CHECK OPTICAL SENSOR SIGNAL BY CONSULT
CONSULT DATA MONITOR
1. Turn power switch ON.
2. Select “OPTISEN (DTCT)” in “Data Monitor” of “BCM (HEADLAMP)”.
3. Turn 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 inspection result normal?
YES
>> Optical sensor is normal.
NO
>> Refer to
EXL-246, "Diagnosis Procedure"
.
Diagnosis Procedure
INFOID:0000000010121467
Regarding Wiring Diagram information. Refer to
