POWER MIRROR CONTROL SYSTEM(w/ Retract Mirror) AUTO Power Retract Mirrors do not operate

DESCRIPTION

When the retractable outer mirror switch is set to auto (neutral position), an auto signal is detected by the main body ECU (multiplex network body ECU). When locking and unlocking all doors with the engine switch off, the main body ECU (multiplex network body ECU) sends return/retract signals to the outer mirror control ECU assembly via CAN communication. The outer mirror control ECU assembly returns and retracts the outer rear view mirror assembly based on the received signals.
