Diagnosis Procedure

1.CHECK HEADLAMP (HI) OUTPUT VOLTAGE

CONSULT-III ACTIVE TEST

1. Turn ignition switch OFF.

2. Disconnect headlamp connector.

3. Turn ignition switch ON.

4. Select “EXTERNAL LAMPS” of IPDM E/R active test item.

5. With operating the test items, check voltage between IPDM E/R harness connector and ground.

Is the inspection result normal? YES >> GO TO 2.

NO >> GO TO 3.

2.CHECK HEADLAMP (HI) OPEN CIRCUIT

1. Turn ignition switch OFF.

2. Disconnect IPDM E/R connector.

3. Check continuity between IPDM E/R harness connector and headlamp harness connector.

Is the inspection result normal? YES >> Replace headlamp bulb.

NO >> Repair or replace harness.

3.CHECK HEADLAMP (HI) FUSE

1. Turn ignition switch OFF.

2. Check that the following fuses are not fusing.

Is the inspection result normal? YES >> Replace IPDM E/R.

NO >> GO TO 4.

4.CHECK HEADLAMP HIGH (HI) SHORT CIRCUIT

1. Disconnect IPDM E/R connector.

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

Is the inspection result normal? YES >> Replace the fuse. (Replace IPDM E/R if the fuse is fusing again.) NO >> Repair or replace harness. And then replace the fuse.
