Toyota Venza: Front Passenger Side Power Mirror cannot be Adjusted with Power Mirror Switch

Toyota Venza Service Manual / Mirror (ext) / Power Mirror Control System(w/ Memory) / 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 (driver side junction block assembly) detects the switch operation and sends the mirror adjust switch signal to the outer mirror control ECU assembly (front passenger door) via CAN communication. On receiving the signal, the outer mirror control ECU assembly (front passenger door) operates the vertical and horizontal mirror motors, which are built into the outer rear view mirror assembly (front passenger door), to adjust the mirror surface position.
