DIAGNOSIS ITEM

Self-Diagnosis Mode

AKS004DU

Refer to 

AV-69, "Self-Diagnosis Mode"

 .

Confirmation/Adjustment Mode

AKS004DV

Refer to 

AV-73, "Confirmation/Adjustment Mode"

 .

CONSULT-ll Function

AKS004DW

Refer to 

AV-79, "CONSULT-II Function"

 .

Multifunction Switch Self-Diagnosis Function

AKS004DX

It can check ON/OFF operation of each switch in the multifunction switch and diagnose the input signals to the
rear control switch (audio) and steering switch (audio).

STARTING THE SELF-DIAGNOSIS MODE

1.

Turn ignition switch from OFF to ACC.

2.

 Within 10 seconds press and hold the function switches “1” and
“6” simultaneously for 5 seconds.

Then the self-diagnosis operates.

Mode

Description

Self-diagnosis

AV and NAVI Control unit diagnosis (DVD-ROM drive will not be diag-
nosed 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

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.

Speaker Test

Checks the connection of each speaker using a test tone.

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 func-
tion 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.

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.

Rear View Camera

Changes position of the aiming line overlapped on the rear view image.

TION SYSTEM

EXITING THE SELF-DIAGNOSIS MODE

Turn ignition switch OFF, or press and hold the function switches “1” and “6” simultaneously for 5 seconds.
Then the self-diagnosis ends.

DIAGNOSIS FUNCTION 

It can illuminate all the indicators (LED) in the multifunction switch.

It can check for continuity of the switches by sounding the buzzer when the multifunction switch is
pressed.

It can check for continuity of harness between multifunction switch and rear control switch (audio), or
steering switch (audio).

NOTE:
When it check continuity of harness between multifunction switch and rear control switch (audio), rear
control cancel switch is OFF position.
