BASIC OPERATIONS
RELATED TO AUDIO
 The majority of the audio malfunctions are the result of outside causes (bad CD/cassette, electromagnetic
interference, etc.). Check the symptoms below to diagnose the malfunction.
 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 oper-
ation of each piece of electrical equipment, and then determine the cause.
NOTE:
 CD-R is not guaranteed to play because they can contain compressed audio (MP3, WMA) or could be incor-
rectly mastered by the customer on a computer.
 Check if the CDs carry the Compact Disc Logo. If not, the disc is not mastered to the red book Compact Disc
Standard and may not play.
Symptom Possible cause Possible solution
No image is displayed.The brightness is at the lowest setting. Adjust the brightness of the display.
The system in the video mode. Push to change the mode.
The display is turned off. Push to turn on the display.
The screen is too dim. The move-
ment is slow.The temperature in the interior of the vehicle is low. Wait until the interior of the vehicle has
warmed up.
Some pixels in the display are dark-
er or brighter than others.This condition is an inherent characteristic of liquid
crystal displays.This is not a malfunction.
Some menu items cannot be se-
lected.Some menu items become unavailable while the ve-
hicle is driven.Park the vehicle in a safe location, and
then operate the multi AV system.
Symptom Cause and Counter measure
Cannot playCheck if the CD was inserted correctly.
Check if the CD is scratched or dirty.
Check if there is condensation inside the player, and if there is, wait until the condensation is gone
(about 1 hour) before using the player.
If there is a temperature increase error, the player will play correctly after it returns to the normal
temperature.
If there is a mixture of music CD files (CD-DA data) and MP3/WMA files on a CD, only the music
CD files (CD-DA data) will be played.
Files with extensions other than “.MP3”, “.WMA”, “.mp3”, or “.wma” cannot be played. In addition,
the character codes and number of characters for folder names and file names should be in com-
pliance with the specifications.
Check if the disc or the file is generated in an irregular format, This may occur depending on the
variation or the setting of MP3/WMA writing applications or other text editing applications.
Check if the finalization process, such as session close and disc close, is done for the disc.
Check if the CD is protected by copyright.
Poor sound quality Check if the CD is scratched or dirty.
It takes a relatively long time before
the music starts playing.If there are many folder or file levels on the MP3/WMA CD, or if it is a multisession disc, some
time may be required before the music starts playing.
Music cuts off or skipsThe writing software and hardware combination might not match, or the writing speed, writing
depth, writing width might not match the specifications. Try using the slowest writing speed.
Skipping with high bit rate files Skipping may occur with large quantities if data such as for high bit rate data.

PRECAUTION
PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000003960542
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:0000000003882788
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 being 7.0 V or less.
 Be sure to turn ignition switch OFF and disconnect the battery cable from the negative terminal before
checking the circuit.
Precaution for Harness RepairINFOID:0000000003882789
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.)

Diagnosis DescriptionINFOID:0000000003765657
MULTIFUNCTION SWITCH AND PRESET SWITCH SELF-DIAGNOSIS FUNCTION
The ON/OFF operation (continuity) of each switch in the multifunction switch and preset switch can be
checked.
Self-diagnosis Mode
 Press the “BACK” switch and the “UP” switch of the 4-direction
switches within 10 seconds after turning the ignition switch from
OFF to ACC and hold them for 3 seconds or more. Then the
buzzer sounds, all indicators of the preset switch illuminate, and
the self-diagnosis mode starts.
 The continuity of each switch at the ON position can be checked
by pressing the switch. The buzzer sounds if the switch is normal.
NOTE:
The hazard switch and disk eject switch cannot be checked.
Finishing Self-diagnosis Mode
Self-diagnosis mode is canceled when turning the ignition switch OFF.
MULTI AV SYSTEM ON BOARD DIAGNOSIS FUNCTION
 The AV control unit diagnosis function starts up with multifunction switch operation and the AV control unit
performs a diagnosis for each unit in the system during the on board diagnosis.
 Perform a CONSULT-III diagnosis if the on board diagnosis does not start, e.g., the screen does not display
anything, the multifunction switch does not function, etc.
ON BOARD DIAGNOSIS
Description
 The trouble diagnosis function has a self-diagnosis mode for conducting trouble diagnosis automatically and
a confirmation/adjustment mode for operating manually.
 Self-diagnosis mode performs the AV control unit diagnosis and the connection diagnosis between each of
the units that make up the system, and it indicates the results to the display.
 The confirmation/adjustment mode allows the technician to check, modify or adjust the vehicle signals and
set values, as well as to monitor the system error records and system communication status. The check,
modify or adjust actions generally require human intervention and judgment (the system cannot make judg-
ment automatically).
