POWER MIRROR CONTROL SYSTEM Front Passenger Side Power Mirror cannot be Adjusted with Power Mirror Switch

DTC Code DTC Name
Front Passenger Side Power Mirror cannot be Adjusted with Power Mirror Switch

SYSTEM DESCRIPTION

When the mirror adjust switch is operated, the main body ECU (multiplex network body ECU) detects the switch operation and sends the mirror adjust switch signal to the outer mirror control ECU assembly RH via CAN communication. Upon receiving the signal, the outer mirror control ECU assembly RH operates the vertical and horizontal mirror motors, which are built into the outer rear view mirror assembly RH, to adjust the mirror surface position.
