When RGB signal error occurred in the RGB system, tone of the color bar will change as follows.
When the color of the screen looks unusual, refer to AV- 1 6 2 , "Color of RGB Image is Not Proper (All
screens Looks Bluish)" ,AV- 1 6 3 , "Color of RGB Image is Not Proper (All Screens Looks Reddish)" and
AV- 1 6 4 , "
Color of RGB Image is Not Proper (All Screens Looks Yellowish)" .
VEHICLE SIGNALS
A comparison check can be made of each actual vehicle signal
and the signals recognized by the system.
CAUTION:
In case of confirming light signal, set 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.
If vehicle speed is NG, refer to AV- 1 5 0 , "Vehicle Speed Signal Check for Display Control Unit" .
If light is NG, refer to AV- 1 5 2 , "Illumination Signal Check for Display Control Unit" .
If IGN is NG, refer to AV- 1 5 2 , "Ignition Signal Check for Display Control Unit" .
If reverse is NG, refer to AV- 1 5 3 , "Reverse Signal Check for Display Control Unit" .
AUTO CLIMATE CONTROL
Refer to ATC Automatic Air Conditioner AT C - 5 3 , "Self-diagnosis Function" for details. R (red) signal error : Screen looks bluish
