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

DESCRIPTION

The outer mirror switch assembly sends a mirror auto 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 in the AUTO position. The main body ECU (multiplex network body ECU) retracts or returns the outer rear view mirror assemblies based on the lock/unlock signal of each door while the ignition switch is off.
