D
rivers, is the CTIS light on the dash of your LTAS FMTV lit? Is it driving you batty?
Then you need to eyeball the CTIS switch bypass cable (plug 31). It’s inside the cab
under the instrument panel. This cable should be unplugged
only
when the vehicle is
operating in cold temperatures and has an arctic heater kit installed.
Most of these LTAS vehicles
were fielded without the arctic
heater
but
with
the
cable
unplugged. That means the CTIS
is off.
It’s not a big deal as long as
you’re willing to manually check
the tire pressure for whatever
terrain
and
speed
you’re
operating at. But it does mean
that CTIS light is gonna glow!
So just plug the cable back
in place to power up the CTIS
system and out goes the light!
Bypass cable
unplugged? CTIS
light will be on
FMTV…
Blinded by the
CTIS Light?
