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

DESCRIPTION

When the outer mirror switch assembly mirror retract switch is operated, return/retract signals are sent to the main body ECU (multiplex network body ECU). The main body ECU (multiplex network body ECU) sends return/retract signals to the outer mirror control ECU assembly via CAN communication. The outer mirror control ECU assembly returns and retracts the outer rear view mirror assembly based on the received signals.
