Phenomenon Malfunction system and reference

Parking lamps and headlamps will not illuminate when outside
of the vehicle becomes dark. (Lighting switch 1ST position and
2ND position operate normally.)

Parking lamps and headlamp will not go out when outside of the
vehicle becomes light. (Lighting switch 1ST position and 2ND
position operate normally.)

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

Refer to LT-128, "WORK SUPPORT" .

Refer to LT-131, "Lighting Switch Inspection" .

Refer to LT-131, "Optical Sensor System Inspection" .
If above systems are normal, replace BCM.
Parking lamps illuminate when outside of the vehicle becomes

2ND position operate normally.)

Refer to LT-128, "WORK SUPPORT" .

Refer to LT-131, "Optical Sensor System Inspection" .
If above systems are normal, replace BCM.
With the ignition key in ACC position, headlamps, clearance
lamps, tail lamps, etc. will not go out when the driver's door is
opened.

Refer toBL-94, "Check Door Switch" .
If above system is normal, replace BCM.
Auto light adjustment system will not operate. (Lighting switch

1. CHECK LIGHTING SWITCH INPUT SIGNAL
With CONSULT-II
1. Select “BCM” on CONSULT-II, and select “HEAD LAMP” on
“SELECT TEST ITEM” screen.
2. Select “DATA MONITOR” on “SELECT DIAG MODE” screen,
and make sure “AUTO LIGHT SW” turns ON–OFF linked with
operation of lighting switch.
Without CONSULT-II
Refer to LT- 2 3 9 , "
Combination Switch Inspection" .

Optical Sensor System InspectionNKS003QC
1. CHECK OPTICAL SENSOR INPUT SIGNAL
With CONSULT-II
1. Select “BCM” on CONSULT-II, and select “HEAD LAMP” on
“SELECT TEST ITEM” screen.
2. Select “DATA MONITOR” on “SELECT DIAG MODE” screen.
On “OPTICAL SENSOR”, check difference in the voltage when
optical sensor is illuminated and not illuminated.
CAUTION:
Optical sensor must be securely subjected to work lamp light. If the 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 and ground.
CAUTION:
Optical sensor must be securely subjected to work lamp light. If the optical sensor is insufficiently
illuminated, the measured value may not satisfy the standard.
