INSPECTION PROCEDURE

PROCEDURE

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





(a) Disconnect the A5 headlight cleaner relay connector.
(b) Measure the voltage according to the value(s) in the table below.
Standard voltage:






NG -- CHECK WIRE HARNESS (HEADLIGHT CLEANER CONTROL RELAY - BODY GROUND)
OK -- PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE
2. CHECK WIRE HARNESS (HEADLIGHT CLEANER CONTROL RELAY - BODY GROUND)





(a) Disconnect the A5 headlight cleaner relay connector.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance:






NG -- REPAIR OR REPLACE HARNESS AND CONNECTOR
OK -- Continue to next step.
3. CHECK WIRE HARNESS (HEADLIGHT CLEANER CONTROL RELAY - BODY GROUND)





(a) Disconnect the A5 headlight cleaner relay connector.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance:






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





(a) Disconnect the connector from the headlight cleaner motor and pump assembly.
(b) Connect the positive (+) battery lead to terminal 1 of the headlight cleaner motor and pump assembly, and the negative (-) battery lead to terminal 2.
OK:
Operation sounds are heard.
NG -- REPLACE HEADLIGHT CLEANER MOTOR AND PUMP ASSEMBLY
OK -- Continue to next step.
5. CHECK WIRE HARNESS (HEADLIGHT CLEANER CONTROL RELAY - BODY GROUND)





(a) Disconnect the A5 headlight cleaner relay connector.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance:






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