OPTICAL SENSOR

OPTICAL SENSOR

Description

INFOID:0000000006179041

The optical sensor converts the outside brightness (lux) to voltage and transmits the optical sensor signal to

the BCM.

Component Function Check

INFOID:0000000006179042

1.

CHECK OPTICAL SENSOR SIGNAL BY CONSULT-III

CONSULT-III

1. Turn the ignition switch ON.
