Self-Diagnosis FunctionEKS00F32
DESCRIPTION

Diagnosis function consists of the self-diagnosis mode performed automatically and the CONFIRMATION/
ADJUSTMENT mode operated manually.

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 LCD screen.

CONFIRMATION/ADJUSTMENT mode is used to perform trouble diagnosis that require operation and
judgment by an operator (trouble that cannot be automatically judged by the system), to check/change the
set value, and to display the History of Errors of the navigation system.
DIAGNOSIS ITEM
Mode Description
Self-diagnosis

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

Performs diagnosis of each unit and connections between control unit and GPS
antenna, as well as between control unit and each unit.
Confirmation /
AdjustmentDisplayColor tone and shading of the screen can be checked by the display of a color bar
and a gray scale.
Vehicle signalsAnalyzes the following vehicle signals: Vehicle speed signal, light signal, ignition
switch signal, and reverse signal.
History of ErrorsDiagnosis results previously stored in the memory (before turning ignition switch
ON) are displayed in this mode. Time and location when/where the errors occurred
are also displayed.
NavigationDisplay Longitude
& LatitudeDisplay the map. Use the joystick to adjust position. Longitude and latitude will be
displayed.
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 immediately restores system accu-
racy in cases such as when distance calibration is needed because of the use of
tire chains in inclement weather.
Angle AdjustmentCorrects difference between actual turning angle of a vehicle and turning angle of
the car mark on the display.
Initialize LocationThis mode is for initializing the current location. Use when the vehicle is trans-
ported a long distance on a trailer, etc.
Feature Restriction SettingOperations of navigation system that are performed while driving can be restricted
by using this function.

Method of diagnosis for malfunctioning system

When system does not start, indicate malfunction connection between units by outbreak sound from sys-
tem.
Diagnosis procedure
1. Turn ignition switch ON. Make sure whether or not route guide start sound which is output from NAVI con-
trol unit indicate 10 seconds after.
2. Push and hold “MAP” and “ ” switches simultaneously for 5 seconds or more. Make sure whether or not
2 times of beep sound or route guide start sound indicate.
3. According to the former two steps, Select an proper diagnosis No. in the diagnosis result quick reference
table.
4. Find estimated malfunctioning system from the diagnosis No. table and perform check.

3When “DVD-ROM error. Please check disc.” is shown
1. Eject map DVD-ROM and check if it is compatible with the system.
2. Check ejected DVD-ROM for dirt, damage, and warpage.
3. If no error is found, insert a known good map DVD-ROM of the same type and perform self-diagnosis
again. If same result is shown, the NAVI control unit is malfunctioning. If result is normal, the map DVD-
ROM is malfunctioning.–
4If “Error found in DVD-ROM or DVD-ROM driver in control unit. Please perform diagnosis in accordance
with service manual” is shown, carry out same inspection as diagnosis No. 3.–
5GPS antenna system
1. Visually check for a broken wire in the GPS antenna coaxial cable.
2. Disconnect the GPS antenna connector and check that approximately 5V is supplied from NAVI control
unit. If not, the NAVI control unit is inoperative. If the voltage is supplied, replace the GPS antenna and
perform self-diagnosis again. If the same result is shown, the NAVI control unit is inoperative.–

VEHICLE SIGNALS

A comparison check can be made of each actual vehicle signal
and the signals recognized by the system.

If vehicle speed is NG, refer to AV- 8 9 , "Vehicle Speed Signal Check" .

If light is NG, refer to AV- 9 0 , "Illumination Signal Check" .

If IGN is NG, refer to AV- 9 0 , "Ignition Signal Check" .

If reverse is NG, refer to AV- 9 1 , "Reverse Signal Check" .
HISTORY OF ERRORS
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 “History of Error” for the past error that is not available
with self-diagnosis.
“History of Error” 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 be located correctly.

“History of Error” stores error occurrences up to 50, and errors after the 51st are displayed as the 50th.
Diagnosis by History of Errors
When having a difficulty on the investigation of cause due to multiple errors with a reproducible malfunction,
turn ON the ignition switch from OFF mode after making a memo of the item and number of time (or delete
“History of Error”). Check “History of Error” again after the malfunction was reproduced, and then perform
diagnosis focusing on the item of which number of time increased.
