Self-Diagnosis Function
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
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.
Con®rmation/
Adjustment Display
Color tone and shading of the screen can be checked by the display of a color
bar and a gray scale.
Vehicle signals Analyzes the following vehicle signals: Vehicle speed signal, light signal, ignition
switch signal, and reverse signal.
Navigation Display Longi-
tude & Lati-
tude
Display the map. Use the joystick to adjust position. Longitude and latitude will be
displayed.
Speed Calibra-
tion 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 sys-
tem accuracy in cases such as when distance calibration is needed because of
the use of tire chains in inclement weather.
Angle Adjust-
ment Corrects difference between actual turning angle of a vehicle and turning angle of
the car mark on the display.
Initialize Loca-
tion This mode is for initializing the current location. Use when the vehicle is trans-
ported a long distance on a trailer, etc.
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.
Self-Diagnosis Mode
OPERATION PROCEDURE
1. Start the engine.
2. Push and hold ªMAPº and ªDAY/NIGHTº switches simulta-
neously for 5 seconds or more.
+ Push the ªBACKº switch and the initial system screen will
be shown.

1 NAVI control unit malfunction Ð
2 NAVI control unit judged no map DVD-ROM is inserted. Ð
3 When ªDVD-ROM is not recognized. Please check the disc.º 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 warps.
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. Ð
4 If ªError found in DVD-ROM or DVD-ROM driver in control unit. Please perform diagnosis in
accordance with service manualº is shown, performed same inspection as diagnosis No. 3. Ð
5 GPS antenna system
1. Visually check for a broken wire in the GPS antenna coaxial cable.
2. Disconnect the GPS antenna connector and make sure 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. Ð
