System FunctionsNKS00489
Here is an example of functions. For details, refer to the owner's manual or navigation system owner's manual.
AUDIO
Speed Sensitive Volume (for BASE System)
Volume level of this system gone up and down automatically in proportion to the vehicle speed. And the
control level can be selected by the customer.
The audio unit inputs the vehicle signal that is sent from unified meter and A/C amp via CAN communica-
tion through AV (NAVI) control unit.
Precision Phased Audio (for BASE System)
It plays back the sound using the woofer (ultra-low bass and clear midrange sound) and reproduces the
sound with presence.
When the conventional BASS/TREBLE adjustment is a maximum, the sounds might be unclear because
the volume of midrange sound also rises together with the bass and treble. The precision phased audio
can emphasize ultra-low bass and ultra-high treble without changing the midrange sound by digital pro-
cessing using DSP.
NOTE:
When the radio is played, the noise may increase more than the presence due to the characteristics of
broadcasting waves. Therefore, the amplification rate while playing the radio is controlled lower than the
rate while playing CD.
AudioPilot® (for BOSE System)
AudioPilot® is the sound improving system that picks up any noises and the sound of music coming into the
vehicle by a microphone under the steering, and that the BOSE amp revises the frequency feature of music at
real time in response to the frequency feature of the noise while driving and listening to music.
If low frequency area noise from vehicle is loud, it adjusts low frequency element of music to be bigger
than vehicle noise.
If high frequency area noise from vehicle is loud, it adjusts all frequency element of music to be bigger
than vehicle noise.
Centerpoint® (for BOSE Surround 5.1ch System)
CD and 2.0ch DVD stereo sound played at audio unit and DVD player are subjected to signal processing in
BOSE amp. It can play the surround sound with presence.
VEHICLE INFORMATION SYSTEM
The status of audio, climate control system, fuel consumption, and navigation system (if equipped) are
displayed.
AV (NAVI) control unit receives the data signal from ECM, unified meter and A/C amp and low tire pres-
sure warning control unit via CAN communication. It calculates the values of fuel economy, tire pressure,
and trip computer from the received information and displays them.
NAVIGATION SYSTEM
Location Detection Principle
The navigation system periodically calculates the vehicle's current
position according to the following three signals:
Travel distance of the vehicle as determined by the vehicle
speed sensor
Turning angle of the vehicle as determined by the gyroscope
(angular velocity sensor)
Direction of vehicle travel as determined by the GPS antenna
(GPS information)
The current position of the vehicle is then identified by comparing the
calculated vehicle position with map data read from the map DVD-
ROM, which is stored in the DVD-ROM drive (map-matching), and

PRECAUTIONS
Revision: 2006 January2006 M35/M45
Precautions for Brake ControlNFS000Q1
Just after starting vehicle after ignition switch ON, brake pedal may vibrate or motor operating noise may
be heard from engine compartment. This is normal condition.
When an error is indicated by ABS or another warning lamp, collect all necessary information from cus-
tomer (what symptoms are present under what conditions) and check for simple causes before starting
diagnostic servicing. Besides electrical system inspection, check brake booster operation, brake fluid
level, and oil leaks.
If tire size and type are used in an improper combination, or brake pads are not Genuine NISSAN parts,
stopping distance or steering stability may deteriorate.
ABS might be out of order or malfunctions by putting a radio (wiring inclusive), an antenna and a lead-in
wire near the control unit.
If aftermarket parts (car stereo, CD player, etc.) have been installed, check for incidents such as harness
pinches, open circuits, and improper wiring.
VDC system may not operate normally or a VDC OFF indicator lamp or SLIP indicator lamp may light.
–When replacing the following parts with parts other than genuine parts or making modifications: Suspen-
sion-related parts (shock absorber, spring, bushing, etc.), tires, wheels (other than specified sizes), brake-
related parts (pad, rotor, caliper, etc.), engine-related parts (muffler, ECM, etc.) and body reinforcement-
related parts (roll bar, tower bar, etc.).
–When driving with worn or deteriorated suspension, tires and brake-related parts.

TROUBLE DIAGNOSIS
Revision: 2006 January2006 M35/M45
Inspection 1: Wheel Sensor CircuitNFS000QL
CAUTION:
Do not check between wheel sensor terminals.
INSPECTION PROCEDURE
1. CHECK SELF-DIAGNOSIS RESULTS
Check the self-diagnosis results.
Is above displayed on the self-diagnosis display?
YES >> GO TO 2.
NO >> INSPECTION END
2. CHECK TIRE
Check air pressure, wear and size.
Are air pressure, wear and size within standard?
YES >> GO TO 3.
NO >>
Adjust air pressure, or replace tire.
Perform the self-diagnosis, and make sure that the result shows “NO DTC IS DETECTED”.
3. CHECK SENSOR AND SENSOR ROTOR
Check sensor rotor for damage.
Check wheel sensor for damage, disconnection or looseness.
OK or NG
OK >> GO TO 4.
NG >>
Repair wheel sensor mount or replace sensor rotor. Then perform the self-diagnosis.
Perform the self-diagnosis, and make sure that the result shows “NO DTC IS DETECTED”.
4. CHECK CONNECTOR
1. Turn ignition switch OFF and disconnect ABS actuator and electric unit (control unit) connector E30 and
malfunctioning wheel sensor connector E41(FR-RH), E59(FR-LH), B101(RR-RH), B102(RR-LH). Check
terminal to see if it is deformed, disconnected, loose, etc., Repair or replace it if any malfunction condition
is found.
2. Reconnect connectors and then perform the self-diagnosis. Refer to BRC-23, "
OPERATION PROCE-
DURE" .
OK or NG
OK >> INSPECTION END
NG >> GO TO 5.

c. While pulling outer socket slowly in 11 . 5 m m (0.453 in) range
from neutral position, make sure rack sliding force is within
specification.
d. If rack sliding force is not within specification, overhaul steering
gear assembly.
CHECKING FRONT WHEEL TURNING ANGLE
Check front wheel turning angle after toe-in inspection. Place
front wheels on turning radius gauges and rear wheels on
stands. Check the maximum inner and outer wheel turning
angles for LH and RH road wheels.
With the engine at idle, turn steering wheel from full left stop to
full right stop and measure the turning angles.
Measure rack stroke if angles are outside the specified value.
Disassemble steering gear assembly to check the cause that
rack stroke is outside of the standard.
Steering angles are not adjustable. Check steering gear assem-
bly, steering column assembly and front suspension compo-
nents for wear or damage if any of the turning angles are
different from the specified value. Replace any of them, if any
non-standard condition exists.
