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

check that it operates normally. It is important to determine whether the cause of the malfunction is the vehi-

cle or the cellular phone.

Noise is mixed with audio.

Noise comes out from all speakers.

• Malfunction in AV control unit.

Refer to

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”.

d. If the feature related to the customer’s concern shows as “Y” (compatible):

Perform diagnosis as per the following table.

NORMAL OPERATING CONDITION

Description

INFOID:0000000010064923

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

RELATED TO HANDS-FREE PHONE

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

Symptom

Cause and Counter measure

Does not recognize cellular phone connection (No connection is 
displayed on the display at the guide).

Some Bluetooth

®

 enabled cellular phones may not be recognized 

by the in-vehicle phone module.
Refer to “RELATED TO HANDS-FREE PHONE (Check Compati-
bility)” in 

AV-304, "Symptom Table"

.

Cannot use hands-free phone.

Customer will not be able to use a hands-free phone under the fol-
lowing conditions:
• The vehicle is outside of the telephone service area.
• The vehicle is in an area where it is difficult to receive radio 

waves; such as in a tunnel, in an underground parking garage, 
near a tall building or in a mountainous area.

• The cellular phone is locked to prevent it from being dialed.
NOTE:
While a cellular phone is connected through the Bluetooth

®

 wire-

less connection, the battery power of the cellular phone may dis-
charge quicker than usual. The Bluetooth

®

 Hands-Free Phone 

System cannot charge cellular phones.
