  2. In the System Test tab of wiTECH, record the “Last VTA Trigger” cause.
  3. Was the “Last VTA Trigger” equal to 1 (right rear door)?

Yes >>> Perform the repair procedure.No >>> Proceed to Step 4.

  1. Are DTCs U0010 AND U0001 present in the TIPM?

Yes >>> Perform the repair procedure.No >>> This bulletin does not apply. Further diagnosis is required.


Flash reprogram the TIPM. Help using the wiTECH diagnostic application for flashing the TIPM is available through the wiTECH diagnostic application. For instructions, select the HELP tab on the upper portion of the wiTECH window, then “Help Contents.” This will open the Welcome to wiTECH help screen where topics may be selected.Clear any DTCs that may have been set in other modules due to reprogramming.
