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 indi-
vidual 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 judg-
ment 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.
Self-Diagnosis Mode (DCU)INFOID:0000000003533719
OPERATION PROCEDURE
1. Start the engine.
2. Turn the audio system off.
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 anten-
na and operation of each unit.
CONFIRMATION/
ADJUSTMENTDisplay diagnosisIn 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 signalsIn display control unit mode, analyzes the following vehicle signals: Vehicle
speed signal, light signal
NOTE, ignition switch signal, and reverse signal.
Auto Climate Control A/C self-diagnosis of A/C system.
NavigationDisplay diagnosisIn 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 signalsIn NAVI C/U mode, analyzes the following vehicle signals: Vehicle speed
signal, light signal, ignition switch signal, and reverse signal.
History of ErrorsDiagnosis 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-
tionDisplay Lon-
gitude & Lat-
itudeDisplay the map. Use the joystick to adjust position. Longitude and latitude
will be displayed.
Speed Cali-
brationUnder ordinary conditions, the navigation system distance measuring func-
tion will automatically compensate for minute decreases in wheel and tire
diameter caused by tire wear or low-pressure. Speed calibration immedi-
ately restores system accuracy in cases such as when distance calibration
is needed because of the use of tire chains in inclement weather.
Angle ad-
justmentCorrects difference between actual turning angle of a vehicle and turning
angle of the car mark on the display.
Initialize Lo-
cationThis 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.
