Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000006700744
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. Information necessary to service the system safely is included in the “SRS AIR BAG” and
“SEAT BELT” of this Service Manual.
The vehicle may be equipped with a passenger air bag deactivation switch. Because no rear seat exists where
a rear-facing child restraint can be placed, the switch is designed to turn off the passenger air bag so that a
rear-facing child restraint can be used in the front passenger seat. The switch is located in the center of the
instrument panel, near the ashtray. When the switch is turned to the ON position, the passenger air bag is
enabled and could inflate for certain types of collision. When the switch is turned to the OFF position, the pas-
senger air bag is disabled and will not inflate. A passenger air bag OFF indicator on the instrument panel lights
up when the passenger air bag is switched OFF. The driver air bag always remains enabled and is not affected
by the passenger air bag deactivation switch.
WARNING:
• 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 performed by
an authorized NISSAN/INFINITI dealer.
• Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal
injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see the “SRS AIR BAG”.
• 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 har-
ness connectors.
• The vehicle may be equipped with a passenger air bag deactivation switch which can be operated by
the customer. When the passenger air bag is switched OFF, the passenger air bag is disabled and
will not inflate. When the passenger air bag is switched ON, the passenger air bag is enabled and
could inflate for certain types of collision. After SRS maintenance or repair, make sure the passenger
air bag deactivation switch is in the same position (ON or OFF) as when the vehicle arrived for ser-
vice.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
• When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the
ignition ON or engine running, DO NOT use air or electric 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 3 minutes before performing any service.
Precautions for Trouble Diagnosis
INFOID:0000000006415113
CAUTION:
• Never apply 7.0 V or more to the measurement terminal.
• Use a tester with open terminal voltage of 7.0 V or less.
• Turn the ignition switch OFF and disconnect the battery cable from the negative terminal when
checking the harness.

PRECAUTIONS
Precautions for Harness Repair
INFOID:0000000006415114
• 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 CAN communication error. The
spliced wire becomes separated and the characteristics of twisted
line are lost.
• Replace the applicable harness as an assembly if error is detected on the shield lines of CAN communica-
tion line.

CAN COMMUNICATION SYSTEM
CAN COMMUNICATION SYSTEM : System Diagram
INFOID:0000000006415098
CAN COMMUNICATION SYSTEM : System Description
INFOID:0000000006444181
Description
• CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle
multiplex communication line with high data communication speed and excellent error detection ability. Many
electronic 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 communication lines (CAN-H line, CAN-L line) allowing a high rate of information transmission with
less wiring. Each control unit transmits/receives data but selectively reads required data only.
• Termination circuits (resistors) are connected across the CAN communication system. When transmitting a
CAN communication signal, each control unit passes a current to the CAN-H line and the current returns to
the CAN-L line. The current flows separately into the termination circuits connected across the CAN commu-
nication system and the termination circuits drop voltage to generate a potential difference between the
CAN-H line and the CAN-L line. The system produces digital signals for signal communications, by using the
potential difference.
CAN Communication Line
JSMIA0449GB
JSMIA0450GB
LAN-28
< SYSTEM DESCRIPTION >
[CAN]
SYSTEM
The CAN communication line is a twisted pair wire consisting of
strands of CAN-L (1) and CAN-L (2) and has noise immunity.
NOTE:
The CAN communication system has the characteristics of noise-resistant because this system produces dig-
ital signals by using the potential difference between the CAN-H line and the CAN-L line and has the twisted
pair wire structure.
Since the CAN-H line and the CAN-L line are always adjacent to
each other, the same degree of noise occurs, respectively, when a
noise (1) occurs. Although the noise changes the voltage, the poten-
tial difference (2) between the CAN-H line and the CAN-L line is
insensitive to noise. Therefore, noise-resistant signals can be
obtained.
CAN Signal Communications
Each control unit of the CAN communication system transmits signals through the CAN communication con-
trol circuit included in the control unit and receives only necessary signals from each control unit to perform
various kinds of control.
• Example: Transmitted signals
