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 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/".
  1. Using the website's search engine, find out if the customer's phone is on the approved list.
  2. 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.
  3. 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".
  4. If the feature related to the customer's concern shows as "Y" (compatible): Perform diagnosis as per the following table.

NORMAL OPERATING CONDITION

Description

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 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 are 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.

Type of Noise and Possible Cause

Nissan Maxima. Type of Noise and Possible Cause

RELATED TO HANDS-FREE PHONE

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 Compatibility)" in AV-66, "Symptom Table". 

Cannot use hands-free phone. 

Customer will not be able to use a hands-free phone under the following 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 wireless connection, the battery power of the cellular phone may discharge quicker than usual. The Bluetooth Hands-Free Phone System cannot charge cellular phones 

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.
