Diagnostic Test

  1. VERIFY THAT THE DTC IS ACTIVE 
    1. Turn the ignition on.
      NOTE:

      Before continuing, review and check for the following:

      • Review the repair history of the vehicle.
      • Ensure that the vehicle has the correct PCM and WCM/SKREEM installed by verifying the part numbers.
      • With the scan tool, ensure that the PCM and WCM/SKREEM are programmed correctly. Compare the PCM VIN to the WCM/SKREEM VIN and ensure the two VINs match.
