Precaution for Supplemental Restraint Syst
em (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000009951635
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.
Precautions For Harness RepairINFOID:0000000009464647
ITS communication uses a twisted pair line. Be careful when repairing it.
• Solder the repaired area and wrap tape around the soldered area.
NOTE:
A fray of twisted lines must be within 110 mm (4.33 in).
• Bypass connection is never allowed at the repaired area. NOTE:
Bypass connection may cause ITS communication error. The
spliced wire becomes separated and the characteristics of twisted
line are lost.

DescriptionINFOID:0000000009464681
CAN COMMUNICATION
CAN (Controller Area Network) is a serial communication
line for real time applications. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Modern
vehicle is equipped with many electronic control units , 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, CAN-L) allowing a hi gh rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads the required data only.
CAN communication signal chart. Refer to LAN-32, "CAN COMMUNICATION SYSTEM : CAN Communica-
tion Signal Chart".
ITS COMMUNICATION
• ITS communication is a multiplex communication system . This enables the system to transmit and receive
large quantities of data at high speed by connecting control units with 2 communication lines.
• ITS communication lines adopt twisted-pair line st yle (two lines twisted) for noise immunity.

• When removing or disassembling each component, be careful not to damage or deform it. If a component may be subject to interference, be sure to protect it with a shop cloth.
• When removing (disengaging) components with a screwdriver or similar tool, be sure to wrap the component with a shop cloth or vinyl tape to protect it.
• Protect the removed parts with a s hop cloth and prevent them from being dropped.
• Replace a deformed or damaged clip.
• If a part is specified as a non-reusable part, always replace it with a new one.
• Be sure to tighten bolts and nuts securely to the specified torque.
• After installation is complete, be sure to check that each part works properly.
• Follow the steps below to clean components:
- Water soluble dirt:
• Dip a soft cloth into lukewarm water, wring the water out of the cloth and wipe the dirty area.
• Then rub with a soft, dry cloth.
- Oily dirt:
• Dip a soft cloth into lukewarm water with mild detergent (concentration: within 2 to 3%) and wipe the dirty area.
• Then dip a cloth into fresh water, wring the water out of the cloth and wipe the detergent off.
• Then rub with a soft, dry cloth.
- Do not use organic solvent such as thinner, benzene, alcohol or gasoline.
- For genuine leather seats, use a genuine leather seat cleaner.

SYSTEM
FUNCTION DESCRIPTION
• Lane Departure Warning (LDW) system provides a
lane departure warning function when the vehicle is
driven at speeds of approximately 70 km/h (45 MPH) or more.
• When the vehicle approaches either the left or the ri ght side of the traveling lane, a warning will sound and
the lane departure warning lamp (orange) on the combination meter will blink to alert the driver.
• The warning does not occur during turn signal operation (Lane change side).
• The warning function will stop when the vehicle returns inside of the lane markers.
EXAMPLE
When the vehicle approaches the right lane marker, the driv er is alerted by the buzzer and the blinking of lane
departure warning lamp (orange).
OPERATION DESCRIPTION
• When the system is turned ON by operating the warning systems switch, ITS control unit turns ON the warn-
ing systems ON indicator.
• Rear view camera monitors lane markers of the trav eling lane. It transmits the detected lane condition signal
to ITS control unit via ITS communication.
• When judging from a lane marker detection signal that the vehicle is approaching the lane marker, the ITS
control unit controls the following item to alert the driver.
- Activates warning buzzer
- ITS control unit transmits a lane departure warning lamp signal to combination meter via CAN communica- tion and turns ON/OFF the lane departure warning lamp (orange).
OPERATING CONDITION
• Warning systems ON indicator: ON
• Vehicle speed: approximately 70 km/h (45 MPH) or more
• Turn indicator signal: After 2 seconds or more from turned OFF
NOTE:
• When the LDW system setting on the vehicle information display is ON.
• After the operating conditions of warning are satisfi ed, the warning continues until the vehicle speed reaches
approximately 60 km/h (40 MPH)
• The LDW system may not function properly, depending on the situation. Refer to DAS-82, "Precautions for
Lane Departure Warning"
