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.

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 Work

NIS0015O

●

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

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-11, "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 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.

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.

●

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

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 and mechanics stethoscope).

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 fastener 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

BL-9, "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 ure-
thane tape. A Nissan Squeak and Rattle Kit (J-43980) is available through your authorized Nissan Parts
Department.

CAUTION:

Do not use excessive force as many components are constructed of plastic and may be damaged.
NOTE:
Always check with the Parts Department for the latest parts information.
The following materials are contained in the Nissan Squeak and Rattle Kit (J-43980). Each item can be

CONFIRM THE REPAIR

Confirm that the cause of a noise is repaired by test driving the vehicle. Operate the vehicle under the same
conditions as when the noise originally occurred. Refer to the notes on the Diagnostic Worksheet.

Generic Squeak and Rattle Troubleshooting

NIS0015T

Refer to Table of Contents for specific component removal and installation information.

INSTRUMENT PANEL

Most incidents are caused by contact and movement between:

The cluster lid A and instrument panel

Acrylic lens and combination meter housing

Instrument panel to front pillar garnish

Instrument panel to windshield

Instrument panel mounting pins

Wiring harnesses behind the combination meter

A/C defroster duct and duct joint

These incidents can usually be located by tapping or moving the components to duplicate the noise or by
pressing on the components while driving to stop the noise. Most of these incidents can be repaired by apply-
ing felt cloth tape or silicon spray (in hard to reach areas). Urethane pads can be used to insulate wiring har-
ness.

CAUTION:

Do not use silicone spray to isolate a squeak or rattle. If you saturate the area with silicone, you will
not be able to recheck the repair.

CENTER CONSOLE

Components to pay attention to include:

Shifter assembly cover to finisher

A/C control unit and cluster lid C

Wiring harnesses behind audio and A/C control unit

The instrument panel repair and isolation procedures also apply to the center console.

DOORS

Pay attention to the:

Finisher and inner panel making a slapping noise

Inside handle escutcheon to door finisher

Wiring harnesses tapping

Door striker out of alignment causing a popping noise on starts and stops

Tapping or moving the components or pressing on them while driving to duplicate the conditions can isolate
many of these incidents. You can usually insulate the areas with felt cloth tape or insulator foam blocks from
the Nissan Squeak and Rattle Kit (J-43980) to repair the noise.

TRUNK

Trunk noises are often caused by a loose jack or loose items put into the trunk by the owner.
In addition look for:
1.

Trunk lid dumpers out of adjustment

Trunk lid striker out of adjustment

The trunk lid torsion bars knocking together

A loose license plate or bracket

Most of these incidents can be repaired by adjusting, securing or insulating the item(s) or component(s) caus-
ing the noise.

SUNROOF/HEADLINING

Noises in the sunroof/headlining area can often be traced to one of the following:

Sunroof lid, rail, linkage or seals making a rattle or light knocking noise

Sunvisor shaft shaking in the holder

Front or rear windshield touching headlining and squeaking

Again, pressing on the components to stop the noise while duplicating the conditions can isolate most of these
incidents. Repairs usually consist of insulating with felt cloth tape.

SEATS

When isolating seat noise it's important to note the position the seat is in and the load placed on the seat when
the noise is present. These conditions should be duplicated when verifying and isolating the cause of the
noise.
Cause of seat noise include:

Headrest rods and holder

A squeak between the seat pad cushion and frame

The rear seatback lock and bracket

These noises can be isolated by moving or pressing on the suspected components while duplicating the con-
ditions under which the noise occurs. Most of these incidents can be repaired by repositioning the component
or applying urethane tape to the contact area.

UNDERHOOD

Some interior noise may be caused by components under the hood or on the engine wall. The noise is then
transmitted into the passenger compartment.
Causes of transmitted underhood noise include:
1.

Any component mounted to the engine wall

Components that pass through the engine wall

Engine wall mounts and connectors

Loose radiator mounting pins

Hood bumpers out of adjustment

Hood striker out of adjustment

These noises can be difficult to isolate since they cannot be reached from the interior of the vehicle. The best
method is to secure, move or insulate one component at a time and test drive the vehicle. Also, engine RPM
or load can be changed to isolate the noise. Repairs can usually be made by moving, adjusting, securing, or
insulating the component causing the noise.

Remove hood lock assembly, loosen the hood hinge nuts and close the hood.

Adjust the lateral and longitudinal clearance, and open the hood to tighten the hood hinge mounting bolts
to the specified torque.

Install the hood lock temporarily, and align the hood striker and lock so that the centers of striker and lock
become vertical viewed from the front, by moving the hood lock laterally.

Tighten hood lock mounting bolts to the specified torque.

CAUTION:

Adjust right/left Clearance between hood and each part to the following specification.

FRONT END HEIGHT ADJUSTMENT

Remove the hood lock and adjust the height by rotating the bumper rubber until the hood becomes 1 to1.5
mm (0.04 to 0.059 in) lower than the fender.

Temporarily tighten the hood lock, and position it by engaging it with the hood striker. Check the lock and
striker for looseness, and tighten the hood lock mounting bolts to the specified torque.

SURFACE HEIGHT ADJUSTMENT

Remove hood lock, and adjust the surface height difference of hood, fender and headlamp according to
the fitting standard dimension, by rotating RH and LH bumper rubbers.

Install hood lock temporarily, and move hood lock laterally until the centers of striker and lock become ver-
tical when viewed from the front.

Make sure that the hood lock secondary latch is properly
engaged with the secondary striker with hood's own weight.

Make sure that the hood lock primary latch is securely engaged
with the hood striker with hood's own weight by dropping hood
from approx. 200 mm(7.87in) height.

CAUTION:

Do not drop hood from a height of 300 mm (11.81 in) or
more.

Move hood lockup and down until striker smoothly engages the
lock when the hood is closed.

When pulling the hood opener lever gently, make sure that front
end of the hood rises by approximately 20 mm (0.79 in) and that hood striker and hood lock primary latch
is disengaged. Also make sure that hood opener returns to the original position.
