through grounds E24 and E50.
HEADLAMP AIMING CONTROL OPERATION
The height 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
through 10A fuse [No. 5 located in fuse block (J/B)]
to height sensor terminal 1, and
to headlamp aiming motor RH and LH terminal 1.
At the same time, the vehicle height signal (voltage signal that corresponds to the vehicle height) is applied
through height sensor terminal 3
to headlamp aiming motor RH and LH terminal 2.
Ground is supplied
to headlamp aiming motor RH and LH terminal 3
through grounds E24 and E50,
to height sensor terminal 5
through grounds B107 and B119.
And the voltage level of this signal is maintained.
When the lighting switch is placed in the 1ST or 2ND position, power is supplied (without daytime light system)
through lighting switch terminal 12
to height sensor terminal 8.
When the lighting switch is placed in the 1ST or 2ND position, power is supplied (with daytime light system)
through lighting switch terminal 12
to daytime light control unit terminal 11
through daytime light control unit terminal 10
to height sensor terminal 8.
Ground is supplied
to height sensor terminal 5
through grounds B107 and B119.
The height sensor starts the aiming control.
When the stopped vehicle changes the height and keeps it for more than 10 seconds, the height sensor out-
puts a headlamp aiming motor drive signal. And height sensor keeps signal 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 height sensor transmits headlamp
aiming motor drive signal to headlamp aiming motors at the predetermined intervals. The voltage 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 height sensor keeps the same headlamp aiming 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 height sensor retains the headlamp aiming motor drive signal level
at that moment and stops transmitting the signal.
