NORMAL OPERATING CONDITION
Description
INFOID:0000000007347784
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, AV control unit malfunc-
tion
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

PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000007347785
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:0000000007347786
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 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.

6. Perform a self-diagnosis check of all control units using CONSULT.
Precaution for Work
INFOID:0000000007347787
• 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.
