Powertrain Verification Test VER 1

  1. Inspect the vehicle to ensure that all engine components are properly installed and connected. Reassemble and reconnect components as necessary.
  2. Inspect the engine oil for contamination. If oil contamination is suspected, change the oil and filter.
  3. If the PCM was not replaced, skip steps  4 through  6 and continue the verification.
  4. If the PCM was replaced, the correct VIN and mileage must be programmed or a DTC will set in the ABS and Air Bag modules. In addition, if the vehicle is equipped with Sentry Key Immobilizer Module (SKIM), Secret Key data must be updated to enable start.
  5. For ABS and Air Bag systems, enter correct VIN and Mileage in PCM. Erase codes in ABS and Air Bag modules.
  6. For SKIM theft alarm, connect DRBIII(R) to data link connector. Go to Theft Alarm, SKIM, Misc. and place SKIM in secured access mode by using the appropriate PIN code for this vehicle. Select Update the Secret Key data. Data will be transferred from SKIM to PCM.
  7. Attempt to start the engine. Is the vehicle still unable to start or are there any DTCs or symptoms remaining? If yes, check for any related Technical Service Bulletins and/or see DIAGNOSTIC TROUBLE CODE IDENTIFICATION  or SYMPTOM IDENTIFICATION  tables under RETRIEVING & CLEARING DIAGNOSTIC TROUBLE CODES under SELF-DIAGNOSTIC SYSTEM. If no, repair is complete.
