DESCRIPTION
When the outer mirror switch assembly mirror surface adjust switch (up/down/left/right) is operated, up/down/left/right signals are received by the main body ECU (multiplex network body ECU). The main body ECU (multiplex network body ECU) sends the received signals to the outer mirror control ECU assembly RH*1 and LH*2 via CAN communication. The outer mirror control ECU assembly RH*1 and LH*2 receives the remote mirror selection signal and up/down/left/right signals and operates the outer rear view mirror assembly RH*1 and LH*2 up/down/left/right based on the signals.
