DEPLOYMENT OF AIR BAG MODULE AND SEAT BELT PRE-TENSIONER WHILE MOUNTED IN
VEHICLE
When disposing of a vehicle, deploy air bag module and seat belt pre-tensioners while they are mounted in
vehicle.
CAUTION:
When deploying air bag module or seat belt pre-tensioner, ensure vehicle is empty.
1. Disconnect both battery cables and wait 3 minutes.
2. Disconnect air bag module and seat belt pre-tensioner connector.
3. Connect deployment tool (SST: KV99106400) to air bag module or seat belt pre-tensioner.
For driver air bag module, attach deployment tool adapter (SST: KV99109700) to the tool connector.
For front passenger air bag module, attach deployment tool adapter (SST:KV99108300) to the tool con-
nector.
For side air bag module, attach deployment tool adapter (SST: KV99109000) to the tool connector.
For seat belt pre-tensioner, attach deployment tool adapter (SST: KV99109700) to the tool connector.
4. Connect red clip of deployment tool to battery positive terminal
and black clip to negative terminal.
5. The lamp on the right side of the tool, marked “deployment tool
power”, should glow green, not red.
6. Press the button on the deployment tool. The left side lamp on
the tool, marked “air bag connector voltage”, will illuminate and
the air bag module or seat belt pre-tensioner will deploy.
CAUTION:
Activate only one air bag module or seat belt pre-tensioner
at a time.
DISPOSING OF AIR BAG MODULE AND SEAT BELT PRE-TENSIONER
Deployed air bag module and seat belt pre-tensioner are very hot. Before disposing of air bag module and
seat belt pre-tensioner, wait at least 30 minutes, and 10 minutes, respectively. Seal them in a plastic bag
before disposal.
CAUTION:

Never apply water to a deployed air bag module and seat
belt pre-tensioner.

Be sure to wear gloves when handling a deployed air bag
module and seat belt pre-tensioner.

No poisonous gas is produced upon air bag module
deployment. However, be careful not to inhale gas since it
irritates throat and can cause choking.

Do not attempt to disassemble air bag module and seat belt
pre-tensioner.

Air bag module and seat belt pre-tensioner cannot be
reused.

Wash your hands clean after finishing work.

PRECAUTIONS

PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EIS008TY
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 WorkEIS008P8

After removing and installing the opening/closing parts, be sure to carry out fitting adjustments to check
their operation.

Check the lubrication level, damage, and wear of each part. If necessary, grease or replace it.
Wiring Diagnosis and Trouble DiagnosisEIS008P9
When you read wiring diagrams, refer to the following:

GI-14, "How to Read Wiring Diagrams"

PG-2, "POWER SUPPLY ROUTING"
When you perform trouble diagnosis, refer to the following:

GI-10, "HOW TO FOLLOW TEST GROUPS IN TROUBLE DIAGNOSES"

GI-23, "How to Perform Efficient Diagnosis for an Electrical Incident"
Check for any Service bulletins before servicing the vehicle.

SQUEAK AND RATTLE TROUBLE DIAGNOSESPFP:00000
Work FlowEIS008PR
CUSTOMER INTERVIEW
Interview the customer if possible, to determine the conditions that exist when the noise occurs. Use the Diag-
nostic Worksheet during the interview to document the facts and conditions when the noise occurs and any
customer's comments; refer to BL-10, "
Diagnostic Worksheet" . This information is necessary to duplicate the
conditions that exist when the noise occurs.

The customer may not be able to provide a detailed description or the location of the noise. Attempt to
obtain all the facts and conditions that exist when the noise occurs (or does not occur).

If there is more than one noise in the vehicle, be sure to diagnose and repair the noise that the customer
is concerned about. This can be accomplished by test driving the vehicle with the customer.

After identifying the type of noise, isolate the noise in terms of its characteristics. The noise characteristics
are provided so the customer, service adviser and technician are all speaking the same language when
defining the noise.

Squeak —(Like tennis shoes on a clean floor)
Squeak characteristics include the light contact/fast movement/brought on by road conditions/hard sur-
faces=higher pitch noise/softer surfaces=lower pitch noises/edge to surface=chirping

Creak—(Like walking on an old wooden floor)
Creak characteristics include firm contact/slow movement/twisting with a rotational movement/pitch
dependent on materials/often brought on by activity.

Rattle—(Like shaking a baby rattle)
Rattle characteristics include the fast repeated contact/vibration or similar movement/loose parts/missing
clip or fastener/incorrect clearance.

Knock —(Like a knock on a door)
Knock characteristics include hollow sounding/sometimes repeating/often brought on by driver action.

Tick—(Like a clock second hand)
Tick characteristics include gentle contacting of light materials/loose components/can be caused by driver
action or road conditions.

Thump—(Heavy, muffled knock noise)
Thump characteristics include softer knock/dead sound often drought on by activity.

Buzz—(Like a bumble bee)
Buzz characteristics include high frequency rattle/firm contact.

Often the degree of acceptable noise level will vary depending upon the person. A noise that you may
judge as acceptable may be very irritating to the customer.

Weather conditions, especially humidity and temperature, may have a great effect on noise level.
