HEADLAMP - XENON TYPE -
Revision: 2005 July 2005 FX
With ignition switch in ON or START position, power is supplied

to ignition relay, located in IPDM E/R, from battery direct

through 15A fuse [No. 1, located in fuse block (J/B)]

to BCM terminal 38,

through 10A fuse [No. 14, located in fuse block (J/B)]

to combination meter terminal 7.
With ignition switch in ACC or ON position, power is supplied

through 10A fuse [No. 6, located in fuse block (J/B)]

to BCM terminal 11.
Ground is supplied

to BCM terminals 49 and 52

through grounds M35, M45 and M85,

to IPDM E/R terminals 38 and 60

through grounds E21, E50 and E51,

to combination meter terminals 5, 6 and 15

through grounds M35, M45 and M85.
HEADLAMP OPERATION
Low Beam Operation
With the lighting switch in the 2ND position, the BCM receives input signal requesting the headlamps to illumi-
nate. This input signal is communicated to the IPDM E/R across the CAN communication lines. The CPU
located in the IPDM E/R controls the headlamp low relay coil, which when energized, directs power

through 15A fuse (No. 76, located in IPDM E/R)

through IPDM E/R terminal 20

to front combination lamp RH terminal 6,

through 15A fuse (No. 86, located in IPDM E/R)

through IPDM E/R terminal 30

to front combination lamp LH terminal 6.
Ground is supplied

to front combination lamp RH terminal 7

through grounds E21, E50 and E51,

to front combination lamp LH terminal 7

through grounds E21, E50 and E51.
With power and ground supplied, low beam headlamps illuminate.
High Beam Operation/Flash-to-Pass Operation
With the lighting switch in the 2ND position and placed in the 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 located in the IPDM E/R controls the headlamp high relay coil
and low relay coil, which when energized, directs power

through 15A fuse (No. 76, located in IPDM E/R)

through IPDM E/R terminal 20

to front combination lamp RH terminal 6,

through 15A fuse (No. 86, located in IPDM E/R)

through IPDM E/R terminal 30

to front combination lamp LH terminal 6,

through 10A fuse (No. 72, located in IPDM E/R)

through IPDM E/R terminal 27

to front combination lamp RH terminal 5,

through 10A fuse (No. 74, located in IPDM E/R)

through IPDM E/R terminal 28

to front combination lamp LH terminal 5.
Ground is supplied

to front combination lamp RH terminal 7

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
Refer to LAN-30, "CAN Communication Unit" .
