Recommendation/Instructions:
Inspect Instrument Panel and Steering Column Wire Harnesses for damage. There are three areas to inspect. The first location is near SP200 on the Instrument Panel Insulator Panel. Lower the Instrument Panel Insulator Panel. Inspect wire harness (1) attached to the panel. It may have been caught on the mounting stud (2) located on the inboard forward side. Circuits that potentially could be damaged are listed below. Ensure the harness is rerouted as shown (6).
