Mirror Retract Switch Circuit

MIRROR: POWER MIRROR CONTROL SYSTEM: Mirror Retract Switch Circuit
- Mirror Retract Switch Circuit

DESCRIPTION

This circuit detects the conditions of the mirror retract switch.

The operating condition of the mirror retract switch is input by the driver side junction block ECU and the input signals are sent to the multiplex network door ECU front LH or RH (driver or passenger door ECU).

INSEPCTION PROCEDURE

PROCEDURE

1. READ VALUE USING TECHSTREAM (MIRROR RETRACT SWITCH)

(a) Check the Data List for proper functioning of the mirror retract switch.

Body No. 3:





OK:

On Techstream screen, each item changes between ON and OFF according to above chart.

OK -- PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE
NG -- Continue to next step.

2. INSPECT OUTER MIRROR SWITCH ASSEMBLY (MIRROR RETRACT SWITCH)





(a) Measure the resistance of the switch.

Standard resistance:





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

3. CHECK WIRE HARNESS (OUTER MIRROR SWITCH ASSEMBLY [MIRROR RETRACT SWITCH] - DRIVER SIDE JUNCTION BLOCK ECU AND BODY GROUND)





(a) Disconnect the M4 switch connector.

(b) Disconnect the D5 ECU connector.

(c) Measure the resistance of the wire harness side connectors.

Standard resistance:





NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR

OK -- REPLACE DRIVER SIDE JUNCTION BLOCK (DRIVER SIDE JUNCTION BLOCK ECU)
