Lighting Switch Inspection

EKS00FVC

1.

CHECK LIGHTING SWITCH INPUT SIGNAL

With CONSULT-II

Select "BCM" on CONSULT-II. With "HEAD LAMP" data monitor,
make sure "AUTO LIGHT SW" turns ON-OFF linked with operation
of lighting switch.

Without CONSULT-II

Refer to

LT-75, "Combination Switch Inspection"

.

OK or NG

OK

>> Inspection End.

NG

>> Check lighting switch. Refer to

LT-75, "Combination

Switch Inspection"

.

Optical Sensor System Inspection

EKS00FVD

1.

CHECK OPTICAL SENSOR INPUT SIGNAL

With CONSULT-II

Select "BCM" on CONSULT-II. With "OPTICAL SENSOR" data mon-
itor, check difference in the voltage when the optical sensor is illumi-
nated and not illuminated.

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

Without CONSULT-II

GO TO 2.

OK or NG

OK

>> Inspection End.

NG

>> GO TO 2.

2.

CHECK OPTICAL SENSOR SIGNAL GROUND CIRCUIT

1.

Turn ignition switch OFF.

2.

Disconnect BCM connector and optical sensor connector.

3.

Check continuity (open circuit) between BCM harness connector
M18 terminal 18 and optical sensor harness connector M145
terminal 3.

4.

Check continuity (short circuit) between BCM harness connector
M18 terminal 18 and ground.

OK or NG

OK

>> GO TO 3.

NG

>> Repair harness or connector.
