DESCRIPTION
The outer mirror switch assembly (mirror retract switch) sends the auto retractable outer mirror switch signal to the main body ECU (multiplex network body ECU). The main body ECU (multiplex network body ECU) sends the auto retract/return signal to the outer rear view mirror assemblies, which then control the mirrors.
When the main body ECU (multiplex network body ECU) receives a door lock output signal while the outer mirror switch assembly (mirror retract switch) is in the auto position, the main body ECU (multiplex network body ECU) operates the power retract mirror motors built into the outer rear view mirror assemblies to retract or return the outer rear view mirror assemblies.

CAUTION / NOTICE / HINT
Note
If necessary, the function can be set to the default setting through the customize function.
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.
