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.

6. When the self-diagnosis completes, optional part confirmation
screen will be shown.
When connection of an optional part is judged error, a screen
to check if the optional part is actually fitted on the vehicle or
not will be shown. When fitted, select the switch of the part on
the screen and press “End”. Then the “SELF DIAGNOSIS”
screen will be shown.
When the optional part is connected normally, the switch for
the part will not appear on the screen.
7. On the “SELF DIAGNOSIS ” screen, each unit name will be col-
ored according to the diagnosis result, as follows.
If several malfunctions are present in a unit, color of its switch
on the screen will be either red, yellow, or gray, determined by
the malfunction of the highest priority.
8. Select a switch on the “SELF DIAGNOSIS ” screen and com-
ments for the diagnosis results will be shown.
When the switch is green, the following comment will be
shown. “Self-diagnosis was successful. Further diagnosis and
adjustments are recommended. Follow the “confirmation/
adjustment ” menu or refer to the service manual. ”
When the switch is yellow, the following comment will be
shown. “Connection to the following unit is abnormal. See the
service manual for further details ”.
When the switch is red, the following comment will be shown.
“DCU is abnormal”.
SELF–DIAGNOSIS RESULT
Quick reference table
1. Select a malfunctioning diagnosis No. in the diagnosis result quick reference table.
2. Find estimated malfunctioning system in the diagnosis No. table and perform check by referring to AV- 9 7 ,
"Wiring Diagram — COMM —" .
3. Turn the ignition switch OFF and perform self-diagnosis again.
*: DCU = Display control unit
CAUTION:
When AV switch has a malfunction, you cannot start. Refer to AV- 1 5 5 , "Unable to Operate All of AV
Switches (Unable to Start Self-Diagnosis)" .
When display unit has a malfunction, you cannot start. Refer to AV- 1 5 3 , "Screen is Not Shown" .
