OPTICAL SENSOR

Description

INFOID:0000000009478483

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

the BCM.

Diagnosis Procedure

INFOID:0000000009478484

Regarding Wiring Diagram information, refer to 

EXL-84, "Wiring Diagram"

.

1.

CHECK OPTICAL SENSOR GROUND CIRCUIT

1. Turn the ignition switch OFF.

2. Disconnect BCM connector M18 and optical sensor connector M14.

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. Refer to 

EXL-149, "Removal and Installation"

.

NO

>> Repair harness or connector.
