Inspection Procedure

NOTE:
  • The power mirror control system is a part of the multiplex communication system. This system features shared communication wiring that reduces the wiring complexity of the communication lines. The first step in any repair is to confirm the proper operation of the communication system. Proceed with troubleshooting after the communication has been verified (See Multiplex Communication System. Refer to HOW TO PROCEED WITH TROUBLESHOOTING ).
  • The mirror heater operation is liked with the defogger system or wiper and washer system. Confirm that these systems are operating normally before starting the inspection.
