On Board Self-Diagnosis FunctionEKS00BJP
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
NOTE:
Make the status that is set by D/N function be shown.
ModeDescription
Self-diagnosis (DCU) Display control unit diagnosis.
Self-diagnosis (NAVI)

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

Analyzes connection between the NAVI control unit and the GPS
antenna and operation of each unit.
CONFIRMATION/
ADJUSTMENT Display diagnosis
In display control unit mode, color tone and shading of the screen can be
checked by the display of a color bar and a gray scale.
Vehicle signals In display control unit mode, analyzes the following vehicle signals: Vehi-
cle speed signal, light signal
NOTE , ignition switch signal, and reverse sig-
nal.
Auto Climate Control A/C self-diagnosis of A/C system.
Navigation Display diagnosis
In NAVI C/U mode, color tone and shading of the screen can be checked
by the display of a color bar and a gray scale.
Vehicle signals In NAVI C/U mode, analyzes the following vehicle signals: Vehicle speed
signal, light signal, ignition switch signal, and reverse signal.
History of Errors Diagnosis 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.
Naviga-
tion Display Lon-
gitude & Lat-
itude
Display the map. Use the joystick to adjust position. Longitude and latitude
will be displayed.
Speed Cali-
bration Under 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 imme-
diately restores system accuracy in cases such as when distance calibra-
tion is needed because of the use of tire chains in inclement weather.
Angle
adjustment Corrects difference between actual turning angle of a vehicle and turning
angle of the car mark on the display.
Initialize
Location This mode is for initializing the current location. Use when the vehicle is
transported a long distance on a trailer, etc.
CAN DIAG SUPPORT MONITOR Display status of CAN communication.

OPERATION PROCEDURE
1. Start the engine.
2. Turn the audio system off.
3. While pressing the “MEMORY 4” button, turn the volume control
dial clockwise or counterclockwise for 30 clicks or more. (When
the self-diagnosis mode is started, a short beep will be heard.)

Shifting from current screen to previous screen is performed
by pressing “BACK” button.
4. The initial self-diagnosis screen will be shown, and items “Self-
Diagnosis (DCU) ”, “Self-Diagnosis (NAVI) ”, “Confirmation/
Adjustment ” and “CAN DIAG SUPPORT MONITOR ” will
become selective.
5. When “Confirmation/Adjustment ” is selected on the initial self-
diagnosis screen, the operation will enter the CONFIRMATION/
ADJUSTMENT mode. In this mode, check and adjustment of
each item will become possible.
6. The initial trouble diagnosis screen will be shown, and items “Display Diagnosis ”, “Vehicle Signals ”, “Auto Climate Control ”
and “Navigation ” will become selective.
7. Select each switch on “CONFIRMATION/ADJUSTMENT ”
screen to display the relevant diagnosis screen.

VEHICLE SIGNALS

A comparison check can be made of each actual vehicle signal
and the signals recognized by the system.
CAUTION:
In case of confirming light signal, set D/N mode to ON/OFF
of light switch (normal setting).

OFF: D (Day mode)

ON: N (Night mode)
Unless mode is in above setting, light signal (ON/OFF) may
not be accurately displayed.

If vehicle speed is NG, refer to AV- 1 3 1 , "Vehicle Speed Signal Check for NAVI Control Unit" .

If light is NG, refer to AV- 1 3 3 , "Illumination Signal Check for NAVI Control Unit" .

If IGN is NG, refer to AV- 1 3 3 , "Ignition Signal Check for NAVI Control Unit" .

If reverse is NG, refer to AV- 1 3 4 , "Reverse Signal Check for NAVI Control Unit" .
ERROR HISTORY
DIAGNOSIS BY ERROR HISTORY
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.
