POWER MIRROR CONTROL SYSTEM (w/ Memory) Driver 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 (driver door) via CAN communication. On receiving the signal, the outer mirror control ECU assembly (driver door) operates the vertical and horizontal mirror motors, which are built into the outer rear view mirror assembly (driver door), to adjust the mirror surface position.
