INSEPCTION PROCEDURE

PROCEDURE

1. INSPECT OUTER MIRROR SWITCH ASSEMBLY (HEADLIGHT CLEANER SWITCH)





(a) Remove the outer mirror switch.

(b) Measure the resistance of the switch.

Standard resistance:





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

2. CHECK WIRE HARNESS (SWITCH - ECU AND RELAY)





(a) Disconnect the M4 switch connector.

(b) Disconnect the D5 ECU connector.

(c) Disconnect the H3 relay connector.

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

Standard resistance:





NG -- REPAIR OR REPLACE HARNESS AND CONNECTOR
OK -- Continue to next step.

3. CHECK WIRE HARNESS (ECU - RELAY)





(a) Disconnect the D2 ECU connector.

(b) Disconnect the H3 relay connector.

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

Standard resistance:





NG -- REPAIR OR REPLACE HARNESS AND CONNECTOR

OK -- PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE
