- Power Mirror cannot be Adjusted with Power Mirror Switch

SYSTEM DESCRIPTION

The main body ECU (multiplex network body ECU) detects the mirror adjust switch status and sends the signal to the outer mirror control ECU assembly via CAN communication. Upon receiving the signal, each outer mirror control ECU assembly operates the vertical and horizontal mirror motors to adjust the mirror surface position.
