INSPECTION PROCEDURE

PROCEDURE

1. CHECK WIRE HARNESS (RELAY - BATTERY AND BODY GROUND)





(a) Disconnect the A5 relay connector.

(b) Measure the voltage of the wire harness side connector.

Standard voltage:





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

2. INSPECT HEADLIGHT CLEANER MOTOR AND PUMP ASSEMBLY





(a) Remove the headlight cleaner motor and pump.

(b) Apply battery voltage to the headlight cleaner motor and check the operation of the headlight cleaner motor.

OK:





NG -- REPLACE HEADLIGHT CLEANER MOTOR AND PUMP ASSEMBLY
OK -- Continue to next step.

3. CHECK WIRE HARNESS (MOTOR - RELAY AND BATTERY)





(a) Disconnect the A3 motor connector.

(b) Disconnect the A5 relay connector.

(c) Measure the voltage of the wire harness side connector.

Standard voltage:





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

Standard resistance:





NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR

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