Is the fusible link fusing?

YES

>> Replace the fusible link after repairing the applicable circuit.

NO

>> GO TO 2.

2.

CHECK HEADLAMP WASHER RELAY POWER SUPPLY

1.

Remove headlamp washer relay.

2.

Turn the ignition switch ON.

3.

Check voltage between headlamp washer harness connector and ground.

Is the measurement value normal?

YES

>> GO TO 3.

NO

>> Repair the harnesses or connectors.

3.

CHECK HEADLAMP WASHER RELAY

1.

Check headlamp washer relay. Refer to 

WW-38, "Component Inspection"

.

Is the headlamp washer relay normal?

Does continuity exist?

YES

>> GO TO 6.

NO

>> Repair the harnesses or connectors.

6.

CHECK HEADLAMP WASHER RELAY CONTROL SIGNAL SHORT CIRCUIT

Check continuity between IPDM E/R harness connector and ground.

Does continuity exist?

YES

>> Repair the harnesses or connectors.

NO

>> Replace IPDM E/R.

7.

CHECK HEADLAMP WASHER PUMP OPEN CIRCUIT

1.
