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.

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

ILLUMINATION
System Description INFOID:0000000004306640
The control of the illumination lamps operation is dependent upon the position of the lighting switch. When the
lighting switch is placed in the 1ST or 2ND position, the BCM (body control module) receives input signal
requesting the illumination lamps to illuminate. This input signal is communicated to IPDM E/R (intelligent
power distribution module engine room) across CAN communication lines. CPU (central processing unit)
located in the IPDM E/R controls the tail lamp relay coil . This relay, when energized, directs power to the illu-
mination lamps, which then illuminate.
Power is supplied at all times
• to ignition relay, located in IPDM E/R,
• to tail lamp relay, located in IPDM E/R,
• through 15A fuse (No. 52, located in IPDM E/R) and
• through 20A fuse (No. 53, located in IPDM E/R)
• to CPU located in IPDM E/R,
• through 40A fusible link (letter g, located in fuse and fusible link box)
• to BCM terminal 70, and
• through 10A fuse [No. 8, located in fuse block (J/B)]
• to BCM terminal 57.
With the ignition switch in the ON or START position, power is supplied
• to ignition relay, located in IPDM E/R, and
• through 10A fuse [No. 6, located in fuse block (J/B)]
• to BCM terminal 38.
With the ignition switch in the ACC or ON position, power is supplied
• through 10A fuse [No. 20, located in fuse block (J/B)]
• to BCM terminal 11.
Ground is supplied
• to BCM terminal 67
• through grounds M57 and M61, and
• to IPDM E/R terminals 39 and 59
• through grounds E15 and E24.
ILLUMINATION OPERATION BY LIGHTING SWITCH With the lighting switch in the 1ST or 2ND positi on, BCM receives input signal requesting the illumination
lamps to illuminate. This input signal is communicat ed to IPDM E/R across CAN communication lines. CPU
located in the IPDM E/R controls the tail lamp relay coil, which, when energized, directs power
• through 10A fuse (No. 37, located in IPDM E/R)
• through IPDM E/R terminal 29
• to microphone terminal 3 (with Bluetooth)
• to illumination control switch terminal 1
• to glove box lamp terminal 1 (with glovebox lamp)
• to audio unit terminal 9
• to front air control terminal 5
• to A/T device terminal 3 (with 4-speed A/T)
• to CVT device terminal 3 (with CVT)
• to hazard switch terminal 3
• to combination meter terminal 12
• to door mirror remote control switch terminal 16
• to combination switch (spiral cable) terminal 26 (with steering wheel audio control switches)
• to steering wheel audio control switches through combinat ion switch (spiral cable) terminal 18 (with steering
wheel audio control switches).
Ground is supplied
• to microphone terminal 2 (with Bluetooth)
• to glove box lamp terminal 2 (with glove box lamp), and
• to illumination control switch terminal 3
• through grounds M57 and M61.
The illumination control switch controls illuminat ion intensity by varying the ground to the following
• through illumination control switch terminal 2
• to audio unit terminal 8
• to front air control terminal 6
