RH

>> GO TO 6.

LH

>> GO TO 8.

6.

CHECK HEADLAMP HI (RH) GROUND OPEN CIRCUIT-1

1.

Remove daytime running light relay.

2.

Check continuity between daytime running light relay harness connector and headlamp high RH harness
connector.

Is the inspection result normal?

YES

>> GO TO 7.

NO

>> Repair or replace harness.

7.

CHECK HEADLAMP HI (RH) GROUND OPEN CIRCUIT-2

Check continuity between daytime running light relay harness connector and ground.

Is the inspection result normal?

YES

>> Replace headlamp (HI) bulb. (Bulb socket is abnormal.)

NO

>> Repair or replace harness.

8.

CHECK HEADLAMP HI (LH) GROUND OPEN CIRCUIT

Check continuity between headlamp high LH harness connector and ground.

Is the inspection result normal?

YES

>> Replace headlamp (HI) bulb. (Bulb socket is abnormal.)

NO

>> Repair or replace harness.
