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

DESCRIPTION

The outer mirror switch assembly sends a mirror retract/return signal to the main body ECU (multiplex network body ECU) when the retractable outer mirror switch on the outer mirror switch assembly is operated. The main body ECU (multiplex network body ECU) retracts or returns the outer rear view mirror assemblies based on the signal.

CAUTION / NOTICE / HINT

Note


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


    • *: w/ Smart Entry and Start System

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

  • 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.*
