On Board Self-Diagnosis Function (Without CONSULT-II)

AKS003XJ

DESCRIPTION 

●

Diagnosis function consists of the self-diagnosis mode performed automatically and the Confirmation/
Adjustment Mode 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 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

●

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

●

Analyzes connection between the AV and NAVI control unit and the GPS 
antenna connection between the AV and NAVI control unit and each unit, 
and operation of each unit.

Confirmation/
Adjustment Mode

Display diagnosis

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, parking brake 
signal, light signal, ignition switch signal, and reverse signal.

Auto Climate Control

Turns all A/C screens on display and A/C switch indicator lamp on.

Navigation

Display Longitude 
& Latitude

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

Speed Calibration

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 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.
