to combination meter terminal 24.
With ignition switch in ON or START position, power is supplied
to CPU located in IPDM E/R,
through 10A 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 23.
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 terminal 52
through grounds M30 and M66,
to IPDM E/R terminals 38 and 60
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 combination meter terminals 10, 11 and 12
through grounds M30 and M66.
HEADLAMP OPERATION
Low Beam Operation
With the lighting switch in 2ND position, the BCM receives input signal from combination switch reading func-
tion (Refer to BCS-3, "
COMBINATION SWITCH READING FUNCTION" ) the headlamp to illuminate. This
input signal is communicated to the IPDM E/R through the CAN communication lines. The CPU located in the
IPDM E/R controls the headlamp low relay coil, which when energized, supplies power,
through 15A fuse [No. 76, located in IPDM E/R]
through IPDM E/R terminal 20
to front combination lamp RH terminal 7,
through 15A fuse [No. 86, located in IPDM E/R]
through IPDM E/R terminal 30
to front combination lamp LH terminal 7.
Ground is supplied
to front combination lamp RH terminal 4, and
to front combination lamp LH terminal 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 power and ground supplied, low beam headlamps illuminate.
High Beam Operation/Flash-to-Pass Operation
With the lighting switch in 2ND position and placed in HIGH or PASS position, the BCM receives input signal
requesting headlamp high beams to illuminate. High beam request signal and low beam request signal is com-
municated to the IPDM E/R through CAN communication. The CPU located in the IPDM E/R controls head-
lamp high relay and headlamp low relay turned ON, which when energized, supplies power,
through 15A fuse [No. 76, located in IPDM E/R]
through IPDM E/R terminal 20
to front combination lamp RH terminal 7,
through 15A fuse [No. 86, located in IPDM E/R]
through IPDM E/R terminal 30
to front combination lamp LH terminal 7,
through 10A fuse [No. 72, located in IPDM E/R]
through IPDM E/R terminal 27

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" .
