HEADLAMP AUTO AIMING
Headlamp auto aiming control automatically corrects vertical deviation of light axis that is brought by the
change of vehicle height with changing number of passenger and laden weight, and relieves dazzle to oncom-
ing vehicles.
AFS control unit determines the current vehicle conditions by each received signals, and sends commands to
the low beam headlamps to auto aiming. With the headlamps (HIGH/LOW) illuminated and engine running,
the low beam headlamps are operative by AFS control unit commands.
The height sensor is located on the left side of the rear suspension member and detects rear vehicle height
change by sensing the displacement of the rear suspension arm. And transmits a height sensor signal to the
AFS control unit.
With reference to the rear vehicle height under the empty condition, light axis of low beam with low rear vehi-
cle height is relatively higher than that with the empty condition. AFS control unit switches drive signal corrects
height of low beam axis to maintain height of light axis with empty condition.
Light axis of low beam with high rear vehicle height is relatively lower than that with empty condition. Light axis
of low beam with empty condition is set as upper limit of headlamp auto aiming control operation. Control to
correct deviation is not performed when light axis of low beam gets relatively higher than that with empty con-
dition. Timing of control is switched in accordance with driving conditions.
Headlamp auto aiming operation
*1: Included high beam illuminated
*2: Control timing of drive signal is switched by vehicle speed and accelerating/decelerating vehicle.
*3: Control is performed without regard to the condition of AFS switch. Headlamp auto aiming control function cannot be cancelled.
OUTLINE
Power is supplied
When the ignition switch is ON or START position, power is supplied
through 10A fuse [No.12, located in fuse block (J/B)]
to AFS control unit terminal 1
to front combination lamp LH and RH terminal 13
to AFS switch terminal 1.
Ground is supplied
to AFS control unit terminal 25
through grounds M16 and M70,
to front combination lamp LH and RH terminal 11
through grounds E22 and E43.

AFS SWITCH
AFS switch transmits state of ON/OFF as AFS switch signals to AFS
control unit.
AFS control unit performs AFS operation when AFS switch is
ON and turns off AFS off indicator lamp.
AFS control unit does not perform AFS operation when AFS
switch is OFF, and turns on AFS off indicator lamp.
HEIGHT SENSOR
The height sensor is located on the left side of the rear suspension
member and detects rear vehicle height change by sensing the dis-
placement of the rear suspension arm. And transmits a height sen-
sor signal to the AFS control unit.
STEERING ANGLE SENSOR
The steering angle sensor is located combination switch and detects
steering angle. And transmits a steering angle sensor signal to the
AFS control unit.
IPDM E/R
IPDM E/R detects ON/OFF state of low beam headlamps. It transmits a low beam state signal to the AFS con-
trol unit.
ECM
ECM transmits an engine speed signal to the AFS control unit.
TCM
TCM transmits an A/T position indicator signal to the AFS control unit.
UNIFIED METER AND A/C AMP.
Unified meter and A/C amp. transmits vehicle speed signals to the AFS control unit.
Unified meter and A/C amp. transmits AFS off indicator signals received from the AFS control unit to the
combination meter.
COMBINATION METER
Combination meter turns on/off or blinks built-in AFS off indicator lamp depending on AFS off indicator signal
received from unified meter and A/C amp.

WORK SUPPORT (STEERING ANGLE SENSOR ADJUSTMENT)
Work Support Item List
CAUTION:
Never use this function but on VDC side.
Notes on Steering Angle Sensor (Neutral Point) Adjustment
Be sure to adjust steering angle sensor neutral point before driving if any of the following has been
removed/installed or replaced: Steering angle sensor; Steering system part, Suspension system part.
On vehicle with VDC, perform steering angle sensor neutral point adjustment only on VDC side. Never
perform the adjustment on ADAPTIVE LIGHT side as this may lead to VDC malfunctions. If the adjust-
ment has been performed on AFS side, readjust on VDC side. For steering angle sensor neutral point
adjustment procedures on VDC side, refer to BRC-6, "
Adjustment of Steering Angle Sensor Neutral Posi-
tion" in “ON-VEHICLE SERVICE”.
When replaced steering angle sensor, AFS control unit detects “DTC B2515 ST ANG SEN SIG”. Delete
the malfunction history after adjust steering angle sensor on VDC side.
Steering angle sensor neutral point adjustment should be performed using CONSULT-II. (The adjustment
will not be possible without CONSULT-II.)
Operation Procedure
Refer to BRC-6, "Adjustment of Steering Angle Sensor Neutral Position" in BRC section.
WORK SUPPORT (LEVELIZER ADJUSTMENT)
Work Support Item List
Operation Procedure
1. Set the vehicle in unload condition. (Removal all loads in driver, passenger and trunk rooms.)
2. Touch “ADAPTIVE LIGHT” on “SELECT SYSTEM” screen.
3. Touch “WORK SUPPORT” on “SELECT DIAG MODE” screen.
4. Touch “LEVELIZER ADJUSTMENT”.
5. Touch “START”.
6. “ADJUSTMENT COMPLETE” will be displayed.
CAUTION:
When “CAN NOT BE TESTED” is displayed, AFS control unit stops levelizer adjustment as it
detected the change of height sensor signal. AFS control unit detects “DTC B2519 LEVELIZER
CALIB”.
Turn ignition switch OFF not to change the vehicle height. Then turn ignition switch ON and per-
form levelizer adjustment again.
When “ADJUSTMENT COMPLETE” is displayed, and “NO DTC IS DETECTED” is displayed on
self-diagnosis results, levelizer adjustment is completed.
When “ADJUSTMENT COMPLETE” is displayed, and “B2514 HI SEN UNUSUAL” is displayed on
self-diagnosis results, refer to LT-174, "
DTC B2514 HI SEN UNUSUAL RR" .
