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.
