DIAGNOSIS SYSTEM (BLU ETOOTH® CONTROL UNIT)
Diagnosis DescriptionINFOID:0000000012432873
The Bluetooth® control unit has two diagnostic checks. The fi rst diagnostic check is performed automatically
every ignition cycle during control unit initialization. The second diagnostic check is performed by the techni-
cian using the steering wheel audio control switches prior to trouble diagnosis.
BLUETOOTH® CONTROL UNIT INITIALIZATION CHECKS
• Internal control unit failure
• Bluetooth
® antenna connection open or shorted
• Steering wheel audio control switches [ (PHONE/SEND), (PHONE/END)] stuck closed
• Vehicle speed pulse count
• Microphone connection test (with playback to operator)
• Bluetooth
® inquiry check
OPERATION PROCEDURE
1. Turn ignition switch to ACC or ON.
2. Wait for the Bluetooth
® system to complete initialization. This may take up to 20 seconds.
3. Press and hold the steering wheel audio control switch (PHONE/SEND) button for at least 5 seconds. The Bluetooth
®
system will begin to play a verbal prompt.
4. While the prompt is playing, press and hold the steering wheel audio control switch (PHONE/END) button until you hear the
“Diagnostics mode” prompt. The Bluetooth
® system will sound a
5-second beep.
5. While the beep is sounding, press and hold the steering wheel
audio control switch (PHONE/END) button again until you
hear prompts.
6. The Bluetooth
® system has now entered into the diagnostic
mode. Results of the diagnostic checks will be verbalized to the
technician. Refer to AV-17, "
Work Flow".
7. After the failure records are reported, an interactive microphone test will be performed. Follow the voice prompt. If the micro-
phone test fails, refer to AV-17, "
Work Flow".

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 thoug\
h 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 c ause of the malfunction is the vehi-
cle 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”.
d. If the feature related to the customer ’s concern shows as “Y” (compatible):
Perform diagnosis as per the following table.
No radio reception or poor reception. • Other audio sounds are normal.
• Any radio station cannot be received or
poor reception is caused even after mov-
ing to a service area with good reception
(e.g. a place with clear view and no ob-
stacles generating external noises). • Antenna amp. ON signal circuit malfunc-
tion.
Refer to AV- 1 8 , "Reference Value".
• Poor connector connection of antenna or antenna feeder.
Refer to AV- 6 1 , "
Feeder Layout".
Buzz/rattle sound from speaker The majority of buzz/rattle sounds are not
indicative of an issue with the speaker, usu-
ally something nearby the speaker is caus-
ing the buzz/rattle.Refer to "SQUEAK AND RATTLE TROU-
BLE DIAGNOSIS" in the appropriate interi-
or trim section.
Symptoms

Symptoms Check itemsProbable malfunction location
Does not recognize cellular phone connec-
tion (no connection is displayed on the dis-
play at the guide). Repeat the registration of cellular phone.
Malfunction in audio unit.
Refer to AV- 1 4 , "
On Board Diagnosis Func-
tion".
Hands-free phone cannot be established. • Hands-free phone operation can be
made, but the communication cannot be
established.
• Hands-free phone operation can be per- formed, however, voice between each
other cannot be heard during the conver-
sation.
The other party’s voice cannot be heard by
hands-free phone. Check the “microphone speaker” in Inspec-
tion & Adjustment Mode if sound is heard.
Originating sound is not heard by the other
party with hands-free phone communica-
tion. Sound operation function is normal.
Sound operation function does not work.
Microphone signal circuit malfunction.
Refer to AV- 4 4 , "

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 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, 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
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- 4 8 , "
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.

NORMAL OPERATING CONDITION
The other party’s voice cannot be heard by hands-free phone.When the radio wave condition is not ideal or ambient sound is too
loud, it may be difficult to hear the other person’s voice during a
call.
Poor sound quality. Do not place the cellular phone in an area surrounded by metal or
far away from the in-vehicle phone module to prevent tone quality
degradation and wireless connection disruption.
