On Board Self-Diagnosis Function

EKS00G6P

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.

Mode

Description

Self-diagnosis (DCU)

●

Display control unit diagnosis.

●

Perform connection diagnosis and unit diagnosis between display con-
trol unit and each unit.

Self-diagnosis (NAVI)

●

NAVI Control unit diagnosis (DVD-ROM drive) will not be diagnosed
when no map DVD-ROM is in it.

●

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.

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.

Corrects difference between actual turning angle of a vehicle and turning
angle of the car mark on the display.
