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.

Refer to LT- 6 6 , "WORK SUPPORT" .

Refer to LT- 6 9 , "Lighting Switch Inspection" .

Refer to LT- 7 0 , "Optical sensor System Inspection" .

1. CHECK OPTICAL SENSOR INPUT SIGNAL
With CONSULT-II
Select “BCM” on CONSULT-II. With “HEAD LAMP” data monitor,
make sure “OPTICAL SENSOR”, check difference in the voltage
when auto light sensor is illuminated and not illuminated.
CAUTION:

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 M3 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.

NG >> 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 M3 terminal 17 and optical sensor harness connector M37 ter-
minal 1.
4. Check continuity (short circuit) between BCM harness connector M3 terminal 17 and ground.
