PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EHS001Y8
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:
lTo 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.
lImproper 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.
lDo 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 SRS “AIR BAG” and “SEAT BELT PRE-TENSIONER” ServiceEHS001Y9
lDo not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
lBefore servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 min-
utes.
For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt
pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes
have passed.
lDiagnosis sensor unit must always be installed with their arrow marks “Ü” pointing towards the front of the
vehicle for proper operation. Also check diagnosis sensor unit for cracks, deformities or rust before instal-
lation and replace as required.
lThe spiral cable must be aligned with the neutral position since its rotations are limited. Do not attempt to
turn steering wheel or column after removal of steering gear.
lHandle air bag module carefully. Always place driver and front passenger air bag modules with the pad
side facing upward and place front side air bag module standing with stud bolt side setting bottom.
lConduct self-diagnosis to check entire SRS for proper function after replacing any components.
lAfter air bag inflates, the front instrument panel assembly should be replaced if damaged.
lAlways replace instrument panel pad following front passenger air bag deployment.
Precautions for Trouble DiagnosisEHS001YA
When you read wiring diagrams, refer to the following:
lGI-15, "How to Read Wiring Diagrams"in GI section
lPG-4, "POWER SUPPLY ROUTING CIRCUIT"in PG section
When you perform trouble diagnosis, refer to the following:
lGI-11, "How to Follow Trouble Diagnoses"in GI section
lGI-24, "How to Perform Efficient Diagnosis for an Electrical Incident"in GI section
Check for any service bulletins before servicing the vehicle.

REMOVAL
CAUTION:
lDo not attempt to repair or replace damaged direct-connect SRS component connectors. If a
driver air bag direct-connect harness connector is damaged, the spiral cable must be replaced.
lBefore servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at
least 3 minutes.
lWhen servicing the SRS, do not work from directly in front of air bag module.
1. Locate retaining clip access hole and insert screwdriver.
2. Press upward (toward center of steering wheel) on retaining clip until driver air bag module is released
from steering wheel.
3. Lift the driver air bag module from the steering wheel.

6. Remove the screws. Then while pressing the tab, pull the spiral
cable away from steering column assembly.
CAUTION:
lDo not disassemble spiral cable.
lDo not apply lubricant to the spiral cable.
7. Disconnect the spiral cable connectors.
CAUTION:
With the steering linkage disconnected, the spiral cable
may snap by turning the steering wheel beyond the limited
number of turns. The spiral cable can be turned counter-
clockwise about 2.5 turns from the right end position.
INSTALLATION
Install in the reverse order of removal.
lAlign spiral cable correctly when installing steering wheel, refer
toSRS-39, "
INSTALLATION". Make sure that the spiral cable is
in the neutral position. The neutral position is detected by turn-
ing left 2.6 revolutions from the right end position and ending
with the locating pin at the top.
lReset the steering angle sensor calibration after installing spiral
cable.
lAfter the work is completed, perform self-diagnosis to make sure
no malfunction is detected. Refer toSRS-18, "
SRS Operation
Check".
CAUTION:
lThe spiral cable may snap due to steering operation if the
cable is not installed in the correct position.
lWith the steering linkage disconnected, the cable may snap by turning the steering wheel beyond
the limited number of turns. The spiral cable can be turned counterclockwise about 2.5 turns from
the right end position.
