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.
