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 comments. Refer to

IP-6, "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, perform a diagnosis and repair the noise that the customer is

concerned about. This can be accomplished by performing a test drive with the customer.

• After identifying the type of noise, isolate the noise in terms of its characteristics. The noise characteristics

are provided so that the customer, service adviser, and technician use the same language when describing
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 = high-pitched noise / softer surfaces = low-pitched 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 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 sounds / 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 / dull sounds often brought on by activity.

• Buzz – (Like a bumblebee)

Buzz characteristics include high frequency rattle / firm contact.

• Often the degree of acceptable noise level varies depending upon the person. A noise that a technician may

judge as acceptable may be very irritating to a customer.

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

DUPLICATE THE NOISE AND TEST DRIVE

SQUEAK AND RATTLE TROUBLE DIAGNOSES

IP-3

< SYMPTOM DIAGNOSIS >

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 the repair is reconfirmed.
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 items:
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 models, drive position on 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 the 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 component(s) in the area that is / are suspected to be the cause of the noise.

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(s) that is / are suspected to be the cause of the noise.

Do not tap or push/pull the component(s) with excessive force, otherwise the noise is eliminated only tempo-
rarily.

• Feeling for a vibration by hand by touching the component(s) that is / are suspected to be the cause of the

noise.

• Placing a piece of paper between components that are suspected to be the cause of the noise.
• Looking for loose components and contact marks.

Refer to

IP-4, "Inspection Procedure"

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 components, 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 the authorized NISSAN Parts
Department.

CAUTION:

Never 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
ordered separately as needed.

CONFIRM THE REPAIR

After repair is complete, test drive the vehicle to confirm that the cause of 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.

Inspection Procedure

INFOID:0000000004754829

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
applying felt cloth tape or silicon spray (in hard to reach areas). Urethane pads can be used to insulate
wiring harness.

CAUTION:

Never use silicone spray to isolate a squeak or rattle. If the area is saturated with silicone, the
recheck of repair becomes impossible.

CENTER CONSOLE

Components to check 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

Check the following items:

Finisher and inner panel making a slapping noise

Inside handle escutcheon connection to door finisher

Wiring harnesses tapping

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

Tapping, moving the components, or pressing on them while driving to duplicate the conditions can isolate
many of these incidents. The areas can usually be insulated 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 customer.
In addition check for the following items:

Revision: 2008 October

2009 Murano

SQUEAK AND RATTLE TROUBLE DIAGNOSES

IP-5

< SYMPTOM DIAGNOSIS >

Trunk lid dumpers out of adjustment

Trunk lid striker out of adjustment

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 items:

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 is important to note the position the seat is in and the load placed on the seat
when the noise occurs. These conditions should be duplicated when verifying and isolating the cause of the
noise.
Causes of seat noise include:
1.

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:

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.

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

INFOID:0000000004754831

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 AIRBAG” and “SEAT BELT” 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 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 “SRS AIRBAG”.

• Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Ser-

vice Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness
connectors.

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

When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors while ignition switch is
ON or engine is running, never use air or electric power tools or strike near the sensor(s) with a hammer.
Heavy vibration may activate the sensor(s), deploy the airbag(s), possibly cause serious injury.
When using air or electric power tools or hammers, always turn OFF ignition switch, disconnect the battery,
and wait 3 minutes or more before performing any service.

Precaution Necessary for Steering Wheel Rotation after Battery Disconnect

INFOID:0000000004754887

NOTE:
• Before removing and installing any control units, first turn the push-button ignition switch to the LOCK posi-

tion, then disconnect both battery cables.

• After finishing work, confirm that all control unit connectors are connected properly, then re-connect both

battery cables.

• Always use CONSULT-III to perform self-diagnosis as a part of each function inspection after finishing work.

If a DTC is detected, perform trouble diagnosis according to self-diagnosis results.

This vehicle is equipped with a push-button ignition switch and a steering lock unit.
If the battery is disconnected or discharged, the steering wheel will lock and cannot be turned.
If turning the steering wheel is required with the battery disconnected or discharged, follow the procedure
below before starting the repair operation.

OPERATION PROCEDURE

Connect both battery cables.
NOTE:
Supply power using jumper cables if battery is discharged.

Turn the push-button ignition switch to ACC position.
(At this time, the steering lock will be released.)

Disconnect both battery cables. The steering lock will remain released with both battery cables discon-
nected and the steering wheel can be turned.

Perform the necessary repair operation.

When the repair work is completed, re-connect both battery cables. With the brake pedal released, turn
the push-button ignition switch from ACC position to ON position, then to LOCK position. (The steering
wheel will lock when the push-button ignition switch is turned to LOCK position.)

Perform self-diagnosis check of all control units using CONSULT-III.
