DESCRIPTION

The retractable outer mirror switch sends a voltage signal to the main body ECU (multiplex network body ECU) in accordance with switch operation (switch input signal). The main body ECU (multiplex network body ECU) uses CAN communication to send this information to the outer mirror control ECU assembly, which then controls the mirrors.

When the outer mirror control ECU assembly receives a door lock signal from the main body ECU (multiplex network body ECU) while the retractable outer mirror switch is in the AUTO position, the outer mirror control ECU assemblies operate the retract motors built into the outer rear view mirror assemblies to retract or return the outer rear view mirror assemblies.
