Toyota Sienna Service Manual: Mirror Motor Circuit

DESCRIPTION

A mirror control switch signal and memorized mirror positions are sent to the outer mirror control ECU.

The outer mirror control ECU drives the selected mirror UP, DOWN, LEFT and RIGHT in response to the inputs.

HINT: The power mirror control system is part of the large-scale multiplex communication system. 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).
