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 (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.

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.

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 
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 SUPPORT MONITOR

Display status of CAN communication.
