XENON HEADLAMP
A Xenon type headlamp is adapted to the low beam headlamps. Xenon bulbs do not use a filament. Instead,
they produce light when a high voltage current is pa ssed between two tungsten electrodes through a mixture
of xenon (an inert gas) and certain other metal halides. In addition to added lighting power, electronic control
of the power supply gives the headlamps stable quality and tone color.
Following are some of the many advantages of the xenon type headlamp.
• The light produced by the headlamps is a white color comparable to sunlight that is easy on the eyes.
• Light output is nearly double that of halogen headl amps, affording increased area of illumination.
• The light features a high relative spectral distributi on at wavelengths to which the human eye is most sensi-
tive. This means that even in the rain, more light is reflected back from the road surface toward the vehicle,
for added visibility.
• Power consumption is approximately 25 percent less than halogen headlamps, reducing battery load.
LOW BEAM OPERATION
When the lighting switch is in 2nd position, the BCM receives input requesting the headlamps to illuminate.
This input is communicated to the IPDM E/R across the CAN communication lines. The CPU of the IPDM E/R
controls the headlamp low relay coil which supplies power to the low beam headlamps.

SYSTEM
HIGH BEAM OPERATION/FLASH-TO-PASS OPERATION
With the lighting switch in the 2nd position and placed in HIGH position, the BCM receives input requesting the
headlamp high beams to illuminate. The flash to pass f eature can be used any time and also sends a signal to
the BCM. This input is communicated to the IPDM E/R across the CAN communication lines. The CPU of the
combination meter controls the ON/OFF status off the HIGH BEAM indicator. The CPU of the IPDM E/R con-
trols the headlamp high relay coil which supplies power to the high beam headlamps.
The combination meter receives a high beam request signal (ON) through the CAN communication lines and
turns the high beam indicator lamp ON.
EXTERIOR LAMP BATTERY SAVER CONTROL
With the combination switch (lighting and turn signal switch) in the 2nd position and the ignition switch is
turned from ON or ACC to OFF, the battery saver feature is activated.
Under this condition, the headlamps remain illuminated fo r a period of time, unless the lighting switch position
is changed. If the lighting switch position is changed, then the headlamps are turned off.
AUTO LIGHT SYSTEM
AUTO LIGHT SYSTEM : System DiagramINFOID:0000000009463545
AUTO LIGHT SYSTEM : System DescriptionINFOID:0000000009463546
• BCM (Body Control Module) controls auto light operati on according to signals from optical sensor, lighting
switch and ignition switch.
• IPDM E/R (Intelligent Power Distribution Module Engine R oom) operates parking, license plate, tail, front fog
lamps and headlamps according to CAN communication signals from BCM.
• Optical sensor detects ambient brightness of 800 to 2,500 lux. And optical sensor converts light (lux) to volt-
age, then sends the optical sensor signal to BCM.
OUTLINE
The auto light control system has an optical sensor that detects outside brightness.
When the lighting switch is in AUTO position, it autom atically turns ON/OFF the parking, license plate, tail,
front fog lamps and headlamps in accordance with the am bient light. Sensitivity can be adjusted. For the
details of the setting, Refer to BCS-19, "HEADLAMP : CONSULT Function (BCM - HEADLAMP)"

DAYTIME RUNNING LIGHT SY STEM : System DiagramINFOID:0000000009463547
DAYTIME RUNNING LIGHT SYST EM : System DescriptionINFOID:0000000009463548
System Description
The daytime light system is equipped with a daytime light control that activates the daytime lights within the
front fog lamp assembly when the engine is operating. If the parking brake is applied, the daytime lights will
turn OFF. The daytime lights will turn ON when the parking brake is released.
OPERATION
The BCM monitors inputs from the parking brake swit ch and the combination switch (lighting and turn signal
switch) to determine when to operate the daytime light s ystem. The BCM sends a daytime light request to the
IPDM E/R via the CAN communication lines. The IPDM E/ R grounds the daytime light relay which in turn, pro-
vides power to the daytime lights.
FRONT FOG LAMP SYSTEM
FRONT FOG LAMP SYSTEM : System DiagramINFOID:0000000009463549
FRONT FOG LAMP SYSTEM : System DescriptionINFOID:0000000009463550
The front fog lamps are activated with the combination switch (lighting and turn signal switch). The lighting
switch signal to the BCM is monitored with the BCM combination switch reading function. When the fog lamps
are turned ON with the lighting switch, the BCM sends a front fog lamp request signal via CAN communication
lines to the IPDM E/R. The IPDM E/R grounds the front fog lamp relay coil to activate the front fog lamps.
FRONT FOG LAMP OPERATION
When the lighting switch is in front fog lamp ON position and also in 1st or 2nd position or AUTO position
(headlamp is ON), the BCM detects FR FOG ON and the HEAD LAMP 1, 2 ON or the AUTO LIGHT ON. The
BCM sends a front fog lamp request ON signal via the CAN communication lines to the IPDM E/R. The IPDM
E/R then turns ON the front fog lamp re lay sending power to the front fog lamps.

Concept of auto active test
• IPDM E/R starts the auto active test with the door
switch signals transmitted by BCM via CAN communica-
tion. Therefore, the CAN communication line between IPDM E/R and BCM is considered normal if the auto
active test starts successfully.
• The auto active test facilitates troubleshooting if any systems controlled by IPDM E/R cannot be operated.
