POWER MIRROR CONTROL SYSTEM (w/ Retract Mirror) - Power Retractable Mirrors do not Operate with Power Retract Mirror Switch


SYSTEM DESCRIPTION

When the outer mirror switch assembly is pushed, the main body ECU (multiplex network body ECU) received retract/return signal from the outer mirror switch assembly. Then main body ECU (multiplex network body ECU) sends the retract/return signal to outer mirror control ECU LH and RH via the CAN communication line. The outer mirror control ECU assembly then performs control in response to the retract/return signal.
