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.

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.
Delete Unit Connection Log Erase the connection history of unit and error history.
