There are actually two plugs under there! They are diagnostic plugs used to
place the GTS1000 in service or diagnostic modes. We use them most often to
exercise and test the ABS HU. A quick look under the GTS1000 archives will
reveal that procedure. Search on "rachet". Awe heck....here it is.
Certainly the easiest way to test
the ABS is to simply stomp on the
rear
brake and see if it locks up.
Make sure you're on a flat road
and have the
bike at around 20 MPH. That way
you can easily control the bike
if the rear
does lock up. For some reason,
the rear ABS seems to fail more
often than
the front. Thats right, you can
have the rear ABS fail, but the
front can
work just fine. That's because
the ABS pump has two independent
selonoid
chambers that operate the front
and back. The pump provides
pressure for
both.
The best way to statically test
the ABS HU is to run the HU
diagnostics.
1. Remove the seat and find the
diagnostic plug hidden above
where the tool
pouch is, secured in the tail of
the bike. There are two
diagnostic plugs,
get the one just above the tool
pouch.
2. There is a locking tab
securing the protective insert.
Lift the locking
tab up with your finger and
gently pull the dummy plug out
with a pair of
pliers.
3. You want to short out the two
conductors adjacent(closest) to
the
locking
tab.
4. Pull in the front brake lever
firmly and push down on the rear
brake.
5. While holding both brakes,
turn the ignition key to the ON
position.
6. You will first feel the front
brake lever push(kind of a
ratchet sound)
out against your grip, then fall
back to where it was. Next the
rear brake
pedal will ratchet up against
your foot then fall back to where
it was. The
important part is the initial
ratcheting push out against your
foot or hand
pressure. Even if you hold the
levers firmly, the HU pump should
be able to
push out against you! Don't grip
the lever with all your might or
stand
with
your full body weight on the rear
lever, but DO apply firm braking
pressure.
Any questions?

There is a plug under the real cowling that goes nowhere. What is if for? I
can not find a mention of it in the book. If it's an accessory plug, then I
have a use for it.
