- 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 vehicle
or the cellular phone.
Check compatibility
- Make sure the customer’s bluetooth® related concern is understood.
- Verify the customer’s concern.
Note:
The customer’s phone may be required, depending upon their concern.
- 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.
- Go to “www.Nissanusa.Com/bluetooth/”.
- Using the website’s search engine, find out if the customer’s phone is
on the approved list.
- If the customer’s phone is NOT on the approved list: Stop diagnosis here.
The customer needs to obtain a bluetoothВ® phone that is on the approved list
before
any further action.
- 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”.
- If the feature related to the customer’s concern shows as “y” (compatible):
perform diagnosis as per the following table.

Normal operating condition
Description
Related to noise
The majority of the audio concerns are the result of outside causes (bad CD,
electromagnetic interference,
etc.).
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 mountains
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 operation
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.
