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.

DISPLAY DIAGNOSIS

When RGB signal error occurred in the RGB system, tone of the color bar will change as follows.

When the color of the screen looks unusual, refer to AV- 1 6 0 , "Color of RGB Image Is Not Proper (All
Screens Looks Bluish)" , AV- 1 6 1 , "Color of RGB ImageIs Not Proper (All Screens Looks Reddish)" and
AV- 1 6 2 , "
Color of RGB Image Is Not Proper (All Screens Looks Yellowish)" .
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 lighting switch (normal setting).

OFF: D (Day mode)

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