Toyota Sienna Service Manual: Mirror Switch Circuit
DESCRIPTION
- A switch signal of the outer mirror switch is transmitted to the selected outer mirror control ECU by way of the body ECU. Then, the outer mirror control ECU activates the mirror motor to move the mirror UP, DOWN, RIGHT and LEFT in response to the inputs.
HINT: The power mirror control system is part of the multiplex communication system (BEAN). This system features shared communication wiring that reduces the wiring complexity of the communication lines.
The first step in any repair is to confirm the proper operation of the communication system. Proceed with troubleshooting after the communication has been verified (See Multiplex Communication System).
