7. On the diagnosis results screen, each unit name and connection line will be colored according to the diagnosis result, as follows.
NOTE:

Satellite = Satellite radio tuner

DCU = Display control unit

Multifunction switch = A/C and AV switch

If multiple malfunctions occur at the same time for a single
unit, the screen switch colors are determined according to the following order of priority: red > yellow >
gray.
8. Select a switch on the diagnosis results screen, and comments for the diagnosis results will be shown.
SELF-DIAGNOSIS RESULT
Quick Reference Table
1. Select the applicable diagnosis number in the quick reference table of diagnosis result.
2. Confirm the possible malfunction with the diagnosis table, and then perform inspection.
3. Turn ignition switch OFF and perform self-diagnosis again.

When A/C and AV switch has a malfunction, the self-diagnosis cannot be started. Refer to AV- 8 4 , "Unable
to Operate System with A/C and AV Switch" .

When display has a malfunction, the self-diagnosis cannot be started. Refer to AV- 8 6 , "All Images Are Not
Displayed" .
Green : No malfunctioning.

DISPLAY DIAGNOSIS
Color tone and shading of the display control unit-generated image can be checked by the display of a color
bar and a gray scale.

If RGB signal is malfunctioning, the tint of the color bar display is as follows.
VEHICLE SIGNALS
A comparison check can be made of each actual vehicle signal and
the signals recognized by the display control unit.
NOTE:
In case of confirming light signal, set the following D/N mode to ON/
OFF of lighting switch (normal setting).

OFF: D (Day mode)

ON: N (Night mode)
Unless above setting, light signal (ON/OFF) may not be accurately
displayed. R (red) signal error : Light blue (Cyan) tint
G (green) signal error : Purple (Magenta) tint
B (blue) signal error : Yellow tint
