Trouble DiagnosisNKS002ED

The majority of the audio malfunctions are the result of outside causes (bad CD, electromagnetic interfer-
ence, etc.). Check the symptoms below to diagnose the malfunction.

The vehicle itself can be a source of noise if noise prevention parts or electrical equipment is malfunction-
ing. Check if noise is caused and/or changed by engine speed, ignition switch turned to each position, and
operation of each piece of electrical equipment, and then determine the cause.

Refer to "SERVICE BULLETIN NTB04-119" for the diagnosis of satellite radio.
NOTE:
Noise resulting from variations in field strength, such as fading noise and multi-path noise, or external noise
from trains and other sources. It is not a malfunction.

Fading noise: This noise occurs because of variations in the field strength in a narrow range due to moun-
tains or buildings blocking the signal.

System DescriptionNKS002EG
With the ignition switch in ACC or ON, power is supplied

through 10A fuse [No. 6, located in the fuse block (J/B)]

to audio unit terminal 10.
Ground is supplied through the case of the antenna amp.
When the radio switch is turned ON, antenna signal is supplied

through audio unit terminal 5

to antenna amp. terminal 1.
Then the antenna amp. is activated.
Antenna signals amplified by the antenna amp. are supplied to the audio unit.

NAVIGATION SYSTEMPFP:25915
System DescriptionNKS000CX
For Navigation System operation information, refer to Navigation System Owner's Manual.
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 DVD-ROM,
which is stored in the DVD-ROM drive (map-matching), and indi-
cated on the screen as a current-location mark. More accurate data is judged and used by comparing vehicle
position detection results found by the GPS with the result by map-matching.
The current vehicle position will be calculated by detecting the dis-
tance the vehicle moved from the previous calculation point and its
direction.

Travel distance
Travel distance calculations are based on the vehicle speed
sensor input signal. Therefore, the calculation may become
incorrect as the tires wear down. To prevent this, an automatic
distance correction function has been adopted.

Travel direction
Change in the travel direction of the vehicle is calculated by a
gyroscope (angular velocity sensor) and a GPS antenna (GPS
information). They have both advantages and disadvantages.
More accurate traveling direction is detected because priorities are set for the signals from these two
devices according to the situation.
SKIB1058E
SEL684V
Type Advantage Disadvantage
Gyroscope (angular velocity sen-
sor)Can detect the vehicle's turning angle quite
accurately.Direction errors may accumulate when vehicle is
driven for long distances without stopping.
GPS antenna (GPS information)Can detect the vehicle's travel direction
(North/South/East/West).Correct direction cannot be detected when vehi-
cle speed is low.

Prior to perform trouble diagnosis, make sure there are no corresponding description in the “Example of
Symptoms Possible No Malfunction”. Refer to AV- 9 5 , "
Example of Symptoms Possible No Malfunction" .
On Board Self-Diagnosis FunctionNKS000D6
DESCRIPTION

Trouble diagnosis function of navigation system has a Self Diagnosis mode by automatic operation and a
Confirmation/Adjustment mode by manual operation.

Self Diagnosis mode checks for connections between the units constituting this system, analyzes each
individual unit at the same time, and displays the results on the display unit.

Confirmation/Adjustment mode displays trouble diagnosis that require an operation and a judgment by a
human (auto-decision can not be performed by the system), confirmation of preset value, and an error his-
tory.
DIAGNOSIS ITEM
Self Diagnosis ModeNKS000D7
OPERATION PROCEDURE
1. Start the engine.
2. Press and hold “MAP” and “ ” buttons simultaneously for 5
seconds or more.

Shifting from current screen to previous screen is performed
by pressing “BACK” button.
Mode Description
Self Diagnosis

NAVI control unit diagnosis (DVD-ROM drive will not be diagnosed when no
DVD-ROM is in it.).

Analyzes connection between the NAVI control unit and the GPS antenna, con-
nection between the NAVI control unit and each unit, and operation of each unit.
Confirmation/
AdjustmentDisplay DiagnosisColor tone and shading of the screen can be checked by the display of a color bar
and a gray scale.
Vehicle SignalsDiagnosis of signals that are input to NAVI control unit can be performed for Vehicle
speed, Lights, Ignition and Reverse.
NavigationSteering Angle
AdjustmentThis mode is used to correct difference between actual turning angle of a vehicle
and turning angle of the vehicle mark on the display.
Speed CalibrationUnder ordinary conditions, the navigation system distance measuring function will
automatically compensate for minute decreases in wheel and tire diameter caused
by tire wear or low-pressure. Speed Calibration can immediately restore system
accuracy in cases such as when distance calibration is needed because of the use
of tire chains.
Error HistoryMalfunctions that occurred in the past are displayed, along with the number of times
each has occurred. Time and location when/where the errors occurred are also dis-
played.
