On Board Self-Diagnosis Function

AKS004RD

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 (incident 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

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 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 NAVI control unit 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.

Naviga-
tion

Display Lon-
gitude & Lat-
itude

Display the map. Use the joystick to adjust position. Longitude and latitude
will be displayed.

Speed Cali-
bration

Under 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
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.
