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.

AFS OPERATION
When The Steering Wheel Is Turned To The Left
Swivel motor driving signal (1-phase) is transmitted when the steer-
ing wheel is turned to left approximately more than 10* degrees
(predetermined), with vehicle speed at approximately 25 km/h (15.5
MPH) or more, headlamps (HIGH/LOW) illuminated, AFS switch ON
and the engine running and the A/T select lever in any position
except range P or R.
* : Slightly different from the case when it is turned to the right.
Swivel motor driving signal (1-phase) is sent
to front combination lamp LH terminal 17
through AFS control unit terminal 15,
to AFS control unit terminal 38
through front combination lamp LH terminal 21.
And swivel motor driving signal (2-phase) is sent:
to front combination lamp LH terminal 16
through AFS control unit terminal 17,
to AFS control unit terminal 36
through front combination lamp LH terminal 20.
Swivel position sensor detects swivel angle during ignition switch ON, and transmits swivel position sensor
signals to the AFS control unit:
When ignition switch is turn to ON position, power is supplied
to front combination lamp LH terminal 15
through AFS control unit terminal 24.
When ignition switch is turn to ON position, swivel position sensor signal input is supplied
to AFS control unit terminal 29
through front combination lamp LH terminal 14.
Ground is supplied
to front combination lamp LH terminal 19
through AFS control unit terminal 27.
The low beam headlamp LH starts to swivel to the left.
The swivel motor driving signals are blocked and the swivel motion stops when the steering angle reaches
approximately more than 80 degrees (predetermined). The low beam headlamp will not swivel any further no
matter how further left. As the steering wheel is turned back to the right, the swivel motor driving signals (both
1-phase and 2-phase) will be reversed, causing low beam headlamp LH to start swiveling to the right. When
steering angle becomes smaller than predetermined value, the low beam headlamp is set in the straight-
ahead position, swivel motor driving signals are blocked and low beam headlamps stop swiveling.
When The Steering Wheel Is Turned To The Right
Swivel motor driving signal (1-phase) is transmitted when the steer-
ing wheel is turned to right approximately more than 10* degrees
(predetermined), with headlamps (HIGH/LOW) illuminated, AFS
switch ON, the engine running and the A/T select lever in any posi-
tion except range P or R.
* : Slightly different from the case when it is turned to the left.
Swivel motor driving signal (1-phase) is sent
to front combination lamp RH terminal 16
through AFS control unit terminal 34,
to AFS control unit terminal 11
through front combination lamp RH terminal 20.
And swivel motor driving signal (2-phase) is sent
to front combination lamp RH terminal 17
through AFS control unit terminal 32,
to AFS control unit terminal 13

The low beam headlamp RH starts to swivel to the right.
The swivel motor driving signals are blocked and the swivel motion stops when the steering angle reaches
approximately more than 80 degrees (predetermined). The low beam headlamp will not swivel any further no
matter how further right. As the steering wheel is turned back to the left, the swivel motor driving signals (both
1-phase and 2-phase) will be reversed, causing low beam headlamp RH to start swiveling to the left. When
steering angle becomes smaller than predetermined value, the low beam headlamp is set in the straight-
ahead position, swivel motor driving signals are blocked and low beam headlamps stop swiveling.
AFS OFF INDICATOR OPERATION
In response to the state of control, AFS control unit switches com-
mands of AFS off indicator signal sent to unified meter and A/C amp.
via CAN communication; and then turns on/off or blinks AFS off indi-
cator lamp built in the combination meter depending on the following
condition.
Bulb check operation
AFS off indicator lamp is turned off after illuminating for one sec-
ond as a bulb check for AFS off indicator lamp when turn ignition
switch ON is detected.
NOTE:
AFS off indicator lamp is turned off without a lapse of one sec-
ond when start of the engine is detected.
AFS switch operation
AFS off indicator lamp is illuminated while AFS switch is OFF.
AFS off indicator lamp is turned off while AFS switch is ON.
System warning operation
AFS off indicator lamp illuminates at intervals of approximately one second when AFS control unit detects
any specific DTC (diagnosis trouble code), or when unified meter and A/C amp. cannot receive AFS off
indicator signals.
NOTE:
Unified meter and A/C amp. transmits a command to combination meter to blink AFS off indicator lamp
when they cannot receive AFS off indicator signal.
SWIVEL ACTUATOR INITIALIZATION
AFS control unit performs swivel operation to initialize swivel actuator when start of the engine is detected.
Straight-ahead position of low beam headlamps is adjusted by turning low beam headlamps to outside vehicle
with specified swivel angle after turning it to the center of vehicle and making sure that it reaches the stopper.
Swivel actuator initialization shall be performed every time when start of the engine is detected.
