HEADLAMP LEVELIZER CIRCUIT
HEADLAMP LEVELIZER CIRCUIT
DescriptionINFOID:0000000003774349
The headlamp levelizer adjusts the headlamp light axis upward and downward with the aiming motor inte-
grated in the front combination lamp.
Component Function CheckINFOID:0000000003774350
1.CHECK HEADLAMP LEVELIZER OPERATION
CONSULT-III ACTIVE TEST
1. Start the engine.
2. Turn the lighting switch 2ND.
3. Select “LAMP TEST” of HEADLAMP LEVELIZER active test item.
4. With operating the test item, check the light axis operation.
Is the operation normal?
YES >> Headlamp levelizer circuit is normal.
NO >> Refer to EXL-60, "
Diagnosis Procedure".
Diagnosis ProcedureINFOID:0000000003774351
1.CHECK AIMING MOTOR DRIVE SIGNAL OUTPUT
CONSULT-III ACTIVE TEST
1. Start the engine.
2. Turn the light switch 2ND.
3. Select “LAMP TEST” of HEADLAMP LEVELIZER active test item.
4. With operating the test items, check the voltage between the auto levelizer control unit harness connector
and the ground.
Is the measurement value normal?
YES >> GO TO 2.
Fixed at 0 V>>GO TO 3.
Fixed at battery voltage>>GO TO 4.
2.CHECK AIMING MOTOR DRIVE OPEN CIRCUIT
1. Turn the ignition switch OFF.
2. Disconnect auto levelizer control unit connector and headlamp aiming motor connector.
3. Check continuity between auto levelizer control unit harness connector and the headlamp aiming motor
harness connector.

OPTICAL SENSOR
DescriptionINFOID:0000000003773573
Optical sensor converts the outside brightness (lux) to voltage and transmits the optical sensor signal to BCM.
Component Function CheckINFOID:0000000003773574
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-69, "
Diagnosis Procedure".
Diagnosis ProcedureINFOID:0000000003773575
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
