    Possible Causes 

    • Network communication concern
    • PCM

  2. QA1 CARRY OUT A VEHICLE INSPECTION AND VERIFY THE SELF-TEST PROCEDURE

    • NOTE: Check for BCM DTCs. Diagnose all PCM circuit DTCs retrieved from the BCM before entering this pinpoint test. Refer to the appropriate service information article for the BCM DTC diagnosis.

    • NOTE: If the self-test or communication concern occurred after a failed or an aborted reprogram, the module may be blank. Attempt to reprogram the module again before continuing with this pinpoint test.

    • Visually inspect the following for obvious signs of electrical damage:

      • harness wiring
      • electrical connections
