PRECAUTIONS

PRECAUTIONS PFP:00011

Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT
BELT PRE-TENSIONER" NKS002KQ

The Supplemental Restraint System such as "AIR BAG" and "SEAT BELT PRE-TENSIONER", used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Man-
ual.
WARNING:
q To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be per-
formed by an authorized NISSAN/INFINITI dealer.
q Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
q Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.
Precautions for Battery Service NKS002KT

Before disconnecting the battery, lower both the driver and passenger windows. This will prevent any interfer-
ence between the window edge and the vehicle when the door is opened/closed. During normal operation, the
window slightly raises and lowers automatically to prevent any window to vehicle interference. The automatic
window function will not work with the battery disconnected.
General Precautions for Service Operations NKS002KR

q Never work with wet hands.
q Xenon headlamp includes high voltage generating part. Be sure
to disconnect battery negative cable (negative terminal) or
power fuse before removing, installing, or touching the xenon
headlamp (including lamp bulb).
q Turn the lighting switch OFF before disconnecting and connect-
ing the connector.
q When turning the xenon headlamp on and while it is illuminated,
never touch the harness, bulb, and socket of the headlamp.
q When checking the headlamp on/off operation, check it on vehi- PKIB7344E
cle and with the power connected to the vehicle-side connector.
q Do not touch the headlamp bulb glass surface with bare hands or allow oil or grease to get on it. Do not
touch the headlamp bulb just after the headlamp is turned off, because it is very hot.
q Install the xenon headlamp bulb socket correctly. If it is installed
improperly, high-voltage leak or corona discharge may occur
that can melt the bulb, connector, and housing. Do not illuminate
the xenon headlamp bulb out of the headlamp housing. Doing
so can cause fire and harm your eyes.
q When the bulb has burned out, wrap it in a thick vinyl bag and
discard. Do not break the bulb.
q Leaving the bulb removed from the headlamp housing for a long
period of time can deteriorate the performance of the lens and
reflector (dirt, clouding). Always prepare a new bulb and have it
on hand when replacing the bulb. EL-3422D

q When adjusting the headlamp aiming, turn the aiming adjust-
ment screw only in the tightening direction. (If it is necessary to loosen the screw, first fully loosen the
screw, and then turn it in the tightening direction.)
q Do not use organic solvent (paint thinner or gasoline) to clean lamps and to remove old sealant.

System Description NKS0000Q

Control of the headlamp system operation is dependent upon the position of the combination switch (lighting
switch). When the lighting switch is placed in the 2ND position, the BCM (body control module) receives input L
signal requesting the headlamps (and tail lamps) illuminate. This input signal is communicated to the IPDM E/
R (intelligent power distribution module engine room) through the CAN communication lines. The CPU (central
processing unit) of the IPDM E/R controls the headlamp high and headlamp low relay coils. These relays,
M
when energized, direct power to the respective headlamps, which then illuminate.
OUTLINE
Power is supplied at all times
q to headlamp high relay, located in IPDM E/R and
q to headlamp low relay, located in IPDM E/R, from battery directly,

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,
q through 15A fuse [No. 76, located in IPDM E/R]
q through IPDM E/R terminal 20
q to front combination lamp RH terminal 7,
q through 15A fuse [No. 86, located in IPDM E/R]
q through IPDM E/R terminal 30
q to front combination lamp LH terminal 7.
Ground is supplied
q to front combination lamp RH terminal 4, and
q to front combination lamp LH terminal 4
q through grounds E17, E43 and F152.
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,
q through 15A fuse [No. 76, located in IPDM E/R]
q through IPDM E/R terminal 20
q to front combination lamp RH terminal 7,
q through 15A fuse [No. 86, located in IPDM E/R]
q through IPDM E/R terminal 30
q to front combination lamp LH terminal 7,
q through 10A fuse [No. 72, located in IPDM E/R]
q through IPDM E/R terminal 27
q to front combination lamp RH terminal 3,
q through 10A fuse [No. 74, located in IPDM E/R]

q through IPDM E/R terminal 28
q to front combination lamp LH terminal 3. A
Ground is supplied
q to front combination lamp RH terminals 4, and
B
q to front combination lamp LH terminals 4,
q through grounds E17,E43 and F152.
With the power and ground supplied, headlamp bulbs illuminate. High beam solenoids move the bulb shades C
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.
D
COMBINATION SWITCH READING FUNCTION
Refer to BCS-3, "COMBINATION SWITCH READING FUNCTION" .
EXTERIOR LAMP BATTERY SAVER CONTROL E
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. F
Exterior lamp battery saver control mode can be changed by the function setting of CONSULT-II.
REMOTE KEYLESS ENTRY SYSTEM OPERATION
Refer to BL-62, "REMOTE KEYLESS ENTRY SYSTEM" . G

VEHICLE SECURITY SYSTEM
The vehicle security system will flash the high beams if the system is triggered. Refer to BL-135, "VEHICLE H
SECURITY (THEFT WARNING) SYSTEM" .
XENON HEADLAMP
Xenon type lamps are used for headlamps. Xenon bulbs do not use a filament. Instead, they produce light I
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. J
Followings are some advantages of the xenon type headlamp.
q The light produced by the headlamps is white color similar to sunlight that is easy to the eyes.
q Light output is nearly double that of halogen headlamps, affording increased area of illumination. LT
q 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.
q Power consumption is approximately 25 percent less than halogen headlamps, reducing battery load. L
CAN Communication System Description NKS0000R

CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
M
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 Unit NKS0000S

Refer to LAN-24, "CAN Communication Unit" .
