outputs to the four speaker lines one
after the other for 1 second.
The frequency can be chosen by user
selection (100Hz and 4KHz).

Display test —This provides a test sequence where
test displays (plain colored display:
e.g. white, black, red, blue, green) are
shown one after the other.
The respective color is shown for an
indicated period of time (parameter).
After the display test, the design of the
display previously available is stored.
While the screen shows a plain col-
ored display, a pixel malfunction may

END ON-BOARD DIAGNOSIS
Turn OFF ignition switch.
Noise InspectionINFOID:0000000005931317
The vehicle itself can be a source of noise if noise
prevention parts or electrical equipment is malfunctioning.
Check if noise is caused and/or changed by engine speed, ignition switch turned to each position, and opera-
tion of each piece of electrical equipment, and determine the cause.
NOTE:
The source of the noise can be found easily by listening to the noise while removing the fuses of electrical
components, one by one.

Occurrence condition Possible cause
Occurs only when engine is ON. A continuous growling noise occurs. The speed of
the noise varies with changes in the engine speed.
Ignition components
A whistling noise occurs while the engine speed is
high. A booming noise occurs while the engine is
running and the lighting switch is ON. Generator
Noise only occurs when various
electrical components are oper-
ating. A cracking or snapping sound occurs with the op-
eration of various switches.
Relay malfunction, radio malfunction
The noise occurs when various motors are operat-
ing. • Motor case ground
• Motor
The noise occurs constantly, not just under certain conditions. • Rear defogger coil malfunction
• Open circuit in printed heater
A cracking or snapping sound occurs while the vehicle is being driven, especially when
it is vibrating excessively. • Ground wire of body parts.
• Ground due to improper part installation
• Wiring connections or a short circuit

MALFUNCTION WITH AUDIO
• The majority of the audio malfunctions are the result of outside causes (Malfunction CD, electromagnetic interference, etc.). Check the sympt oms below to diagnose the malfunction.
• The vehicle itself can be a source of noise if noise prevention parts or electrical equipment is malfunctioning.
Check if noise is caused and/or changed by engine speed, ignition switch turned to each position, and oper-
ation of each piece of electrical equipment, and then determine the cause.
NOTE:
• CD-R is not guaranteed to play because they can contain compressed audio (MP3, WMA) or could be incorrectly mastered by the customer on a computer.
• Check if the CDs have the Compact Disc logo. If not, the disc is not mastered to the “red book” Compact
Disc standard and may not play.

TELEPHONE
When a cellular telephone or the Bluetooth control uni
t 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 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 functions can be tur ned off using the Nissan Voice Recognition system.
For Bluetooth control unit location, refer to AV-77, "
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 using 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 c an be actively tested during self-diagnosis. For Blue-
tooth microphone location, refer to AV-77, "
Component Parts and Harness Connector Location".
AV Control Unit
The AV control unit receives signals from the Bluet ooth control unit and sends audio signals to the speakers.
