7. On the diagnosis results screen, each unit name and connection
line will be colored according to the diagnosis result, as follows.
NOTE:

Satellite = Satellite radio tuner

DCU = Display control unit

Multifunction switch = A/C and AV switch

If multiple malfunctions occur at the same time for a single
unit, the screen switch colors are determined according to the following order of priority: red > yellow >
gray.
8. Select a switch on the diagnosis results screen, and comments for the diagnosis results will be shown.
SELF-DIAGNOSIS RESULT
Quick Reference Table
1. Select the applicable diagnosis number in the quick reference table of diagnosis result.
2. Confirm the possible malfunction with the diagnosis table, and then perform inspection.
3. Turn ignition switch OFF and perform self-diagnosis again.

When A/C and AV switch has a malfunction, the self-diagnosis cannot be started. Refer to AV- 8 4 , "Unable
to Operate System with A/C and AV Switch" .

When display has a malfunction, the self-diagnosis cannot be started. Refer to AV- 8 6 , "All Images Are Not
Displayed" .
Green : No malfunctioning.
Gray : Cannot be judged by self-diagnosis results.
Red : Unit is malfunctioning.

Self-Diagnosis Codes
Diagnosis
No. Possible cause Action to take
1 Display control unit malfunction is detected. Replace display control unit.
2 Malfunction is detected on communication signal between
display control unit and display. 1. Check communication circuit between display control
unit and display.
2. Check communication signal between display control unit and display.
3. If the results from the above checkup show no malfunc- tion, replace either display control unit or display, and
then start self-diagnosis.
4. If self-diagnosis results still show any malfunction, replace the other unit.
3

Audio unit power supply circuit malfunction is detected.

Malfunction is detected on communication signal
between display control unit and audio unit. 1. Check audio unit power supply circuit.
2. Check communication circuit between display control unit and audio unit.
3. Check communication signal between display control unit and audio unit.
4. If the results from the above checkup show no malfunc- tion, replace either display control unit or audio unit, and
then start self-diagnosis.
5. If self-diagnosis results still show any malfunction, replace the other unit.

NAVIGATION SYSTEM
Revision: 2006 July 2007 FX35/FX45
GPS (Global Positioning System)
GPS (Global Positioning System) was developed for and is con-
trolled by the US Department of Defense. The system utilizes GPS
satellites (NAVSTAR), sending out radio waves while flying on an
orbit around the earth at an altitude of approximately 21,000 km
(13,100 miles).
The GPS receiver calculates the vehicle's position in three dimen-
sions (latitude/longitude/altitude) according to the time lag of the
radio waves received from four or more GPS satellites (three-dimen-
sional positioning). If radio waves were received only from three
GPS satellites, the GPS receiver calculates the vehicle's position in
two dimensions (latitude/longitude), and utilize the altitude data cal-
culated previously with radio waves from four or more GPS satellites
(two-dimensional positioning).
Position correction by GPS is not available while the vehicle is stopped.
Accuracy of GPS will deteriorate under the following conditions:

In two-dimensional positioning, GPS accuracy will deteriorate when altitude of the vehicle position
changes.

The accuracy can be even lower depending on the arrangement of the GPS satellites utilized for the posi-
tioning.

Position detection is not possible when vehicle is in an area where radio waves from the GPS satellite do
not reach, such as in a tunnel, parking lot in a building, and under an elevated highway. Radio waves from
the GPS satellites may not be received when some object is located over the GPS antenna.
NOTE:

Even a high-precision three dimensional positioning, the detection result has an error about 10 m (30ft).

Because the signals of GPS satellite is controlled by the Tracking and Control Center in the United States,
the accuracy may be degraded lower intentionally or the radio waves may stop.

Component DescriptionNKS003K1
NAVI CONTROL UNIT

The gyro (angular speed sensor) and the DVD-ROM drive are
built-in units that control the navigation functions.

Signals are received from the gyro, the vehicle speed sensor,
and the GPS antenna. Vehicle location is determined by com-
bining this data with the data contained in the DVD-ROM map.
Locational information is shown on liquid crystal display panel.
DVD-ROM Drive
Maps, traffic control regulations, and other pertinent information can
be easily read from the DVD-ROM.
DVD-ROM

The DVD-ROM has maps, traffic control regulations, and other pertinent information.

To improve DVD-ROM map matching and route determination functions, the DVD-ROM uses an exclusive
Nissan format. Therefore, the use of a DVD-ROM provided by other manufacturers cannot be used.
Gyro (Angular Speed Sensor)

The oscillator gyro sensor is used to detect changes in vehicle steering angle.

The gyro is built into the navigation (NAVI) control unit.
GPS ANTENNA
The GPS antenna receives and amplifies the radio waves from the GPS satellites, and then transmits the GPS
signal to NAVI control unit.
DISPLAY CONTROL UNIT

Display control unit draws a status of the audio and air condi-
tioner, a TRIP screen, a FUEL ECONOMY screen, etc., and
transmits the image signals to the display screen.

It receives operation signals of audio and air conditioner from A/
C and AV switch, and transmits the operation signal of audio to
the audio unit via the communication line and transmits the
operation signal of air conditioner to the meter and A/C amp. via
CAN communication.
