tooth cellular telephones may not be recognized by t
he Bluetooth control unit. When a cellular telephone or
the Bluetooth control unit is replaced, the telephone must be paired with the Bluetooth control unit. Different
cellular telephones may have different pairing procedures. Refer to the cellular telephone operating manual.
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 self checks. Initialization may take up to 10 seconds.
During this time the Bluetooth ON indicator will flash until initialization is complete. If a phone is present in the
vehicle and paired with the Bluetooth control unit, NIS SAN Voice Recognition will then become active and the
Bluetooth ON indicator will remain on. Bluetooth te lephone functions can be turned off using the NISSAN
Voice Recognition system. For Bluetooth control unit location, refer to AV-44, " 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
• Record memos
Volume Switch Call volume can be adjusted using the audio unit volume switch.
Bluetooth Microphone The Bluetooth microphone is located in the roof c onsole 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-44, " Component Parts and Harness Connector Location " .
Bluetooth ON Indicator The Bluetooth ON indicator is located in the overhead console. The indicator will flash during power up while
the Bluetooth control unit is initializing. This process may take up to 10 seconds. If a phone is present in the
vehicle and paired with the Bluetooth control unit, the indi cator will remain on to indicate that the system is
ready for voice commands. The indicator flashes duri ng self-diagnosis. For Bluetooth ON indicator location,
refer to AV-44, " Component Parts and Harness Connector Location " .
Audio Unit The audio unit receives signals from the Bluetooth control unit and sends audio signals to the speakers.

Bluetooth Control Unit
Self-Diagnosis Function INFOID:0000000004306987
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 swit ches (SEND/END) stuck closed
• Vehicle speed pulse count
• Bluetooth Microphone connection test (with playback to operator)
• Bluetooth inquiry check

Normal status
• When BCM is not in sleep status, OUTPUT te rminals (1-5) each turn ON-OFF every 10ms.
Sleep status
• When BCM is in sleep mode, transistors of OUTP UT 1 and 5 stop the output, and BCM enters low-cur-
rent-consumption mode. OUTPUTS (2, 3, and 4) turn ON-OFF at 60ms intervals, and receives lighting
switch input only.
CAN COMMUNICATION CONTROL CAN communication allows a high rate of information through the two communication lines (CAN-L, CAN-H)
connecting the various control units in the system. Each control unit transmits/receives data, but selectively
reads required data only.
BCM STATUS CONTROL BCM changes its status depending on the operation stat us in order to save power consumption.
1. CAN communication status • With ignition switch ON, CAN communicates with other control units normally.
• Control by BCM is being operated properly.
• When ignition switch is OFF, switching to sleep mode is possible.
• Even when ignition switch is OFF, if CAN co mmunication with IPDM E/R and combination meter is
active, CAN communication status is active.
2. Sleep transient status • This status shuts down CAN communication when ignition switch is turned OFF.
• It transmits sleep request signal to IPDM E/R and combination meter.
• Two seconds after CAN communication of all control units stops, CAN communication switches to inac-
tive status.
3. CAN communication inactive status • With ignition switch OFF, CAN communication is not active.
• With ignition switch OFF, control performed only by BCM is active.
• Three seconds after CAN communication of all cont rol units stops, CAN communication switches to
inactive status.
4. Sleep status • BCM is activated with low current consumption mode.
• CAN communication is not active.
