RELATED TO HANDS-FREE PHONE

• Before performing diagnosis, confirm that the cellular phone being used by the customer is compatible with

the vehicle.

• It is possible that a malfunction is occurring due to a version change of the phone even though the phone is

a compatible type. This can be confirmed by changing the cellular phone to another compatible type, and
checking that it operates normally. It is important to determine whether the cause of the malfunction is the
vehicle or the cellular phone.

Check Compatibility

1.

Make sure the customer's Bluetooth

®

 related concern is understood.

2.

Verify the customer's concern.
NOTE:
The customer's phone may be required, depending upon their concern.

3.

Write down the customer's phone brand, model, and service provider.
NOTE:
It is necessary to know the service provider. On occasion, a given phone may be on the approved list with
one provider, but may not be on the approved list with other providers.

4.

Go to “www.nissanusa.com/bluetooth/”.

a.

Using the website's search engine, find out if the customer's phone is on the approved list.

b.

If the customer's phone is NOT on the approved list:
Stop diagnosis here. The customer needs to obtain a Bluetooth

®

 phone that is on the approved list before

any further action.

c.

If the feature related to the customer's concern shows as “N” (not compatible):
Stop diagnosis here. If the customer still wants the feature to function, they will need to get an approved
phone showing the feature as “Y” (compatible) in the “Basic Features” list.

d.

If the feature related to the customer's concern shows as “Y” (compatible):
Perform diagnosis as per the following table.

Description

INFOID:0000000009651966

RELATED TO AUDIO

• The majority of the audio malfunctions are the result of outside causes (bad CD, electromagnetic interfer-

ence, 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 that noise is caused and/or changed by engine speed, ignition switch turned to each position, and
operation of each piece of electrical equipment. 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 that 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.

Noise resulting from variations in field strength, such as fading noise and multi-path noise, or external noise
from trains and other sources, is not a malfunction.
NOTE:
• 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 a time difference between the broadcast waves directly from the

station arriving at the antenna and the waves reflected by mountains or buildings.

RELATED TO TELEPHONE

Symptoms

Cause and Counter measure

Cannot play

Check if the disc or USB device was inserted correctly.

Check that the disc 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.

Files with extensions other than “.MP3 (.mp3)”, “.WMA (.wma)”, “.AAC (.aac)” or “.M4A (.m4a)” 
cannot be played. In addition, the character codes and number of characters for folder names and 
file names should be in compliance 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 compressed audio 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 disc or USB device is protected by copyright.

Poor sound quality

Check if the disc 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 disc or USB device, some time may be required before 
the music starts playing.

Music cuts off or skips

The writing software and hardware combination might not match, or the writing speed, writing 
depth, writing width, etc., might not match the specifications. Try using the slowest writing speed.

Skipping with high bit rate files

Skipping may occur with large quantities of data, such as for high bit rate data.

Move immediately to the next song 
when playing.

If an unsupported compressed audio file has been given a supported extension like “.MP3”, or 
when play is prohibited by copyright protection, the player will skip to the next song.

The songs do not play back in the 
desired order.

The playback order is the order in which the files were written by the writing software, so the files 
might not play in the desired order.

Random/Shuffle may be active on the audio system or on a USB device.

Poor reception only from a certain 
radio broadcast station.

Check incoming radio wave signal strength of applicable broadcast station.

Buzz/rattle sound from speaker

The majority of rattle sounds are not indicative of an issue with the speaker, usually something 
nearby the speaker is causing the rattle.
