[CAN]PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EKS001U0
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 and SB section of
this Service Manual.
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 per-
formed by an authorized NISSAN/INFINITI dealer.

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.

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 Trouble DiagnosisEKS001U1
CAN SYSTEM

Do not apply voltage of 7.0 V or higher to the measurement terminals.

Use the tester with its open terminal voltage being 7.0 V or less.

Be sure to turn ignition switch off and disconnect the battery cable from the negative terminal before
checking the circuit.
Precautions For Harness RepairEKS001U2
CAN SYSTEM

Solder the repaired parts, and wrap with tape. [Frays of twisted
line must be within 110 mm (4.33 in).]

Do not perform bypass wire connections for the repair parts.
(The spliced wire will become separated and the characteristics
of twisted line will be lost.)

CAN COMMUNICATION

CAN COMMUNICATIONPFP:23710
System DescriptionEKS001U3
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.
