an issue with the speaker, usually something nearby 
the speaker is causing the buzz/rattle.

NORMAL OPERATING CONDITION

Description

INFOID:0000000006246518

The majority of the audio concerns are the result of outside causes (bad CD, electromagnetic interference,

etc.).

NOISE

The following noise results from variations in field strength, such as fading noise and multi-path noise, or

external noise from trains and other sources. It is not a malfunction.

• Fading noise: This noise occurs because of variations in the field strength in a narrow range due to moun-

tains or buildings blocking the signal.

• Multi-path noise: This noise results from the waves sent directly from the broadcast station arriving at the

antenna at a different time from the waves which reflect off mountains or buildings.

The vehicle itself can be a source of noise if noise prevention parts or electrical equipment is malfunctioning.

Check if noise is caused and/or changed by engine speed, ignition switch turned to each position, and opera-

tion of each piece of electrical equipment, and determine the cause.

NOTE:

The source of the noise can be found easily by listening to the noise while removing the fuses of electrical

components, one by one.

Type of Noise and Possible Cause

Occurrence condition

Possible cause

Occurs only when engine is ON.

A continuous growling noise occurs. The speed of 
the noise varies with changes in the engine speed.

• Ignition components

The occurrence of the noise is linked with the operation of the fuel pump.

• Fuel pump condenser

Noise only occurs when various 
electrical components are oper-
ating.

A cracking or snapping sound occurs with the op-
eration of various switches.

• Relay malfunction, audio unit malfunction

The noise occurs when various motors are operat-
ing.

• Motor case ground
• Motor

The noise occurs constantly, not just under certain conditions.

• Rear defogger coil malfunction
• Open circuit in printed heater
• Poor ground of antenna feeder line

A cracking or snapping sound occurs while the vehicle is being driven, especially when 
it is vibrating excessively.

• Ground wire of body parts
• Ground due to improper part installation
• Wiring connections or a short circuit

PRECAUTION

PRECAUTIONS

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

INFOID:0000000006246519

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 Necessary for Steering Wheel Rotation After Battery Disconnect

INFOID:0000000006246520

NOTE:

• This Procedure is applied only to models with Intelligent Key system and NATS (NISSAN ANTI-THEFT SYS-

TEM).

• Remove and install all control units after disconnecting both battery cables with the ignition knob in the

″

LOCK

″

 position.

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

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

For models equipped with the Intelligent Key system and NATS, an electrically controlled steering lock mech-

anism is adopted on the key cylinder.

For this reason, if the battery is disconnected or if the battery is discharged, the steering wheel will lock and

steering wheel rotation will become impossible.

If steering wheel rotation is required when battery power is interrupted, follow the procedure below before

starting the repair operation.

OPERATION PROCEDURE

1. Connect both battery cables.

NOTE:

Supply power using jumper cables if battery is discharged.

2. Use the Intelligent Key or mechanical key to turn the ignition switch to the 

″

ACC

″

 position. At this time, the

steering lock will be released.

3. Disconnect both battery cables. The steering lock will remain released and the steering wheel can be

rotated.

4. Perform the necessary repair operation.

″

 position before connecting

the battery cables. (At this time, the steering lock mechanism will engage.)

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

Precaution for Work

INFOID:0000000006832783

• 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 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, and wring the water out of the cloth to wipe the dirty

area.

Then rub with a soft and 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, and wring the water out of the cloth to wipe the detergent off. Then rub with

a soft and dry cloth.

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

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