AKS004DW
Refer to
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.

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.

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.
