Mirror Switch Circuit

MIRROR: POWER MIRROR CONTROL SYSTEM (w/ Memory): Mirror Switch Circuit

Mirror Switch Circuit

DESCRIPTION

A switch signal of the outer mirror switch is transmitted to the selected outer mirror control ECU by way of the body ECU. Then, the memory mirror ECU activates the mirror motor to move the mirror UP, DOWN, RIGHT and LEFT in response to the inputs.

HINT: The power mirror control system is 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). WIRING DIAGRAM

INSPECTION PROCEDURE

PROCEDURE

1. INSPECT OUTER MIRROR SWITCH ASSEMBLY





(a) Remove the outer mirror switch assembly.
(b) Measure the resistance between the wire harness connectors.
Vertical and horizontal operation:





Left or right side operation:






NG -- REPLACE OUTER MIRROR SWITCH ASSEMBLY
OK -- Continue to next step.

2. CHECK WIRE HARNESS (OUTER MIRROR SWITCH ASSEMBLY - INSTRUMENT PANEL J/B)





(a) Disconnect the D4 and D7 connectors.
(b) Measure the resistance between the wire harness connectors.
Standard resistance:






NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE
