Removal and InstallationEKS003CA
1. Remove the Instrument lower driver panel. Refer to IP-11,
"Removal and Installation" in “INSTRUMENT PANEL ASSEM-
BLY (IP)” section.
2. Press the headlamp aiming switch fixing pawls and remove it
from the Instrument lower driver panel.
Switch Circuit InspectionEKS003CB
Using a circuit tester, check continuity between the headlamp aiming
switch connector terminals in each operation status of the aiming
switch.

HEADLAMP AIMING CONTROL (AUTO)PFP:53821
Component Parts and Harness Connector LocationEKS00N5W
System DescriptionEKS00N5X
With the lighting switch in the 1ST or 2ND position, the height sensor detects change in the vehicle height and
transmits a corresponding signal to the headlamp aiming motors. The signal drives the headlamp 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.
OUTLINE
Power is supplied at all times

through 10A fuse (No. 31, located in fuse and fusible link box)

to lighting switch terminal 11, and

to daytime light control unit terminal 1 (with daytime light system).
With the ignition switch in the ON or START 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.
Ground is supplied

to height sensor terminal 5

through grounds B107 and B119,

to headlamp aiming motor RH and LH terminal 3

HEADLAMP AIMING CONTROL (AUTO)


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.
