to front combination lamp RH terminal 3,

through 10A fuse [No. 74, located in IPDM E/R]

through IPDM E/R terminal 28

to front combination lamp LH terminal 3.
Ground is supplied

to front combination lamp RH terminals 4, and

to front combination lamp LH terminals 4,

through grounds E17, E43 and B102 (with VDC system, navigation system or telephone)

through grounds E17, E43 and F152 (without VDC system, navigation system and telephone).
With the power and ground supplied, headlamp bulbs illuminate. High beam solenoids move the bulb shades
in the front combination lamps, and the bulb shades change to high beam position.
Unified meter and A/C amp. receives signal from BCM through CAN communication lines, and then combina-
tion meter indicator illuminates high beam.
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-III.
REMOTE KEYLESS ENTRY SYSTEM OPERATION
Refer to BL-59, "REMOTE KEYLESS ENTRY SYSTEM" .
VEHICLE SECURITY SYSTEM
The vehicle security system will flash the high beams if the system is triggered. Refer to BL-125, "VEHICLE
SECURITY (THEFT WARNING) SYSTEM" .
XENON HEADLAMP
Xenon type lamps are used for 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.

Counter-reflected 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 DescriptionNKS004WO
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 UnitNKS004WP
Refer to LAN-48, "CAN System Specification Chart" .

through grounds B5, B6, D105 and T14 (Coupe models)

through grounds B5, B6 and T14 (Roadster models).
With power and ground supplied, the headlamp low, parking, license plate and tail lamps illuminate.
OPERATION

T: “TAIL LAMP” position

Hi: “HIGH BEAM” position

Lo: “LOW BEAM” position

P: “FLASH TO PASS” position

×: Lamp “ON”

–: Lamp “OFF”

*: Once the parking brake is turned OFF after ignition switch ON, parking, license plate, side marker, tail lamps and headlamp low are
turned ON.
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-III.

When driver door opens → closes, and key is not inserted in key switch (key switch OFF), BCM terminal 62
changes between 0V (door open) → 5V (door closed). BCM determines that conditions for spot lamp opera-
tion are met and turns interior lamp ON for 30 seconds.
Timer control is canceled under the following conditions.

Driver door is locked (When locked key fob or power window main switch (door lock and unlock switch,
door key cylinder switch).

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

Ignition switch ON.
INTERIOR LAMP BATTERY SAVER CONTROL
If the room lamp remains illuminated by door switch open signal, or if room lamp switch is in the ON position
for more than 30 minutes after the ignition switch is turned to the OFF position, BCM will automatically turn off
map lamp, luggage room lamp (Coupe models), trunk room lamp (Roadster models) and vanity mirror lamp.
After lamps turn OFF by battery saver system, the lamps illuminate again when

signal from key fob, door lock and unlock switch, or key cylinder is locked or unlocked,

door is opened or closed,

key is removed from ignition key cylinder or inserted in ignition key cylinder.
Interior lamp battery saver control period can be changed by the function setting of CONSULT-III.
