PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000009951582
The Supplemental Restraint System such as “A IR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severi ty of injury to the driver and front passenger for certain
types of collision. Information necessary to service the system safely is included in the SR and SB section of
this Service Manual.
WARNING:
• To avoid rendering the SRS inopera tive, 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 performed by
an authorized NISS AN/INFINITI dealer.
• Improper maintenance, including in correct removal and installation of the SRS, can lead to personal
injury caused by unintent ional activation of the system. For re moval of Spiral Cable and Air Bag
Module, see the SR section.
• Do not use electrical test equipmen t on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harn esses can be identified by yellow and/or orange harnesses or har-
ness connectors.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
• When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or electri c power tools or strike near the sensor(s) with a
hammer. Heavy vibration could activate the sensor( s) and deploy the air bag(s), possibly causing
serious injury.
• When using air or electric power tools or hammers , always switch the Ignition OFF, disconnect the
battery and wait at least three minutes before performing any service.
General precautions fo r service operationsINFOID:0000000009463538
• Do not work with wet hands.
• The xenon headlamp system includes a high voltage generating
part. Be sure to disconnect batte ry negative cable (negative termi-
nal) or power fuse before removing, installing, or touching the
xenon headlamp (including lamp bulb).
• Turn the lighting switch OFF before disconnecting and connecting the connector.
• When turning the xenon headlamp on and while it is illuminated, do
not touch the harness, bulb, and socket of the headlamp.
• When checking the headlamp on/off operation, check it on vehicle and with the power connected to the vehicle-side connector.
• Do not touch the headlamp bulb glass surface with bare hands or allow oil or grease to get on it. Do not touch the headl amp bulb just after the headlamp is turned off, because
it is very hot.
• Install the xenon headlamp bulb socket co rrectly. If it is installed improperly, high-voltage leak or corona dis-
charge may occur that can melt the bulb, connector or housing. Do not illuminate the xenon headlamp bulb
out of the headlamp housing. Doing so can cause fire and harm your eyes.
• When the bulb has burned out, wrap it in a thick vinyl bag and discard. Do not break the bulb.
• Leaving the bulb removed from the headlamp housing for a long period of time can deteriorate the perfor- mance of the lens and reflector (dirt, clouding). Al ways prepare a new bulb and have it on hand when replac-
ing the bulb.
• When adjusting the headlamp aiming, turn the aiming adjus tment 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.
• Do not use organic solvent (paint thinner or gasoline) to clean lamps and to remove old sealant.

HEADLAMP SYSTEM : System DescriptionINFOID:0000000009463544
XENON HEADLAMP
A Xenon type headlamp is adapted to the low beam headlamps. Xenon bulbs do not use a filament. Instead,
they produce light when a high voltage current is pa ssed 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.
• The light produced by the headlamps is a white color comparable to sunlight that is easy on the eyes.
• Light output is nearly double that of halogen headl amps, affording increased area of illumination.
• The light features a high relative spectral distributi on at wavelengths to which the human eye is most sensi-
tive. This means that even in the rain, more light is reflected back from the road surface toward the vehicle,
for added visibility.
• Power consumption is approximately 25 percent less than halogen headlamps, reducing battery load.
LOW BEAM OPERATION
When the lighting switch is 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
controls the headlamp low relay coil which supplies power to the low beam headlamps.

SYSTEM
HIGH BEAM OPERATION/FLASH-TO-PASS OPERATION
With the lighting switch in the 2nd position and placed in HIGH position, the BCM receives input requesting the
headlamp high beams to illuminate. The flash to pass f eature can be used any time and also sends a signal to
the BCM. This input is communicated to the IPDM E/R across the CAN communication lines. The CPU of the
combination meter controls the ON/OFF status off the HIGH BEAM indicator. The CPU of the IPDM E/R con-
trols the headlamp high relay coil which supplies power to the high beam headlamps.
The combination meter receives a high beam request signal (ON) through the CAN communication lines and
turns the high beam indicator lamp ON.
EXTERIOR LAMP BATTERY SAVER CONTROL
With the combination switch (lighting and turn signal switch) in the 2nd position and the ignition switch is
turned from ON or ACC to OFF, the battery saver feature is activated.
Under this condition, the headlamps remain illuminated fo r a period of time, unless the lighting switch position
is changed. If the lighting switch position is changed, then the headlamps are turned off.
AUTO LIGHT SYSTEM
AUTO LIGHT SYSTEM : System DiagramINFOID:0000000009463545
AUTO LIGHT SYSTEM : System DescriptionINFOID:0000000009463546
• BCM (Body Control Module) controls auto light operati on according to signals from optical sensor, lighting
switch and ignition switch.
• IPDM E/R (Intelligent Power Distribution Module Engine R oom) operates parking, license plate, tail, front fog
lamps and headlamps according to CAN communication signals from BCM.
• Optical sensor detects ambient brightness of 800 to 2,500 lux. And optical sensor converts light (lux) to volt-
age, then sends the optical sensor signal to BCM.
OUTLINE
The auto light control system has an optical sensor that detects outside brightness.
When the lighting switch is in AUTO position, it autom atically turns ON/OFF the parking, license plate, tail,
front fog lamps and headlamps in accordance with the am bient light. Sensitivity can be adjusted. For the
details of the setting, Refer to BCS-19, "HEADLAMP : CONSULT Function (BCM - HEADLAMP)"

DAYTIME RUNNING LIGHT SY STEM : System DiagramINFOID:0000000009463547
DAYTIME RUNNING LIGHT SYST EM : System DescriptionINFOID:0000000009463548
System Description
The daytime light system is equipped with a daytime light control that activates the daytime lights within the
front fog lamp assembly when the engine is operating. If the parking brake is applied, the daytime lights will
turn OFF. The daytime lights will turn ON when the parking brake is released.
OPERATION
The BCM monitors inputs from the parking brake swit ch and the combination switch (lighting and turn signal
switch) to determine when to operate the daytime light s ystem. The BCM sends a daytime light request to the
IPDM E/R via the CAN communication lines. The IPDM E/ R grounds the daytime light relay which in turn, pro-
vides power to the daytime lights.
FRONT FOG LAMP SYSTEM
FRONT FOG LAMP SYSTEM : System DiagramINFOID:0000000009463549
FRONT FOG LAMP SYSTEM : System DescriptionINFOID:0000000009463550
The front fog lamps are activated with the combination switch (lighting and turn signal switch). The lighting
switch signal to the BCM is monitored with the BCM combination switch reading function. When the fog lamps
are turned ON with the lighting switch, the BCM sends a front fog lamp request signal via CAN communication
lines to the IPDM E/R. The IPDM E/R grounds the front fog lamp relay coil to activate the front fog lamps.
FRONT FOG LAMP OPERATION
When the lighting switch is in front fog lamp ON position and also in 1st or 2nd position or AUTO position
(headlamp is ON), the BCM detects FR FOG ON and the HEAD LAMP 1, 2 ON or the AUTO LIGHT ON. The
BCM sends a front fog lamp request ON signal via the CAN communication lines to the IPDM E/R. The IPDM
E/R then turns ON the front fog lamp re lay sending power to the front fog lamps.
