ACTIVE TEST
Operation Procedure
1. Start the engine. (Swivel actuator is initialized.)
2. Touch “ADAPTIVE LIGHT” on “SELECT SYSTEM” screen.
3. Touch “ACTIVE TEST” on “SELECT DIAG MODE” screen.
4. Touch “LOW BEAM TEST RIGHT”, “LOW BEAM TEST LEFT”, or “LEVELIZER TEST” on “SELECT TEST
ITEM” screen.
CAUTION:
Can be tested only when swivel actuator initialization is completed. If initialization is not com-
pleted, “RETRY COMMAND” is displayed and cannot be tested.

LOW BEAM TEST RIGHT
Low beam headlamp (right) can be operated to swivel angle
0° by touching “ORIGIN”, and to maximum angle by “PEAK”.

LOW BEAM TEST LEFT
Low beam headlamp (left) can be operated to swivel angle 0°
by touching “ORIGIN”, and to maximum angle by “PEAK”.

LEVELIZER TEST
Aiming motor drive signal can be changed to approx. 85%
(ratio to IGN power supply) by touching “ORIGIN”, and to
approx. 15% by “PEAK”. That angles headlamp LO up and
down.
5. During the operation check, touching “BACK” deactivates the operation.

1. CHECK SWIVEL ACTUATOR
1. Start engine and turn lighting switch to 2ND position.
2. Select “ADAPTIVE LIGHT” on CONSULT-II. Select “ACTIVE
TEST” on “SELECT DIAG MODE” screen.
3. Select “LOW BEAM TEST RIGHT” or “LOW BEAM TEST LEFT”
on “SELECT TEST ITEM” screen.
4. Touch “ORIGIN–FAST/SLOW” and “PEAK–FAST/SLOW”
screen.
5. Make sure of swivel operation.
OK or NG
OK >> GO TO 2.

When interference or poor fitment is found, perform aiming adjustment. Refer to LT- 7 2 , "Aiming
Adjustment" . If it is normal, replace headlamp. Refer to LT- 1 9 1 , "Removal and Installation of
Front Combination Lamp" .

When the operation range is irregular, perform aiming adjustment. Refer to LT- 7 2 , "Aiming
Adjustment" . If it is normal, GO TO 3.
2. CHECK STEERING ANGLE SENSOR
Check “STR ANGLE SIG” in “Data Monitor” when driving straight
and steering turn 90° to right or left.
OK or NG
OK >> GO TO 3.
NG >>

When steering is out of range while driving straight, perform steering angle sensor adjustment.
Refer to BRC-6, "
Adjustment of Steering Angle Sensor Neutral Position" in “ON-VEHICLE
SERVICE”.

When the function is normal while driving straight but the displayed value is different from
actual steering position with turning to right or left, replace steering angle sensor. Refer to LT-
191, "Removal and Installation of Steering Angle Sensor" .

Aiming AdjustmentNKS003RH
The fog lamp is a semi-sealed beam type which uses a replaceable halogen bulb. Before performing aiming
adjustment, make sure of the following.

Keep all tires inflated to correct pressure.

Place vehicle on level ground.
Adjust aiming in the vertical direction by turning the adjusting screw.
1. Set the distance between the screen and the center of fog lamp
lens as shown.
2. Turn front fog lamps ON.
3. Adjust front fog lamps using adjusting screw so that the top edge
of the high intensity zone is in the figure.
When performing adjustment, if necessary, cover the headlamps
and opposite fog lamp.
