Bluetooth Telephone System Diagram
Bluetooth Control Unit
When the ignition switch is turned to ACC or ON, the Bluetooth control unit will power up. During power up, the
Bluetooth control unit is initialized and performs various se lf checks. Initialization may take up to 20 seconds. If
a phone is present in the vehicle and paired with the Bl uetooth control unit, Nissan Voice Recognition will then
become active. Bluetooth telephone func tions can be turned off using the Nissan Voice Recognition system.
For Bluetooth control unit location, refer to AV-76, "
Component Parts and Harness Connector Location".
Steering Wheel Audio Control Switches
When buttons on the steering wheel audio control switch are pushed, the resistance in steering wheel audio
control switch circuit changes depending on which button is pushed. The Bluetooth control module uses this
signal to perform various functions while navigating through the voice recognition system.
The following functions can be performed usi ng the steering wheel audio control switch:
• Initiate Self Diagnosis of the Bluetooth telephone system
• Start a voice recognition session
• Answer and end telephone calls
• Adjust the volume of calls
Volume Switch
Call volume can be adjusted using the AV control unit volume switch.
Bluetooth Microphone
The Bluetooth microphone is located in the roof console assembly. The Bluetooth microphone sends a signal
to the Bluetooth control unit. The Bluetooth microphone can be actively tested during self-diagnosis. For Blue-
tooth microphone location, refer to AV-76, "
Component Parts and Harness Connector Location".
AV Control Unit
The AV control unit receives signals from the Bluetoot h control unit and sends audio signals to the speakers.

Bluetooth Control Unit Self-Diagnosis FunctionINFOID:0000000005924430
The Bluetooth control unit has two diagnostic checks. The first 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
• Bluetooth Microphone connection test (with playback to operator)
• Bluetooth inquiry check
SELF-DIAGNOSIS MODE
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.
NOTE:
At any time, press and hold the steering wheel audio control
switch PHONE/SEND button for at least 5 seconds to exit diag-
nostic mode.
4. While the prompt is playing, press and hold the steering wheel audio control switch PHONE/END button for at least 5 seconds.
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 for at least 5 seconds
again.
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-82, "
Workflow".
7. If there are no failure records to report, the speed pulse count
will be reported next.
8. After the speed pulse count is reported, an interactive Bluetooth microphone test will be performed. Follow the voice pr ompt. If the Bluetooth microphone test fails refer to
AV-82, "
Workflow".
9. Self-diagnosis mode is complete when the voice prompt says "All diagnostic functions completed". A short beep is heard.
