On Board Self-Diagnosis FunctionAKS007IZ
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 (malfunction 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. Mode Description
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 connection between the NAVI control unit and each unit, and
operation of each unit.
Confirmation/
Adjustment Display diagnosis
On 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 On 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
On 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 On 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.
Navigation Display Longi-
tude & Latitude Display the map. Use the joystick to adjust position. Longitude and latitude
will be displayed.
Speed
Calibration 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
immediately restores system accuracy in cases such as when distance
calibration 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 SUPPOPT MONITOR Display status of CAN communication.

Self-Diagnosis Mode (DCU)AKS007J0
OPERATION PROCEDURE
1. Start the engine.
2. Turn the audio system off.
3. While pressing the “MUTE/ II ” 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 “PREV” button.
4. The initial trouble diagnosis screen will be shown, and items “Self-Diagnosis (DCU)”,“Self-Diagnosis (NAVI)”, “Confirmation/
Adjustment” and “CAN DIAG SUPPORT MONITOR” will
become selective.
5. Perform self-diagnosis by selecting the “Self-diagnosis (DCU)”.
Self-diagnosis subdivision screen will be shown and the oper-
ation enters the self-diagnosis mode.
A bar graph shown below the self-diagnosis subdivision
screen indicates progress of the diagnosis.
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.
