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.

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.
