PRECAUTIONS
PRECAUTIONS PFP:00011
A
Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT
BELT PRE-TENSIONER" AKS003NJ
The Supplemental Restraint System such as "AIR BAG" and "SEAT BELT PRE-TENSIONER", used along B
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 C
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: D
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. E
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. F
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 harness connec-
tors.
G
Precautions for Battery Service AKS003RF
This vehicle is equipped with the automatic window adjusting function. When a door is opened, the window
automatically lowers slightly to avoid contact between the window and the side roof panel. After the door is H
closed, the window will automatically raise slightly.
On vehicles equipped with the automatic window adjusting function, lower both the driver and front passenger I
side windows before disconnecting the battery cables. This will prevent interference between the side window
and the roof panel when either door is opened/closed.
J
CAUTION:
After the battery cables are disconnected, do not open/close the driver and/or front passenger door
with the window in the full up position. The automatic window adjusting function will not work and the
side roof panel may be damaged. LT

PRECAUTIONS
General precautions for service operations AKS000SE
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- PKIA0183E
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.
Wiring Diagrams and Trouble Diagnosis AKS000SF
When you read wiring diagrams, refer to the following:
q Refer to GI-15, "How to Read Wiring Diagrams" in GI section.
q Refer to PG-4, "POWER SUPPLY ROUTING CIRCUIT" for power distribution in PG section.
When you perform trouble diagnosis, refer to the following:
q Refer to GI-11, "HOW TO FOLLOW TEST GROUPS IN TROUBLE DIAGNOSES" in GI section.
q Refer to GI-27, "How to Perform Efficient Diagnosis for an Electrical Incident" in GI section.

System Description AKS002SM
Control of the headlamp system operation is dependent upon the position of the combination switch (lighting H
switch). When the lighting switch is placed in the 2ND position, the BCM receives input 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 central processing unit of the
I
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.
OUTLINE J
Power is supplied at all times
q to headlamp high relay, located in the IPDM E/R (intelligent power distribution module engine room), and
q to headlamp low relay, located in the IPDM E/R (intelligent power distribution module engine room), and LT
q to BCM (body control module) terminal 7
q through 40A fusible link (letter F, located in the fuse and fusible link box).
q through 15A fuse [No.73 located in IPDM E/R (intelligent power distribution module engine room)] L
q to CPU (central processing unit) in the IPDM E/R (intelligent power distribution module engine room).
With the ignition switch in the ON or START position, power is supplied
M
q to BCM (body control module) terminal 35
q through 10A fuse [No. 1, located in the fuse block (J/B)].
q to CPU (central processing unit) in the IPDM E/R (intelligent power distribution module engine room).
q through 10A fuse [No.80,located in IPDM E/R (intelligent power distribution module engine room)].
With the ignition switch in the ACC or ON position, power is supplied
q to BCM (body control module) terminal 36
q through 10A fuse [No. 6, located in the fuse block (J/B)].
Ground is supplied
q to BCM (body control module) terminal 8
q through grounds E17, E43 and F152.
Low Beam Operation
With the lighting switch in 2ND position, the BCM (body control module) receives input signal requesting by
combination switch reading function (Refer to LT-159, "Combination Switch Reading Function" ) the head-
lamps to illuminate. This input signal is communicated to the IPDM E/R (intelligent power distribution module
LT-7
HEADLAMP (FOR USA) - XENON TYPE -
engine room) across the CAN communication lines. The CPU (central processing unit) in the IPDM E/R con-
trols the headlamp low relay coil, which when energized, power is supplied.
q through 15A fuse [No. 83, located in the IPDM E/R (intelligent power distribution module engine room)]
q through terminal 27 of the IPDM E/R
q to terminal 7 of headlamp RH, and
q through 15A fuse [No. 84, located in the IPDM E/R (intelligent power distribution module engine room)]
q through terminal 21 of the IPDM E/R
q to terminal 7 of headlamp LH.
Ground is supplied
q to terminal 8 of each headlamp
q through grounds E17,E43 and F152, and
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 (body control module)
receives input signal requesting the headlamp high beams to 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) in the IPDM E/R controls the headlamp high relay coil, which when energized,
directs power
q to 10A fuse [No. 86, located in the IPDM E/R]
q through terminal 24 of the IPDM E/R
q to terminal 3 of headlamp RH, and
q to 10A fuse [No. 85, located in the IPDM E/R]
q through terminal 22 of the IPDM E/R
q to terminal 3 of headlamp LH.
Ground is supplied
q to terminal 4 of headlamp RH
q through grounds E17,E43 and F152, and
q to terminal 4 of headlamp LH
q through grounds E17,E43 and F152,
With power and ground supplied, the high beam headlamps illuminate.
Unified meter and A/C amp receives signal from the BCM across the CAN communication lines, and then
combination meter indicator illuminates high beam.
COMBINATION SWITCH READING FUNCTION
Refer to LT-159, "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.
VEHICLE SECURITY SYSTEM
The vehicle security system will flash the high beams if the system is triggered. Refer to BL-90, "VEHICLE
SECURITY (THEFT WARNING) SYSTEM" .
XENON HEADLAMP (IF EQUIPPED)
Xenon type headlamp is adopted to the low 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.
Following are some of the many advantages of the xenon type headlamp.
q The light produced by the headlamps is a white color comparable to sunlight that is easy on the eyes.
q Light output is nearly double that of halogen headlamps, affording increased area of illumination.
LT-8
HEADLAMP (FOR USA) - XENON TYPE -
q 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- A
cle, for added visibility.
q Power consumption is approximately 25 percent less than halogen headlamps, reducing battery load.
CAN Communication System Description AKS003MX
B
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-
C
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
