PRECAUTIONS
[CAN]
PRECAUTIONS PFP:00001
Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT
BELT PRE-TENSIONER" EKS004AL
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.
Precautions for CAN System EKS0050R
q Do not apply voltage of 7.0V or higher to terminal to be measured.
q Maximum open terminal voltage of tester in use must be less than 7.0V.
q Before checking harnesses, turn ignition switch OFF and disconnect battery negative cable.
q Area to be repaired must be soldered and wrapped with tape.
Make sure that fraying of twisted wire is within 110 mm (4.33 in).
PKIA0306E
q Do not make a bypass connection to repaired area. (If the cir-
cuit is bypassed, characteristics of twisted wire will be lost.)
PKIA0307E
Wiring Diagrams and Trouble Diagnosis EKS0050S
When you read wiring diagrams, refer to the following:
q GI-12, "How to Read Wiring Diagrams"
q PG-3, "POWER SUPPLY ROUTING CIRCUIT"
When you perform trouble diagnosis, refer to the following:
q GI-10, "HOW TO FOLLOW TEST GROUPS IN TROUBLE DIAGNOSES"

CAN COMMUNICATION
[CAN]
CAN COMMUNICATION PFP:23710
System Description EKS004AP
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic 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.
CAN System Type EKS004AQ
Refer to the following table to determine CAN system type.
