July 1: So it begins. Don't worry, this is not in the correct legal jurisdiction!

System Inspection

  1. Was the PCM/ECM just replaced or reflashed?

    YES 

    NO 

    • Using a GDS, read VIN information.

      If there is no proper VIN information, perform "VIN WRITING " procedure.

      If VIN information exists, substitute with a known-good PCM/ECM and check for proper operation. If the problem is corrected, replace PCM/ECM.

      And go to "VERIFICATION OF VEHICLE REPAIR " procedure.
