HEADLAMP AUTO 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 lighting switch is turned to the 1ST or 2ND position, power is supplied

through IPDM E/R terminal 22

to height sensor terminal 6 and

to front combination lamp RH and LH terminals 3.
At the same time, the vehicle height signal (voltage signal that corresponds to the vehicle height) is applied

through height sensor terminal 7

to front combination lamp RH and LH terminals 6.
Ground is supplied

to front combination lamp RH and LH terminals 4

through grounds E1 and E31.
CAN Communication System DescriptionBKS0041M
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
CAN Communication UnitBKS0041N
Refer to LAN-49, "CAN System Specification Chart" .

How to Proceed With Trouble DiagnosisBKS002BG
1. Confirm the symptom or customer complaint.
2. Understand operation description and function description. Refer to LT- 9 6 , "
System Description" .
3. Perform self-diagnosis by CONSULT-II. Refer to LT- 1 0 5 , "
SELF-DIAG RESULTS" .
4. Check symptom and repair or replace the cause of malfunction.
5. Does the headlamp aiming control operate normally? If YES, GO TO 6. If NO, GO TO 4.
6. INSPECTION END
