DESCRIPTION
If any of the M1 or M2 seat memory switch is pressed, the outer mirror control
ECU assembly LH detects the switch operation and sends the seat memory switch signal
to the main body ECU (multiplex network body ECU) via CAN communication. The main
body ECU (multiplex network body ECU) sends the reproduction signal to each outer
mirror control ECU assembly via CAN communication. When receiving the reproduction
signal, each outer mirror control ECU assembly operates the vertical and horizontal
mirror motors, which are built into the outer rear view mirror assembly, to adjust
the mirror surface to the stored position.

CAUTION / NOTICE / HINT
NOTICE:
The power mirror control system uses the CAN communication system. First, confirm
that there is no malfunction in the CAN communication system. Refer to the How to
Proceed with Troubleshooting procedure.
