Driving Position Memory Switch Circuit (w/ Memory)
DESCRIPTION
When the seat memory switch M1 or M2 is pressed, the position control ECU & switch (Seat ECU) transmits a signal of the memorized mirror position to the outer mirror control ECU by way of the power window regulator master switch. Then, the outer mirror control ECU drives the mirror motor.
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).
