PRECAUTIONS

PFP:00001

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT 
BELT PRE-TENSIONER”

AKS007PK

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:

●

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 When Using CONSULT-II

AKS004YM

When connecting CONSULT-II to data link connector, connect them through CONSULT-II CONVERTER.

CAUTION:

If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carry out CAN communication.

CHECK POINTS FOR USING CONSULT-II

1.

Has CONSULT-II been used without connecting CONSULT-II CONVERTER on this vehicle?

–

If YES, GO TO 2.

–

If NO, GO TO 5.

2.

Is there any indication other than indications relating to CAN communication system in the self-diagnosis
results?

–

If YES, GO TO 3.

–

If NO, GO TO 4.

3.

Based on self-diagnosis results unrelated to CAN communication, carry out the inspection.

4.

Malfunctions may be detected in self-diagnosis depending on control units carrying out CAN communica-
tion. Therefore, erase the self-diagnosis results.

5.

Diagnose CAN communication system. Refer to 

LAN-12, "CAN Communication Unit For 2WD Models"

  or

LAN-23, "CAN Communication Unit For AWD Models"

 .

Precautions For Trouble Diagnosis

AKS004YN

CAN SYSTEM

●

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

●

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

●

Be sure to turn ignition switch off and disconnect negative battery terminal before checking the circuit.

Precautions For Harness Repair

AKS004YO

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

PFP:23710

System Description

AKS004YP

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.
