POWER MIRROR CONTROL SYSTEM(w/o Memory) AUTO Power Retract Mirrors do not operate

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 retract position, the main body ECU (multiplex network body ECU) operates the retract motors built into the outer rear view mirror assemblies to retract or return the outer rear view mirror assemblies.
