Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT 
PRE-TENSIONER"

INFOID:0000000009881977

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 SR 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 performed by

an authorized NISSAN/INFINITI dealer.

• Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal

injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag

Module, see the SR 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 har-

ness connectors.

PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS

WARNING:

• When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Igni-

tion ON or engine running, DO NOT use air or electric power tools or strike near the sensor(s) with a

hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing

serious injury.

• When using air or electric power tools or hammers, always switch the Ignition OFF, disconnect the

battery, and wait at least 3 minutes before performing any service.

Precaution for Work

INFOID:0000000009881978

• When removing or disassembling each component, be careful not to damage or deform it. If a component

may be subject to interference, be sure to protect it with a shop cloth.

• When removing (disengaging) components with a screwdriver or similar tool, be sure to wrap the component

with a shop cloth or vinyl tape to protect it.

• Protect the removed parts with a shop cloth and prevent them from being dropped.

• Replace a deformed or damaged clip.

• If a part is specified as a non-reusable part, always replace it with a new one.

• Be sure to tighten bolts and nuts securely to the specified torque.

• After installation is complete, be sure to check that each part works properly.

• Follow the steps below to clean components:

- Water soluble dirt:

• Dip a soft cloth into lukewarm water, wring the water out of the cloth and wipe the dirty area.

• Then rub with a soft, dry cloth.

- Oily dirt:

• Dip a soft cloth into lukewarm water with mild detergent (concentration: within 2 to 3%) and wipe the dirty

area.

• Then dip a cloth into fresh water, wring the water out of the cloth and wipe the detergent off.

• Then rub with a soft, dry cloth.

- Do not use organic solvent such as thinner, benzene, alcohol or gasoline.

- For genuine leather seats, use a genuine leather seat cleaner.

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 

IP-8, "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 surfaces

= 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 depen-

dent 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 brought 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.

If possible, drive the vehicle with the customer until the noise is duplicated. Note any additional information on

the Diagnostic Worksheet regarding the conditions or location of the noise. This information can be used to

duplicate the same conditions when you confirm the repair.

If the noise can be duplicated easily during the test drive, to help identify the source of the noise, try to dupli-

cate the noise with the vehicle stopped by doing one or all of the following:

1) Close a door.

2) Tap or push/pull around the area where the noise appears to be coming from.

3) Rev the engine.

4) Use a floor jack to recreate vehicle “twist”.

5) At idle, apply engine load (electrical load, half-clutch on M/T model, drive position on CVT and A/T models).

6) Raise the vehicle on a hoist and hit a tire with a rubber hammer.

• Drive the vehicle and attempt to duplicate the conditions the customer states exist when the noise occurs.

• If it is difficult to duplicate the noise, drive the vehicle slowly on an undulating or rough road to stress the

vehicle body.

CHECK RELATED SERVICE BULLETINS

After verifying the customer concern or symptom, check ASIST for Technical Service Bulletins (TSBs) related

to that concern or symptom.

If a TSB relates to the symptom, follow the procedure to repair the noise.

LOCATE THE NOISE AND IDENTIFY THE ROOT CAUSE

1. Narrow down the noise to a general area. To help pinpoint the source of the noise, use a listening tool

(Chassis Ear: J-39570, Engine Ear: J-39565 and mechanic's stethoscope).

2. Narrow down the noise to a more specific area and identify the cause of the noise by:

• removing the components in the area that you suspect the noise is coming from.

Do not use too much force when removing clips and fasteners, otherwise clips and fasteners can be

broken or lost during the repair, resulting in the creation of new noise.

• tapping or pushing/pulling the component that you suspect is causing the noise.

Do not tap or push/pull the component with excessive force, otherwise the noise will be eliminated only

temporarily.

• feeling for a vibration with your hand by touching the component(s) that you suspect is (are) causing the

noise.

• placing a piece of paper between components that you suspect are causing the noise.

• looking for loose components and contact marks.

Refer to 

IP-6, "Generic Squeak and Rattle Troubleshooting"

.

REPAIR THE CAUSE 

• If the cause is a loose component, tighten the component securely.

• If the cause is insufficient clearance between components:

- separate components by repositioning or loosening and retightening the component, if possible.

- insulate components with a suitable insulator such as urethane pads, foam blocks, felt cloth tape or urethane

tape. A NISSAN Squeak and Rattle Kit (J-43980) is available through your authorized NISSAN Parts Depart-

ment.

CAUTION:

Do not use excessive force as many components are constructed of plastic and may be damaged.

Always check with the Parts Department for the latest parts information.
