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

for Preparation Click here


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).

CHECK AND REPLACE OUTER MIRROR CONTROL ECU 

2.INSPECT OUTER MIRROR SWITCH


    B069211E01

  1. Remove the outer mirror switch.

  1. Measure the resistance according to the value(s) in the table below when the switch is operated.

    Standard resistance:
    Mirror switch:
    Tester Connection
    		Switch Position
    		Specified Condition
    2 - 3
    		OFF
    		10 kΩ or higher
    UP
    		225 to 275 Ω
    DOWN
    		437 to 503 Ω
    LEFT
    		744 to 856 Ω
    RIGHT
    		437 to 503 Ω
    1 - 2
    		L
    		90 to 110 Ω
    R
    		10 Ω or less



NG
REPLACE OUTER MIRROR SWITCH
OK


3.CHECK WIRE HARNESS (OUTER MIRROR SWITCH - BODY ECU)


    B069724E02

  1. Disconnect the R5 and B6 connectors.

  1. Measure the resistance according to the value(s) in the table below.

    Standard resistance:
    Tester Connection
    		Condition
    		Specified Condition
    R5-3 (M+) - B6-11 (MIRB)
    		Always
    		Below 1 Ω
    R5-1 (MSW) - B6-12 (MIRS)
    		Always
    		Below 1 Ω
    R5-2 (E1) - B6-3 (MIRE)
    		Always
    		Below 1 Ω
    R5-3 (M+) - Body ground
    		Always
    		10 kΩ or higher
    R5-1 (MSW) - Body ground
    		Always
    		10 kΩ or higher
    R5-2 (E1) - Body ground
    		Always
    		10 kΩ or higher



NG
