Special Note for Trouble DiagnosisNKS002JP
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.
Delete Unit Connection Log Erase the connection history of unit and error history.

3. The initial trouble diagnosis screen will be shown, and items
“Self Diagnosis” and “Confirmation/Adjustment” will become
selective.
4. Perform self-diagnosis by selecting the “Self Diagnosis”.

Self-diagnosis screen is displayed, and then self-diagnosis
starts.

The bar graph visible below self-diagnosis screen displays
progress of the diagnosis.
5. On the diagnosis results screen, each unit name and connection
line will be colored according to the diagnosis result, as follows.
NOTE:

Control unit = NAVI control unit

Switches = NAVI switch

Only Control unit (NAVI control unit) is displayed in red.

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.
6. Select a switch on the diagnosis results screen, and comments

There is dirt and damage on the
DVD-ROM1. Check if the inserted DVD-ROM is
specified for this navigation system,
and the DVD-ROM is dirty, scratched or
warped.
2. If the results from the above checkup
show no malfunction, insert the same
DVD-ROM, and then restart self-diag-
nosis.
3. If self-diagnosis results still show any
malfunction, replace NAVI control unit.
DVD-ROM not inserted is detected Insert DVD-ROM

is detected1. Check if GPS antenna feeder line is
snapped or pinched.
2. If the results from the above checkup
show no malfunction, replace GPS
antenna, and then restart self-diagno-
sis.
3. If self-diagnosis results still show any
malfunction, replace NAVI control unit.

Steering Angle Adjustment
The steering angle output value detected by the gyroscope can be
adjusted.
Speed Calibration
Usually the automatic distance correction function adjusts the mal-
function in distance caused by the tires wearing down or the tire
pressure change. If prompt adjustment is necessary when the tire
chains are installed etc., perform this procedure.

ERROR HISTORY
Diagnosis results of self-diagnosis depend on if any error occurred during the time after selecting “Self Diag-
nosis” until self-diagnosis results is displayed.
Meanwhile, when an error occurs before selecting “Self Diagnosis”, and if an error does not occur until self-
diagnosis results is displayed, a diagnosis result is judged as normal.
Consequently, a diagnosis needs to be performed with “Error History” for the past error that is not available
with self-diagnosis.
“Error History” displays the time and place of the most recent occurrence of that error. However, take note of
the following points.

Correct time of the error occurrence may not be displayed when the GPS antenna substrate within the
NAVI control unit has malfunctioned.

Place of the error occurrence is represented by the position of the vehicle mark at the time when the error
occurred. If the vehicle mark has deviated from the correct position, then the place of the error occurrence
may not be located correctly.

When the ignition switch is turned ON if the error is detected, the counter increases 1. Even if it is normal
when the ignition switch is turned ON the next time, the counter does not decrease.

The upper limit of the counter is 50. 51 or more is displayed as 50. It can be reset to 0 by “Delete log”
switch.
