Revision: 2006 December 2006 FX35/FX45
Ground is supplied

to front combination lamp RH and LH terminals 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 through 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 6 , "System Description" .
VEHICLE SECURITY SYSTEM
The vehicle security system will flash the high beams if the system is triggered. Refer to BL-180, "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 DescriptionNKS002V7
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.

through grounds M35, M45 and M85,

to IPDM E/R terminals 38 and 60

through grounds E21, E50 and E51.
FRONT FOG LAMP OPERATION
The front fog lamp switch is built into combination switch. The lighting switch must be in the 2ND position or
AUTO position (headlamp is ON) and the front fog lamp switch must be ON for front fog lamp operation.
With the front fog lamp switch in the ON position, the CPU located in the IPDM E/R grounds the coil side of the
front fog lamp relay. The front fog lamp relay then directs power

through IPDM E/R terminal 36

to front fog lamp RH terminal 1,

through IPDM E/R terminal 37

to front fog lamp LH terminal 1.
Ground is supplied

to front fog lamp RH and LH terminals 2

through grounds E21, E50 and E51.
With power and grounds supplied, front fog lamps illuminate.
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), the front fog lamp switch is ON, and
the ignition switch is turned from ON or ACC to OFF, the battery saver control feature is activated.
Under this condition, the front fog lamps (and headlamps) remain illuminated for 5 minutes, then the front fog
lamps (and headlamps) are turned off.
Exterior lamp battery saver control mode can be changed by the function setting of CONSULT-II.
CAN Communication System DescriptionNKS002WY
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.
