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, igni-
tion switch signal, and reverse signal.
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 accuracy 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.
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.

1 NAVI control unit malfunction–
2 NAVI control unit judged no map DVD-ROM is inserted. –
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.–

DIAGNOSIS BY HISTORY OF ERRORS
The “Self-diagnosis” results indicate whether an error occurred during the period from when the ignition switch
is turned to ON until “Self-diagnosis” is completed.
If an error occurred before the ignition switch was turned to ON and does not occur again until the “Self-diag-
nosis” is completed, the diagnosis result will be judged normal. Therefore, those errors in the past, which can-
not be found by the “Self-diagnosis”, must be found by diagnosing the “History of Errors”.
The History of Errors 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 current-location mark at the time when
the error occurred. If the current-location mark has deviated from the correct position, then the place of
the error occurrence may be located correctly.
The maximum number of occurrences which can be stored is 50. For the 51st and later occurrences, the
displayed number remains 50.
When a reproducible malfunction occurred but its cause cannot be identified because several errors are
present, record the item, number and place (longitude/latitude) of error occurrence (or delete the History of
Errors), then turn the ignition switch from OFF to ON to reproduce the malfunction. Check the History of Errors
to find the items which show an increased number of occurrences, and diagnose the item.
