RELATED TO HANDS-FREE PHONE

Basic Inspection

Check that the cellular phone is corresponding type (Bluetooth™ correspond) 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, following procedure allows the technician to judge which device has malfunction.
1. Turn on a cellular phone, not connecting Bluetooth™ communication.
2. Start CONSULT-III, then start Windows®.
3. Set CONSULT-III near a cellular phone.
4. When operated Bluetooth™ registration by cellular phone, check if CONSULT-III* would be displayed on the device name.
  (If other Bluetooth™ device is located near cellular phone, a name of the device would be displayed also.)
  
  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 normal. Perform diagnosis as per the following table.
