System Description
NKS00184
With the lighting switch in the first or second position, the headlamp aiming sensor detects change in the vehi-
cle height and transmits a corresponding signal to the headlamp aiming motors. The signal drives the head-
lamp aiming motors, which adjusts the low beam reflector of each headlamp to an angle appropriate for the
vehicle height.
When the vehicle is stationary, the motors move the reflectors if the vehicle height changes to a certain height
and the height is maintained for a predetermined period. When the vehicle is running (excluded when acceler-
ating/decelerating), the reflector angle is adjusted at predetermined intervals.

HEADLAMP AIMING CONTROL OPERATION
The headlamp aiming sensor is located on the right side of the rear suspension member and detects vehicle
height change by sensing the displacement of the suspension arm.
When the ignition switch is turned to the ON position, power is supplied
●
to headlamp aiming sensor terminal 2 and
●
to each headlamp aiming motor terminal 12
●
through 10A fuse [No. 1 located in fuse block (J/B) No.1].
At the same time, the vehicle height signal (voltage signal that corresponds to the vehicle height) is applied
●
to each headlamp aiming motor terminal 9
●
through headlamp aiming sensor terminal 7.
Ground is supplied
●
to each front combination lamp (headlamp aiming motor) terminal 10
●
through grounds E24, E42 and E62,
●
to headlamp aiming sensor terminal 1
●
through grounds B17 and B57.
And the voltage level of this signal is maintained.
When the lighting switch is placed in the 1ST or 2ND position, power is supplied
●
to headlamp aiming sensor terminal 6
●
through tail lamp relay terminal 7.
Ground is supplied
●
to headlamp aiming sensor terminal 1
●
through grounds B17 and B57.
to trigger the aiming control of the sensor.
When the stopped vehicle changes the height and keeps it for more than 15 seconds, the headlamp aiming
sensor outputs a headlamp aiming motor drive signal. And headlamp aiming sensor keeps supplying voltage
to headlamp aiming motor. (Voltage depends on the vehicle height.)
Upon reception of the headlamp aiming motor drive signal, both headlamp aiming motors cause the low beam
reflectors to move to the position commanded by the signal.
When the vehicle is running (excluded when accelerating/decelerating), the headlamp aiming sensor trans-
mits headlamp aiming motor drive signal to headlamp aiming motors at the predetermined intervals. The volt-
age level of every signal input is maintained unchanged until the next signal is input.
Upon reception of the headlamp aiming motor drive signal, both headlamp aiming motors cause the low beam
reflectors to move to the position commanded by the signal.
When the vehicle is accelerating or decelerating, the headlamp aiming sensor keeps the same headlamp aim-
ing motor drive signal voltage level rather than changing it, so that the low beam reflectors of both headlamps
do not operate.
When the lighting switch is turned OFF, the headlamp aiming sensor retains the headlamp aiming motor drive
signal level at that moment and stops transmitting the signal.
