OPTICAL SENSOR
Description
INFOID:0000000003756986
Optical sensor converts the outside brightness (lux) to voltage and transmits the optical sensor signal to BCM.
Component Function Check
INFOID:0000000003756987
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-252, "Diagnosis Procedure"
.
Diagnosis Procedure
INFOID:0000000003756988
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.

CHECK OPTICAL SENSOR SIGNAL OUTPUT
With illuminating the optical sensor, check the voltage between the optical sensor harness connector and the
ground.
*: Illuminate the optical sensor. The value may be less than the standard if brightness is weak.
Is the measurement value normal?
YES
>> GO TO 7.
NO
>> Replace the optical sensor.
4.
CHECK OPTICAL SENSOR OPEN CIRCUIT
1.
Turn the ignition switch OFF.
2.
Disconnect the optical sensor connector and BCM connector.
3.
Check continuity between the optical sensor harness connector and the BCM harness connector.
Does continuity exist?
YES
>> GO TO 5.
NO
>> Repair the harnesses or connectors.
5.
CHECK OPTICAL SENSOR SHORT CIRCUIT
Check the continuity between the optical sensor harness connector and the ground.
Does continuity exist?
YES
>> Repair the harnesses or connectors.
NO
>> Replace BCM.
6.
CHECK OPTICAL SENSOR GROUND OPEN CIRCUIT
1.
Turn the ignition switch OFF.
2.
Disconnect the optical sensor connector and BCM connector.
3.
Check continuity between the optical sensor harness connector and the BCM harness connector.
Does continuity exist?
YES
>> Replace BCM.
NO
>> Repair the harnesses or connectors.
