DISPLAY DIAGNOSIS

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-137, "Color of RGB Image is Not Proper (All
Screen Looks Bluish)" , AV-138, "Color of RGB Image is Not Proper (All Screen Looks Reddish)" and
AV- 1 3 9 , "
Color of RGB Image is Not Proper (All Screen 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.

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 light switch (normal setting).

OFF: D (Day mode)

ON: N (Night mode)
Unless mode is in above setting, light signal (ON/OFF) may
not be accurately displayed.

If vehicle speed is NG, refer to AV- 1 2 1 , "Vehicle Speed Signal Check for NAVI Control Unit" .

If light is NG, refer to AV- 1 2 3 , "Illumination Signal Check for NAVI Control Unit" .

If IGN is NG, refer to AV-123, "Ignition Signal Check for NAVI Control Unit" .

If reverse is NG, refer to AV-124, "Reverse Signal Check for NAVI Control Unit" .
