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

SYSTEM DESCRIPTION

When the retractable outer mirror switch is pushed, the main body ECU (multiplex network body ECU) received retract/return signal from the retractable outer mirror switch. 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.
