POWER MIRROR CONTROL SYSTEM(w/ Retract Mirror) Front Passenger Side Power Mirror cannot be Adjusted with Power Mirror Switch

SYSTEM 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, LH*2 via CAN communication. The outer mirror control ECU assembly RH*1, LH*2 receives the remote mirror selection signal and up/down/left/right signals and operates the outer rear view mirror assembly RH*1, LH*2 up/ down/left/right based on the signals.
