POWER MIRROR CONTROL SYSTEM(w/o Memory) Power Retractable Mirrors do not Operate with Power Retract Mirror Switch

DESCRIPTION

When the outer mirror switch assembly (mirror retract switch) is operated, a retract/return signal is received by the main body ECU (multiplex network body ECU). The main body ECU (multiplex network body ECU) retracts and returns the outer rear view mirror assembly based on the received signal.

CAUTION / NOTICE / HINT

Note


  • Inspect the fuses for circuits related to this system before performing the following inspection procedure.

  • If the main body ECU (multiplex network body ECU) is replaced, refer to the Service Bulletin.

  • As the door control battery is installed between the vehicle battery and main body ECU (multiplex network body ECU), first perform the inspections in On-Vehicle Inspection to confirm that there are no malfunctions in the power source circuit for the main body ECU (multiplex network body ECU) before performing this troubleshooting procedure.*
