a DTC test, go to step 3.
Check if initial symptom still exists. If initial or another symptom exists, repair is not complete. Check for technical service bulletins that apply to symptom. Go to TEST NTC-1: NO TROUBLE CODES TEST MENU and diagnosis by symptom. If initial symptom no longer exists and no DTCs are present, test is complete.
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.
Road test vehicle for at least 5 minutes. If repair involved A/C relay control circuit, ensure A/C is on during road test. Road test vehicle at a speed of at least 40 MPH at some point during road test. Stop vehicle. Turn engine off for at least 10 seconds. Start engine and continue road test. Ensure transmission shifts through all gears. After road test, turn engine off and go to next step.
Using scan tool, read DTCs. If original DTC did not return and there are no new DTCs, test is complete. If original DTC returns or another DTC is present, perform appropriate diagnostic test. See DTC MESSAGES & CODES table under DIAGNOSTIC TROUBLE CODE DEFINITIONS.
