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 multiplex network body ECU. Then, the outer mirror control ECU activates the mirror motor to move the mirror UP, DOWN, RIGHT and LEFT 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).

INSPECTION PROCEDURE

PROCEDURE

1. READ VALUE USING INTELLIGENT TESTER
(a) Check the DATA LIST for proper function of the outer mirror switches.

BODY





NG -- INSPECT OUTER MIRROR SWITCH
OK -- CHECK AND REPLACE OUTER MIRROR CONTROL ECU
2. INSPECT OUTER MIRROR SWITCH





(a) Remove the outer mirror switch.
(b) Measure the resistance according to the value(s) in the table below when the switch is operated.
Standard resistance:






NG -- REPLACE OUTER MIRROR SWITCH
OK -- Continue to next step.
3. CHECK WIRE HARNESS (OUTER MIRROR SWITCH - BODY ECU)





(a) Disconnect the R5 and B4 connectors.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance:






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