The GTN cannot
communicate with its
configuration module.

a valid configuration.

temperatures. The
backlight level will
remain high enough to
be visible in daylight
conditions.
The GTN cooling fan is
powered, but it is not
turning at the desired
RPM.
Crossfill is not
working due to loss
of communication
with other GTN or due
to one GTN needing
service.
Crossfill is configured
"on" but is not working
due to software
mismatch.
