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
