●
Installation or removal of the connector must be done with the lighting switch OFF.
●
When the lamp is illuminated (when the lighting switch is ON), do not touch the harness, HID control unit,
inside of the lamp, or the lamp metal parts.
●
To check illumination, temporarily install lamp in the vehicle. Be sure to connect power at the vehicle-side
connector.
●
If the error can be traced directly to the electrical system, first check for items such as burned-out fuses
and fusible links, broken wires or loose connectors, pulled-out terminals, and improper connections.
●
Do not work with wet hands.
●
Using a tester for HID control unit circuit trouble diagnosis is prohibited.
●
Disassembling the HID control unit or harnesses (bulb socket harness, ECM harness) is prohibited.
●
Immediately after illumination, the light intensity and color will fluctuate, but there is nothing wrong.
●
When the bulb has reached the end of its lifetime, the brightness may drop significantly, it may flash
repeatedly, or the light may turn a reddish color.

Component Parts and Harness Connector Location

System Description
AKS007LM
Control of the headlamp system operation is dependent upon the position of the combination switch (lighting
switch). When the lighting switch is placed in the 2ND position, the BCM (body control module) receives input
signal requesting the headlamps (and tail lamps) illuminate. This input signal is communicated to the IPDM E/
R (intelligent power distribution module engine room) across the CAN communication lines. The CPU (central
processing unit) of the IPDM E/R (intelligent power distribution module engine room) controls the headlamp
high and headlamp low relay coils. These relays, when energized, direct power to the respective headlamps,
which then illuminate.

HEADLAMP OPERATION
Low Beam Operation
With the lighting switch in 2ND position, the BCM receives input signal requesting the headlamps to illuminate.
This input signal is communicated to the IPDM E/R across the CAN communication lines. The CPU in the
IPDM E/R controls the headlamp low relay coil, which when energized, directs power
●
to 15A fuse [No. 76, located in IPDM E/R]
●
through IPDM E/R terminal 20
●
to headlamp RH terminal 4
●
to 15A fuse [No. 86, located in IPDM E/R]
●
through IPDM E/R terminal 30
●
to headlamp LH terminal 4.
Ground is supplied at all times
●
to headlamp RH terminal 5
●
through grounds E13, E26 and E28
●
to headlamp LH terminal 5
●
through grounds E13, E26 and E28.
With power and ground supplied, low beam headlamps illuminate.
High Beam Operation/Flash-to-Pass Operation
With the lighting switch in 2ND position and placed in HIGH or PASS position, the BCM receives input signal
requesting the headlamp high beams to illuminate. This input signal is communicated to the IPDM E/R across
the CAN communication lines. The CPU in the IPDM E/R controls the headlamp high relay coil, which when
energized, directs power
●
to 10A fuse [No. 72, located in IPDM E/R]
●
through IPDM E/R terminal 27
●
to headlamp RH terminal 1
●
to 10A fuse [No. 74, located in IPDM E/R]
●
through IPDM E/R terminal 28
●
to headlamp LH terminal 1.
Ground is supplied

With power and ground supplied, the high beam headlamps illuminate.
The unified meter and A/C amp that received the high beam request signal by BCM across the CAN commu-
nication makes a high beam indicator lamp turn on in combination meter.
COMBINATION SWITCH READING FUNCTION
Refer to
BCS-3, "COMBINATION SWITCH READING FUNCTION"
.
EXTERIOR LAMP BATTERY SAVER CONTROL
When the combination switch (lighting switch) is in the 2ND position (ON), and the ignition switch is turned
from ON or ACC to OFF, the battery saver control function is activated.
Under this condition, the headlamps remain illuminated for 5 minutes, then the headlamps are turned off.
Exterior lamp battery saver control mode can be changed by the function setting of CONSULT-II.
AUTO LIGHT OPERATION
Refer to
in “AUTO LIGHT SYSTEM”.
VEHICLE SECURITY SYSTEM
The vehicle security system will flash the high beams if the system is triggered. Refer to
SECURITY (THEFT WARNING) SYSTEM"
.
CAN Communication System Description
AKS007LN
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.
