PRECAUTIONS
PRECAUTIONS PFP:00001
A
Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT
BELT PRE-TENSIONER" EIS002UD
The Supplemental Restraint System such as "AIR BAG" and "SEAT BELT PRE-TENSIONER", used along B
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 C
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: D
G 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. E
G 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. F
G 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.
G
Handling for Adhesive and Primer EIS002UE
G Do not use an adhesive which is past its usable date. Shelf life of this product is limited to six months after
the date of manufacture. Carefully adhere to the expiration or manufacture date printed on the box. H
G Keep primers and adhesive in a cool, dry place. Ideally, they should be stored in a refrigerator.
G Open the seal of the primer and adhesive just before application. Discard the remainder.
GW
G Before application, be sure to shake the primer container to stir the contents. If any floating material is
found, do not use it.
G If any primer or adhesive contacts the skin, wipe it off with gasoline or equivalent and wash the skin with
J
soap.
G When using primer and adhesive, always observe the precautions in the instruction manual.
Trouble Diagnosis Precaution EIS002UF K
When you read wiring diagrams, refer to the following:
G GI-15, "How to Read Wiring Diagrams".
L
G PG-4, "POWER SUPPLY ROUTING CIRCUIT".
When you perform trouble diagnosis, refer to the following:
G GI-11, "HOW TO FOLLOW TEST GROUPS IN TROUBLE DIAGNOSES". M
G GI-27, "How to Perform Efficient Diagnosis for an Electrical Incident".
Check for any service bulletins before servicing the vehicle.

CUSTOMER INTERVIEW
Interview the customer if possible, to determine the conditions that exist when the noise occurs. Use the Diag- H
nostic Worksheet during the interview to document the facts and conditions when the noise occurs and any
customer's comments; refer to GW-9, "Diagnostic Worksheet" . This information is necessary to duplicate the
conditions that exist when the noise occurs.
GW
G 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).
G If there is more than one noise in the vehicle, be sure to diagnose and repair the noise that the customer
J
is concerned about. This can be accomplished by test driving the vehicle with the customer.
G 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. K
G 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. L
G 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. M
G 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.
G Knock --(Like a knock on a door)
Knock characteristics include hollow sounding/sometimes repeating/often brought on by driver action.
G 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.
G Thump--(Heavy, muffled knock noise)
Thump characteristics include softer knock/dead sound often brought on by activity.
G Buzz--(Like a bumble bee)
Buzz characteristics include high frequency rattle/firm contact.
G 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.
G Weather conditions, especially humidity and temperature, may have a great effect on noise level.
Revision: August 2007 GW-5 2004 QX56
SQUEAK AND RATTLE TROUBLE DIAGNOSES
DUPLICATE THE NOISE AND TEST DRIVE
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 A/T model).
6) Raise the vehicle on a hoist and hit a tire with a rubber hammer.
G Drive the vehicle and attempt to duplicate the conditions the customer states exist when the noise occurs.
G 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:
G 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 bro-
ken or lost during the repair, resulting in the creation of new noise.
G 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.
G feeling for a vibration with your hand by touching the component(s) that you suspect is (are) causing the
noise.
G placing a piece of paper between components that you suspect are causing the noise.
G looking for loose components and contact marks.
Refer to GW-7, "Generic Squeak and Rattle Troubleshooting" .
REPAIR THE CAUSE
G If the cause is a loose component, tighten the component securely.
G If the cause is insufficient clearance between components:
