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 of
customer's comments; refer to

EXT-7, "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 cruise test on 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 bumblebee)

Buzz characteristics include high frequency rattle/firm contact.

• Often the degree of acceptable noise level will vary depending up on the person. A noise that a technician

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

SBT842

Revision: 2012 November

EXT-4

< SYMPTOM DIAGNOSIS >

SQUEAK AND RATTLE TROUBLE DIAGNOSES

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:
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 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 is are suspected to be the cause of the noise.

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 is are suspected to be the cause of the noise.

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

• 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

EXT-5, "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 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 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

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.

Inspection Procedure

INFOID:0000000009161543

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 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 following:

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. 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 look for the following:
1.

Trunk lid dumpers out of adjustment

Trunk lid striker out of adjustment

Revision: 2012 November

2014 GT-R

EXT-6

< SYMPTOM DIAGNOSIS >

SQUEAK AND RATTLE TROUBLE DIAGNOSES

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 seats 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.
Cause 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.

PRECAUTIONS

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

INFOID:0000000009161545

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 AIR BAG” and “SEAT BELT” of this
Service Manual.

WARNING:

Always observe the following items for preventing accidental activation.
• To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in

the event of a collision that 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 “SRS AIR BAG”.

• 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

WARNING:

Always observe the following items for preventing accidental activation.
• When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the

ignition ON or engine running, never 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.

Aluminum Die-Casting Parts Handling

INFOID:0000000009161546

PROHIBITION OF WELDING OR BEATING REPAIR

• Material made of aluminum die-casting parts is heat-treated and looses strength when being exposed to

welding heat. Do not perform welding repair for cracks, damage or others.

• For aluminum die-casting parts deformation, do not perform repair by beating. Always repair by replacement

as an assembly.

CRACK CHECK

When the vehicle is damaged, always perform a visual deformation check and a crack check.

Crack Check Procedures

For a crack check, use dye penetrant inspection fluid (pre-cleaning fluid, penetrant fluid and developer fluid).

CAUTION:

Always perform a crack check in accordance with the procedures specified by the manufacturer of the
dye penetrant inspection fluid.
1.

Spray pre-cleaning fluid on the checking surface for cleaning.

Spray penetrant fluid on the checking surface and wait until the penetrant fluid soaks into any cracks.

Wipe off excessive penetrant fluid, and then also lightly wipe off penetrant fluid using a wet cloth.

Spray developer fluid on the checking surface.

Cracks, if any, are dyed red in color.

STRAY CURRENT CORROSION

Revision: 2012 November

2014 GT-R

EXT-10

< PRECAUTION >

PRECAUTIONS

• Corrosion occurs to aluminum die-casting parts by the stray current corrosion phenomenon, when directly

contacting other parts made of steel. Always apply anti-stray current corrosion paint (primer) on the mount-
ing surface.

• Clean mounting surface to prevent any foreign matter, steel powder or others from being mixed in. Always

apply the specified adhesive when installing.

• Corrosion by stray current corrosion may occur when installing with any other bolts than the specified bolt.

Always use the specified bolt that is surface treated.

• When loosening the specified bolt that is tightened, the treated surface may peel. Never reuse the specified

bolt that is tightened once.

TIGHTENING TORQUE CONTROL

Material made of aluminum die-casting parts is soft in term of hardness. Tightening torque must be controlled
exactly as specified. Always use a torque wrench to install any part to the specified tightening torque.

WARNING:

Never use a power tool to remove or tighten bolts for aluminum die-casting part to prevent damage to
aluminum die-casting parts.

Precautions Necessary for Steering Wheel Rotation After Battery Disconnection

INFOID:0000000009161547

CAUTION:

Comply with the following cautions to prevent any error and malfunction.
• Before removing and installing any control units, first turn the ignition switch to the LOCK position,

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 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.

For vehicle with 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 operation pro-
cedure below before starting the repair operation.

OPERATION PROCEDURE

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

Turn the 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 ignition switch from ACC position to ON position, then to LOCK position. (The steering wheel will lock
when the ignition switch is turned to LOCK position.)

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

Precaution for Battery Service

INFOID:0000000009161548

Before disconnecting the battery, lower both the driver and passenger windows. This will prevent any interfer-
ence between the window edge and the vehicle when the door is opened/closed. During normal operation, the
