OPERATION

RELATED TO HANDS-FREE PHONE

Basic Inspection

• Check that the cellular phone is a corresponding type (Bluetooth

™

 correspondence) when the hands-free

related malfunction vehicle is in service before performing a diagnosis.

• There is a case that malfunction occurs due to the version change of the phone type, etc. even though it is a

corresponding type. Therefore, confirm it by changing the cellular phone to another corresponding type
phone, and check that it operates normally. It is necessary to distinguish whether the cause is the vehicle or
cellular phone.

Simple check for Bluetooth

™

 communication

• If cellular phone and AV control unit cannot be connected with Bluetooth

™

 communication, the following pro-

cedure allows the technician to judge which device has a malfunction.

1.

Turn on the cellular phone, not connecting Bluetooth

™

 communication.

2.

Start CONSULT-III, then start Windows

®

.

3.

Set CONSULT-III near the cellular phone.

4.

When operating Bluetooth

™

 registration by cellular phone,

check if CONSULT-III

*

 is displayed on the device name.

(If another Bluetooth

™

 device is located near the cellular phone,

the name of the device will also be displayed.)
NOTE:
*:Displayed device name is “NISSAN-

”.

• If no device name is displayed, cellular phone is malfunctioning.

Repair the cellular phone first, then perform diagnosis. 

• If CONSULT-III is displayed on device name, cellular phone is nor-

mal. Perform diagnosis as per the following table. 

On board self-diagnosis of hands-free phone system

Always perform the on board self-diagnosis at first after completing the basic inspection when the malfunction
is detected on the hands-free phone system. Narrow down possible causes using the Diagnosis Chart if there
is no malfunction in the on board self-diagnosis.
