PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000009749867
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 AIR BAG” and “SEAT BELT” of this
Service Manual.
WARNING:
Always observe the following items for preventing accidental activation.
• To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in
the event of a collision that 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 “SRS AIR BAG”.
• Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Ser-
vice Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness
connectors.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
Always observe the following items for preventing accidental activation.
• When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the
ignition ON or engine running, never 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 Removing of Battery Terminal
INFOID:0000000010199438
• When removing the 12V battery terminal, turn OFF the ignition
switch and wait at least 30 seconds.
NOTE:
ECU may be active for several tens of seconds after the ignition
switch is turned OFF. If the battery terminal is removed before ECU
stops, then a DTC detection error or ECU data corruption may
occur.
• For vehicles with the 2-batteries, be sure to connect the main bat-
tery and the sub battery before turning ON the ignition switch.
NOTE:
If the ignition switch is turned ON with any one of the terminals of
main battery and sub battery disconnected, then DTC may be
detected.
• After installing the 12V battery, always check "Self Diagnosis Result" of all ECUs and erase DTC.
NOTE:
The removal of 12V battery may cause a DTC detection error.
Precautions for Trouble Diagnosis
INFOID:0000000009749868
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.

PRECAUTIONS
• Turn the ignition switch OFF and disconnect the battery cable from the negative terminal when
checking the harness.
Precautions for Harness Repair
INFOID:0000000009749869
• 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 : System Description
INFOID:0000000009749872
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.

The CAN communication line is a twisted pair wire consisting of
strands of CAN-H (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
