DescriptionINFOID:0000000003765606
NOTE:
 Audio operation information, refer to Owner's Manual.
 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 that 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 then determine the cause.
NOTE:
The source of the noise can be easily found by listening to the noise while removing the fuses of electrical
components, one by one.
Types of Noise and Possible Causes
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

PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000003960541
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. 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.
Precaution for Trouble DiagnosisINFOID:0000000003765608
AV COMMUNICATION SYSTEM
 Do not apply voltage of 7.0 V or higher to the measurement terminals.
 Use the tester with its open terminal voltage at 7.0 V or less.
 Turn ignition switch OFF and disconnect the battery cable from the negative terminal before checking the cir-
cuit.
Precaution for Harness RepairINFOID:0000000003765609
AV COMMUNICATION SYSTEM
 Solder the repaired parts, and wrap with tape. [Frays of twisted line
must be within 110 mm (4.33 in).]
 Do not perform bypass wire connections for the repair parts. (The
spliced wire will become separated and the characteristics of
twisted line will be lost.)

Part name Description
AV CONTROL UNIT It is the master unit of the MULTI AV system, and it is connected to each control
unit by communication. It operates each system according to communication
signals from the AV control unit.
 AV control unit includes audio function and vehicle information function.
 It is connected to ECM and combination meter via CAN communication to ob-
tain necessary information for the vehicle information function.
 It is connected to BCM via CAN communication transmitting/receiving for the
vehicle settings function.
 AUX image signal is input from auxiliary jacks.
 Camera image signal is input from camera control unit.
 Composite image (AUX and camera images) signal is output to display unit.
 AUX sound signal is input from the auxiliary jacks.
 Power (signal VCC and inverter VCC) is transmitted to front display unit.
DISPLAY UNIT Display image is controlled by the serial communication from AV control unit.
 It receives the power (signal VCC and inverter VCC) from the AV control unit
and operates.

U1000 CAN COMM CIRCUIT
DescriptionINFOID:0000000003882713
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN-H, CAN-L) allowing a high rate of information transmission with less wiring. Each
control unit transmits/receives data but selectively reads required data only.

CAN Communication Signal Chart".
