Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
NKS003XO
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.
WAR NING :
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-IINKS003XP
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-9, "
TROUBLE DIAGNOSES WORK FLOW" .
Precautions For Trouble DiagnosisNKS003XQ
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
Revision: 2006 January2006 M35/M45
Precautions For Harness RepairNKS003XR
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.)

WHEN A MALFUNCTION IS DETECTED BY CAN COMMUNICATION SYSTEM
CAN communication line is open. (CAN H, CAN L, or both)
CAN communication line is shorted. (Ground, between CAN lines, or other harnesses)
The areas related to CAN communication of unit is malfunctioning.
WHEN A MALFUNCTION IS DETECTED EXCEPT CAN COMMUNICATION SYSTEM
Removal and installation of parts: When the units that perform CAN communication or the sensors related
to CAN communication are removed and installed, malfunction may be detected (or DTC other than CAN
communication may be detected).
Fuse blown out (removed): CAN communication of the unit may be stopped at such time.
Low voltage: If the voltage decreases because of battery discharge when IGN is ON, malfunction may be
detected by self-diagnosis according to the units.

TROUBLE DIAGNOSIS FLOW CHART
Depending on the control unit which performs CAN communication, “U1010” may be indicated as the result of
self-diagnosis. Replace the control unit if “U1010” is indicated.
Step 1: Refer to LAN-11, "SELECTING CAN SYSTEM TYPE (HOW TO USE SPECIFICATION TABLE)" .
Step 2: Refer to LAN-12, "ACQUISITION OF DATA BY CONSULT-II" .
Step 3: Refer to LAN-14, "HOW TO USE CHECK SHEET TABLE" .
Step 4: Refer to LAN-15, "Example of Filling in Check Sheet When Initial Conditions Are Reproduced" .
Step 5: Check and repair according to system diagnosis.
