●

Parking, license plate, side marker and tail lamps and 
headlamps will not illuminate when outside of the vehicle 
becomes dark. (Lighting switch 1ST position and 2ND posi-
tion operate normally.) 

●

Parking, license plate, side marker and tail lamps and 
headlamp will not go out when outside of the vehicle 
becomes light. (Lighting switch 1ST position and 2ND posi-
tion operate normally.)

●

Headlamps go out when outside of the vehicle becomes 
light, but parking lamps stay on.

Optical sensor System Inspection

NKS000HD

1. 

CHECK OPTICAL SENSOR INPUT SIGNAL 

With CONSULT-II

Select “BCM” on CONSULT-II. With “HEAD LAMP” data monitor,
make sure “OPTICAL SENSOR”, and check difference in voltage
when the optical sensor is illuminated and not illuminated.

CAUTION:

Optical sensor must be securely subjected to work lamp light. If
optical sensor is insufficiently illuminated, the measured value
may not satisfy the standard.

Without CONSULT-II

1.

Turn ignition switch ON.

2.

Check voltage between BCM harness connector M1 terminal 14
and ground.

CAUTION:

Optical sensor must be securely subjected to work lamp light. If
optical sensor is insufficiently illuminated, the measured value
may not satisfy the standard.

>> GO TO 2.

2. 

CHECK OPTICAL SENSOR POWER SUPPLY CIRCUIT 

1.

Turn ignition switch OFF.

2.

Disconnect BCM connector and optical sensor connector.

3.

Check continuity (open circuit) between BCM harness connector
M1 terminal 17 and optical sensor harness connector M63 ter-
minal 1.

4.

Check continuity (short circuit) between BCM harness connector
M1 terminal 17 and ground.
