HEADLAMP - XENON TYPE -PFP:26010
Component Parts and Harness Connector LocationAKS007M9
System DescriptionAKS007MA
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) located in the IPDM E/R controls the headlamp high and headlamp low relay coils. These
relays, when energized, direct power to the respective headlamps, which then illuminate.
If voltage is applied to a high beam solenoid, the bulb shade will move, even a xenon head lamp bulb comes
out, and a high beam and a low beam are changed.

through grounds E21, E50 and E51,

to front combination lamp LH terminal 7

through grounds E21, E50 and E51.
With power and ground supplied, the high beam headlamps illuminate.
If voltage is applied to a high beam solenoid, the bulb shade will move, even a xenon head lamp bulb comes
out, and a high beam and a low beam are changed.
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 (IF EQUIPPED)
Refer to LT- 5 5 , "System Description" in “AUTO LIGHT SYSTEM”.
VEHICLE SECURITY SYSTEM
The vehicle security system will flash the high beams if the system is triggered. Refer to BL-186, "VEHICLE
SECURITY (THEFT WARNING) SYSTEM" .
XENON HEADLAMP
Xenon type lamps are used for to the low beam headlamps. Xenon bulbs do not use a filament. Instead, they
produce light when a high voltage current is passed between two tungsten electrodes through a mixture of
xenon (an inert gas) and certain other metal halides. In addition to strong lighting power, electronic control of
the power supply gives the headlamps stable quality and tone color.
Followings are some advantages of the xenon type headlamp.

The light produced by the headlamps is white color similar to sunlight that is easy to the eyes.

Light output is nearly double that of halogen headlamps, affording increased area of illumination.

Retroreflected luminance increases and the contrast enhances on the wet road in the rain. That makes
visibility go up more than the increase of the light volume.

Power consumption is approximately 25 percent less than halogen headlamps, reducing battery load.
CAN Communication System DescriptionAKS007MB
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 UnitAKS0080S

AUTO LIGHT SYSTEM
Revision: 2005 July 2005 FX
When ignition switch is turn to ON position, and
When outside brightness is darker than prescribed level, input is supplied

from BCM terminal 14

to optical sensor terminal 2
The headlamps will then illuminate. For a description of headlamp operation, Refer to LT- 5 5 , "
System Descrip-
tion" .
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 AUTO position, and the ignition switch is turned from
ON or ACC to OFF, and one of the front door is opened, the battery saver control feature is activated.
Under this condition, the headlamp remain illuminated for 5 mimutes, then the headlamp are turned OFF.
Exterior lamp battery saver control mode can be changed by the function setting of CONSULT-II.
DELAY TIMER FUNCTION
Delay timer function carries out a function that BCM activates the timer and controls lights out of headlamps by
door switch signal and lightning switch signal when turning the Ignition switch OFF while it is ON and head-
lamps are ON by the auto light function.
Timer types are a 5-minute timer and a 45-second timer

When opening any door (door switch is ON), the 5-minute timer starts and then headlamps go out five
minutes later

When all the doors are closed (from door switch ON to OFF), the 45-second timer starts and then head-
lamps go out forty-five seconds later. If any door is opened (door switch ON) while the 45-second timer is
in operation, the 5-minute timer starts again

The timer stops when turning on the ignition switch or turning off the auto light switch under the above
conditions.
Delay timer control mode can be changed by the function setting of CONSULT-II or display.

When the key is removed from key switch (key switch OFF), power supply to BCM terminal 37 is terminated.
BCM detects that key has been removed, determines that interior room lamp and map lamp timer conditions
are met, and turns interior room lamp and map lamp ON for 30 seconds.
When driver door opens → closes, and key is not inserted in key switch (key switch OFF), BCM terminal 62
changes between 0V (door open) → 12V (door closed). BCM determines that conditions for interior room lamp
and map lamp operation are met and turns interior room lamp ON for 30 seconds.
Timer control is canceled under the following conditions.

Driver door is locked [when locked keyfob or power window main switch (door lock and unlock switch),
door key cylinder switch].

Driver door is opened (driver door switch turns ON).
