PRECAUTIONS
PRECAUTIONS PFP:00011
Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT
BELT PRE-TENSIONER" EKS008LD
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.
General precautions for service operations EKS008LE
q Never work with wet hands.
q The xenon headlamp system includes a high voltage generating
part. Be sure to disconnect battery negative cable (negative ter-
minal) 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.

System Description EKS008LH
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
requesting the headlamps (and tail lamps) to illuminate. This input is communicated to the IPDM E/R (intelli-
gent power distribution module engine room) across the CAN communication lines. The CPU (central pro-
cessing unit) of the IPDM E/R controls the headlamp high and headlamp low relay coils. When energized,
M
these relays direct power to the respective headlamps, which then illuminate.
OUTLINE
Power is supplied at all times
q to headlamp high relay, located in the IPDM E/R, and
q to headlamp low relay, located in the IPDM E/R, and
q through 50A fusible link (letter f , located in the fuse and fusible link box)
q to BCM terminal 70.
With the ignition switch in the ON or START position, power is supplied
q through 10A fuse [No. 1, located in the fuse block (J/B)]
q to BCM terminal 38.
With the ignition switch in the ACC or ON position, power is supplied
q through 10A fuse [No. 6, located in the fuse block (J/B)]
q to BCM terminal 11.
Ground is supplied
Revision: July 2005 LT-5 2006 Altima
HEADLAMP (FOR USA)
q to BCM terminal 67
q through grounds F14, M57 and M61.
Low Beam Operation
With the lighting switch in 2ND position, the BCM receives input requesting the headlamps to illuminate. This
input is communicated to the IPDM E/R across the CAN communication lines. The CPU of the IPDM E/R con-
trols the headlamp low relay coil. When energized, this relay directs power
q through 15A fuse (No. 36, located in the IPDM E/R)
q through IPDM E/R terminal 20
q to headlamp RH terminal 1, and
q through 15A fuse (No. 45, located in the IPDM E/R)
q through IPDM E/R terminal 30
q to headlamp LH terminal 1.
Ground is supplied
q to headlamp RH terminal 2
q to headlamp LH terminal 2
q 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 request-
ing the headlamp high beams to illuminate. This input is communicated to the IPDM E/R across the CAN com-
munication lines. The CPU of the combination meter controls the ON/OFF status of the HIGH BEAM indicator.
The CPU of the IPDM E/R controls the headlamp high relay coil. When energized, this relay directs power
q through 10A fuse (No. 40, located in the IPDM E/R)
q through IPDM E/R terminal 27
q to headlamp RH terminal 1, and
q through 10A fuse (No. 38, located in the IPDM E/R)
q through IPDM E/R terminal 28
q to headlamp LH terminal 1.
Ground is supplied
q to headlamp RH terminal 2
q to headlamp LH terminal 2
q through grounds E15 and E24.
With power and ground supplied, the high beam headlamps illuminate.
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 feature is activated.
Under this condition, the headlamps remain illuminated for 5 minutes, unless the combination switch (lighting
switch) position is changed. If the combination switch (lighting switch) position is changed, then the headlamps
are turned off.
AUTO LIGHT OPERATION
Refer to LT-43, "System Description" for auto light operation.
XENON HEADLAMP (IF EQUIPPED)
The low beam headlamps may be equipped with xenon type bulbs. 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 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.
Revision: July 2005 LT-6 2006 Altima
HEADLAMP (FOR USA)
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.
