PRECAUTIONS

PRECAUTIONS PFP:00011

Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT
BELT PRE-TENSIONER" EKS008YG

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:
G 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.
G 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.
G 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.
General precautions for service operations EKS008YH

G Never work with wet hands.
G 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).
G Turn the lighting switch OFF before disconnecting and connect-
ing the connector.
G When turning the xenon headlamp on and while it is illuminated,
never touch the harness, bulb, and socket of the headlamp.
G When checking the headlamp on/off operation, check it on vehi- WKIA0460E
cle and with the power connected to the vehicle-side connector.
G 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.
G 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.
G When the bulb has burned out, wrap it in a thick vinyl bag and
discard. Do not break the bulb.
G 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

G Do not use organic solvent (paint thinner or gasoline) to clean
lamps and to remove old sealant.

System Description EKS008YK
F

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
G
signal requesting the headlamps (and tail lamps) illuminate. This input signal is communicated to the IPDM E/
R (intelligent power distribution module engine room) across 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,
when energized, direct power to the respective headlamps, which then illuminate. H
If voltage is applied to a high beam solenoid, the bulb shade will move and a high beam and a low beam are
changed.

G to IPDM E/R terminals 38 and 60
G through grounds E15 and E24.
Low Beam Operation
With the lighting switch in 2ND position, the BCM receives input signal requesting the headlamps to illuminate.
This input signal is communicated to the IPDM E/R across the CAN communication lines. The CPU of the
IPDM E/R controls the headlamp low relay coil, which when energized, directs power
G through 15A fuse (No. 36, located in the IPDM E/R)
G to IPDM E/R terminal 20
G to front combination lamp RH (headlamp) terminal 3, and
G through 15A fuse (No. 45, located in the IPDM E/R)
G to IPDM E/R terminal 30
G to front combination lamp LH (headlamp) terminal 3.
Ground is supplied
G to front combination lamp LH and RH (headlamp) terminal 4
G through grounds E15 and E24.
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 the headlamp high beams to illuminate. This input signal is communicated to the IPDM E/R across
the CAN communication lines. The CPU of the IPDM E/R controls the headlamp high relay coil and low relay
coil, which when energized, directs power
G through 15A fuse (No. 36, located in the IPDM E/R)
G to IPDM E/R terminal 20
G to front combination lamp RH (headlamp) terminal 3, and
G through 15A fuse (No. 45, located in the IPDM E/R)
G to IPDM E/R terminal 30
G to front combination lamp LH (headlamp) terminal 3, and
G through 10A fuse (No. 40, located in the IPDM E/R)
G to IPDM E/R terminal 27
G to front combination lamp RH (headlamp) terminal 7, and
G through 10A fuse (No. 38, located in the IPDM E/R)
G to IPDM E/R terminal 28
G to front combination lamp LH (headlamp) terminal 7.
Ground is supplied
G to front combination lamp LH and RH (headlamp) terminals 4 and 8
G through grounds E15 and E24.
With power and ground supplied, the high beam headlamps illuminate.
If voltage is applied to a high beam solenoid, the bulb shade will move 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 across the CAN commu-
nication makes the 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
Refer to LT-50, "System Description" in AUTO LIGHT SYSTEM.

VEHICLE SECURITY SYSTEM
The vehicle security system will flash the high beams if the system is triggered. Refer to BL-131, "VEHICLE A
SECURITY (THEFT WARNING) SYSTEM" .
XENON HEADLAMP (IF EQUIPPED)
B
Xenon type headlamp is adopted to the low and high 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 added lighting power, electronic
control of the power supply gives the headlamps stable quality and tone color. C
Following are some of the many advantages of the xenon type headlamp.
G The light produced by the headlamps is a white color comparable to sunlight that is easy on the eyes.
G Light output is nearly double that of halogen headlamps, affording increased area of illumination. D
G The light features a high relative spectral distribution at wavelengths to which the human eye is most sen-
sitive. This means that even in the rain, more light is reflected back from the road surface toward the vehi-
cle for added visibility. E
G Power consumption is approximately 25 percent less than halogen headlamps, reducing battery load.
