1.

CHECK OPTICAL SENSOR SIGNAL BY CONSULT

CONSULT DATA MONITOR

1.

Turn ignition switch ON.

2.

Select “OPTISEN (DTCT)” of BCM (HEADLAMP) data monitor item.

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-193, "Diagnosis Procedure"

.
