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

DESCRIPTION

The main body ECU (multiplex network body ECU) receives the retractable outer mirror switch signal from the outer mirror switch assembly (retractable outer mirror switch). The main body ECU then sends the mirror retract/return signal to each outer mirror control ECU assembly via CAN communication. Based on this signal, each outer mirror control ECU assembly retracts or returns the outer rear view mirror assembly.
