POWER MIRROR CONTROL SYSTEM (w/ Memory) > Mirror Motor Circuit

for Preparation Click here


DESCRIPTION

Mirror control switch and memorized mirror position signals (from the position control ECU & switch (seat ECU)) are sent to the mirror control ECU. The mirror control ECU moves the selected mirror UP, DOWN, LEFT and RIGHT in response to the input.

HINT:
The power mirror control system is a part of the 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 the Multiplex Communication System).
