HEADLAMP (LO) CIRCUIT
Component Function CheckINFOID:0000000003773682
1.CHECK HEADLAMP (LO) OPERATION
IPDM E/R AUTO ACTIVE TEST
1. Activate IPDM E/R auto active test. Refer to PCS-11, "
Diagnosis Description".
2. Check that the headlamp is turned ON.
CONSULT-III ACTIVE TEST
1. Select “EXTERNAL LAMPS” of IPDM E/R active test item.
2. With operating the test items, check that the headlamp (LO) is turned ON.
Is the headlamp (LO) turned ON?
YES >> Headlamp (LO) is normal.
NO >> Refer to EXL-229, "
Diagnosis Procedure".
Diagnosis ProcedureINFOID:0000000003773683
1.CHECK HEADLAMP (LO) OUTPUT VOLTAGE
CONSULT-III ACTIVE TEST
1. Turn the ignition switch OFF.
2. Disconnect the front combination lamp connector.
3. Turn the ignition switch ON.
4. Select “EXTERNAL LAMPS” of IPDM E/R active test item.
5. With operating the test items, check the voltage between the IPDM E/R harness connector and the
ground.
Is the measurement value normal?
YES >> GO TO 2.
NO >> GO TO 3.
2.CHECK HEADLAMP (LO) OPEN CIRCUIT
1. Turn the ignition switch OFF.
2. Disconnect IPDM E/R connector.
3. Check continuity between the IPDM E/R harness connector and the front combination lamp harness con-
nector.Lo : Headlamp (LO) ON

HEADLAMP (LO) CIRCUIT
Does continuity exist?
YES >> GO TO 5.
NO >> Repair the harnesses or connectors.
3.CHECK HEADLAMP (LO) FUSE
1. Turn the ignition switch OFF.
2. Check that the following fuses are not fusing.
Is the fuse fusing?
YES >> GO TO 4.
NO >> Replace IPDM E/R.
4.CHECK HEADLAMP (LO) SHORT CIRCUIT
1. Disconnect IPDM E/R connector.
2. Check continuity between the IPDM E/R harness connector and the ground.
Does continuity exist?
YES >> Repair the harnesses or connectors. And then replace the fuse.
NO >> Replace the fuse. (Replace IPDM E/R if the fuse is fusing again.)
5.CHECK HEADLAMP (LO) GROUND OPEN CIRCUIT
1. Turn the ignition switch OFF.
2. Disconnect the front combination lamp connector.
3. Check continuity between the front combination lamp harness connector and ground.
Does continuity exist?
YES >> Replace the headlamp (LO) bulb. (Bulb socket is abnormally.)
NO >> Repair the harnesses or connectors.

OPTICAL SENSOR
OPTICAL SENSOR
DescriptionINFOID:0000000003894326
Optical sensor converts the outside brightness (lux) to voltage and transmits the optical sensor signal to BCM.
Component Function CheckINFOID:0000000003894327
1.CHECK OPTICAL SENSOR SIGNAL BY CONSULT-III
CONSULT-III DATA MONITOR
1. Turn the ignition switch ON.
2. Select "OPTICAL SENSOR" of BCM (HEADLAMP) data monitor item.
3. Turn the lighting switch AUTO.
4. With the optical sensor illuminating, check the monitor status.
*: Illuminates the optical sensor. The value may be less than the standard value if brightness is weak.
Is the item status normal?
YES >> Optical sensor is normal.
NO >> Refer to EXL-238, "
Diagnosis Procedure".
Diagnosis ProcedureINFOID:0000000003894328
1.CHECK OPTICAL SENSOR POWER SUPPLY INPUT
1. Turn the ignition switch ON.
2. Turn the lighting switch AUTO.
3. Check the voltage between the optical sensor harness connector and the ground.
Is the measurement value normal?
YES >> GO TO 2.
NO >> GO TO 4.
2.CHECK OPTICAL SENSOR GROUND INPUT
Check the voltage between the optical sensor harness connector and the ground.
Is the measurement value normal?
YES >> GO TO 3.
NO >> GO TO 6.
3.CHECK OPTICAL SENSOR SIGNAL OUTPUT
