OPTICAL SENSOR
OPTICAL SENSOR
Description
INFOID:0000000005259755
The optical sensor converts the outside brightness (lux) to voltage and transmits the optical sensor signal to
the BCM.
Component Function Check
INFOID:0000000005259756
1.
CHECK OPTICAL SENSOR SIGNAL BY CONSULT-III
CONSULT-III
1. Turn the ignition switch ON.
2. Select "OPTICAL SENSOR" of BCM (HEAD LAMP) DATA MONITOR item.
3. Turn the lighting switch to 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
.
Diagnosis Procedure
INFOID:0000000005259757
Regarding Wiring Diagram information, refer to
1.
CHECK OPTICAL SENSOR GROUND CIRCUIT
1. Turn the ignition switch OFF.
2. Disconnect BCM connector M18 and optical sensor connector
M145.
3. Check continuity between BCM harness connector M18 (A) ter-
minal 18 and optical sensor harness connector M145 (B) termi-
nal 3.
4. Check continuity between BCM harness connector M18 (A) ter-
minal 18 and ground.
Are continuity results as specified?
YES
>> GO TO 2
