Step 6. Check the wiring harness between A-25 
headlamp washer motor connector terminal No.2 
and body earth.

•

Check the earth wires for open circuit.

Q: Is the check result normal?

YES : 

The trouble can be an intermittent 

malfunction (Refer to GROUP 00 

−

 How to 

Cope with Intermittent Malfunction 

P.00-6

).

NO : 

Repair the wiring harness.

Step 7. Connector check: A-11X front-ECU 
connector

Q: Is the check result normal?

YES : 

Go to Step 8.

NO : 

Repair the connector.

Step 8. Measure the voltage at the A-11X 
front-ECU connector.

(1) Remove the front-ECU, and measure at the 

junction block side.

(2) Ignition switch: ACC

(3) Check the voltage between the A-11X front-ECU 

connector terminal No.3 and body earth.

OK: System voltage

Q: Is the check result normal?

YES : 

Go to Step 10.

NO : 

Go to Step 9.

Step 9. Check the wiring harness between A-11X 
front-ECU connector terminal No.3 and the 
fusible link (5).

•

Check the power supply line from the fusible link 
(5) for open circuit.

Q: Is the check result normal?

YES : 

The trouble can be an intermittent 

malfunction (Refer to GROUP 00

).

NO : 

Repair the wiring harness.

Step 10. Check the wiring harness between A-25 
headlamp washer motor connector terminal No.1 
and A-11X front-ECU connector terminal No.1.

•

Check the output line to headlamp washer motor 
for open circuit.

Q: Is the check result normal?

YES : 

Go to Step 11.

NO : 

Repair the wiring harness.

Step 11. Retest the system.

The headlamp washer should now work normally.

Q: Is the check result normal?
