POWER MIRROR CONTROL SYSTEM Power Mirror cannot be Adjusted with Power Mirror Switch

DESCRIPTION

This circuit detects the conditions of the outer mirror switch assembly.

The outer mirror switch assembly sends information about the operating condition of the mirror switch (switch input signals) through the multiplex communication line. Then the switch input signals are sent to the outer mirror control ECU assembly. Mirror adjustment is controlled by the outer mirror control ECU assembly.

Tech Tips

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 Multiplex Communication System: Click here.
