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.

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

*: 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.

The BCM then supplies power
through BCM terminal 45
to front combination lamp LH terminal 2
to rear combination lamp LH terminal 2,
through BCM terminal 46
to front combination lamp RH terminal 2
to rear combination lamp RH terminal 2.
Ground is supplied
to front combination lamp LH terminal 8, and
to front combination lamp RH terminal 8
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),
to rear combination lamp LH terminal 4, and
to rear combination lamp RH terminal 4
through grounds B5, B6, D105 and T14 (Coupe models)
through grounds B5, B6 and T14 (Roadster models).
The BCM also supplies input to unified meter and A/C amp. terminals 1 and 11 through the CAN communica-
tion lines. This input signal is processed by the unified meter control unit in the combination meter through the
unified meter and A/C amp., which in turn supplies ground to the left and right turn signal indicator lamps.
With the power and ground supplied, BCM controls the flashing of hazard warning lamps.

System DescriptionNKS004ZK
When the map lamp switch is in the DOOR position, map lamp ON/OFF is controlled by timer according to sig-
nals from switches including key switch, door switch driver side and assist side, unlock and lock signal from
key fob, door lock and unlock switch, key cylinder lock and unlock switch, ignition switch.
When the map lamp turns ON, there is a gradual brightening over 1 second. When map lamp turns OFF, there
is a gradual dimming over 1 second.
Map lamp timer is controlled by BCM (body control module).
Map lamp timer control settings can be changed with CONSULT-III.
Ignition key hole illumination turns ON at time when driver door is opened (door switch ON) or removed key
fob from key cylinder. Illumination turns OFF when driver door is closed (door switch OFF).
