Optical Sensor

OPTICAL SENSOR

Description

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


Diagnosis Procedure

Regarding Wiring Diagram information, Auto Light System.

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 and optical sensor harness connector.





4.Check continuity between BCM harness connector and ground.





Are continuity results as specified?
YES- GO TO 2
NO- Repair harness or connector.

2. CHECK OPTICAL SENSOR SIGNAL CIRCUIT

1.Check continuity between BCM harness connector and optical sensor harness connector.





2.Check continuity between BCM harness connector and ground.





Are the continuity results as specified?
YES- Replace the optical sensor. Service and Repair.
NO- Repair harness or connector.
