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.
NG >>
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" .

3. CHECK SWIVEL ACTUATOR AND AFS CONTROL UNIT
Check “SWVL SEN RH/LH” and “SWVL ANGLE RH/LH” in “Data
Monitor” with steering turning to right or left under swivel operative
condition.
NOTE:
The angle can be slightly different between the displayed value on “SWVL SEN” and
that on “SWVL ANGLE” even when AFS operation is normal.
OK or NG
OK >> AFS function is normal.
NG >>
When the difference is 4.5° or more between the displayed value on “SWVL ANGLE” and that
on “SWVL SEN”, replace headlamp.
When the displayed angle on “SWVL ANGLE” is irregular, replace AFS control unit.

position. (Remove all loads in driver, passenger and trunk rooms.)
OK or NG
OK >> GO TO 3.
NG >> Perform LEVELIZER ADJUSTMENT. Refer to LT- 1 5 2 ,
"WORK SUPPORT (LEVELIZER ADJUSTMENT)" .
3. PERFORM STATE LEVELIZER ADJUSTMENT 2
Check if “LEV ACTR VLTG” changes approx. 3 seconds after lower-
ing vehicle height as low as approx. −0.5V from the value of “HI SEN
OTP RR” in “Data Monitor” at unloaded vehicle position. (Remove all
loads in driver, passenger and trunk rooms.)
OK or NG
OK >> GO TO 4.

4. CHECK HEIGHT SENSOR SIGNAL AND AIMING MOTOR DRIVE SIGNAL
Remove height sensor link bracket mounting nuts (rear stabilizer side). For details, refer to LT- 1 9 3 , "
Removal
and Installation of Height Sensor" . Change sensor angle from the basic point of sensor angle 0° (standard
position) and check “HI SEN OTP RR” and “LEV ACTR VLTG” of “Data Monitor”.
With 18-inch wheel
NOTE:
1. Reference value. The value can be different from that of sensor angle and HI SEN OTP RR of maximum/minimum angle of auto
aiming operation depending on LEVELIZER ADJUSTMENT state.
2. Reference value. Approx. −1.5 V from the LEVELIZER ADJUSTMENT value.
With 19-inch wheel
NOTE:
1. Reference value. The value can be different from that of sensor angle and HI SEN OTP RR of maximum/minimum angle of auto
aiming operation depending on LEVELIZER ADJUSTMENT state.
2. Reference value. Approx. −1.2 V from LEVELIZER ADJUSTMENT value.
OK or NG
OK >> Auto aiming operation function is normal.
NG >>
When approx. 4.5 V or 0.5 V is not displayed on “HI SEN OTP RR” screen with sensor angle
approx. 45° or −45°, check connector for connection, bend and loose fit. If it is normal, replace
height sensor. Refer to LT- 1 9 3 , "
Removal and Installation of Height Sensor" .
When “HI SEN OTP RR” value is normal but “LEV ACTR VLTG” value differs from maximum/
minimum angle of auto aiming operation, replace AFS control unit. Refer to LT- 1 9 2 , "
Removal
and Installation of AFS Control Unit" .
When “LEV ACTR VLTG” value is normal but operation range is irregular, check aiming motor
system circuit. Refer to LT- 1 8 8 , "
