hello i have a 05 GMC sierra and the abs computer wont connect with
computer. I have a
ABS brakes scanner but it say check connections.
i have a 2002
Buick Rendezvous and my ABS brake light has started to
come on and my AWD has shut itself off for some reason. It has 107000
miles and other than this it is in excellent shape. Any ideas
You probably have a wheel speed sensor that is bad
on one or more hubs. You'd have to get the code
pulled to see which one exactly. Also check the wiring
harnesses to the sensors for corrosion. For the
AWD, could be a mechanical failure, or electronic,
that would need to be checked out by a tech.
Check to see if the you can pull codes from the
engine computer. If not, i would suspect just a blown
fuse for the diagnostic connector. If you can, then
you could have a bad ABS module. Test your
scanner on another similar vehicle first.
AWD disabled light comes on when I put my foot on the brake to start the
car in the morning. Not getting the ABS light. Light went off both times after
driving 4-5 miles. No glitches showed up in a computer check yesterday.
The light never came back on when the car was used 3-4 times during the
day. Only during morning start.
my abs lights up every time i turn on my head/ taillights. What can be the
cause? If i keep them turned off, the abs dont light up.
HMMM. That is a strange one. If the light does not
come on when foot not on the brake, I would guess
you have a short somewhere. AWD can be disabled
without ABS problems. There may be a problem in
the rear differential. That is a different module. This
one needs a dealer to look at.
You may have a low voltage condition on your
vehicle. Low system voltage will set an ABS code
since it cannot operate properly. Headlights and park
lights use quite a bit a system voltage.
My 2004 Honda accord has around 70 K and today my check
engine/emissions light, abs light and brake light all came on at once. What's
wrong with my car or is something wrong with my sensors?
I had an RTA a couple of weeks ago - i was stationery waiting behind a
vehicle for the oncoming traffic and another vehicle smashed into the rear
of me. The impact forced my CD out of its casing and now doesn't work and
also the ABS light is continually on.  The vehicle rear end has been
repaired but they state the ABS light and internal CD/Casing is not related
to the RTA - IS THIS TRUE??? As after my car was smashed into the
vehicle disabled itself and also the CD is hanging out with all the wires
showing - PLEASE HELP ???
I bought a 2006
Chevy Uplander about 3 weeks ago. The brakes were
serviced when I bought it. I've put about 1500 kms on since buying it. Just
now the ABS light, traction light, and stability warning all came on. Could
this all be connected with having the brakes done??
Usually, doing the brakes does not cause the ABS
system light to come on or have problems. There are
times, however, that the wiring and/or hub bearing
with integral wheel speed sensor can be disturbed
doing this if someone was hammering or otherwise
being rough in that general area. If the rotors were
rusted on pretty good, they can need some heavy
beating on to remove fully. That could be a cause.
You'd need to get the code pulled to see exactly
which wheel is acting up, but it sounds like you are
going to need at least one new hub bearing
assembly. When they go bad, the lights you mention
will come on and there may be an abnormal feeling in
the brakes when coming to a stop.
2002 Suburban 4wd. ABS light on but no codes? When you turn key on
ABS light goes on-off for a moment-and on again. Checked with a Genesis
scanner with 2004 ABS installed/unlocked, so a cheap scanner is not the
issue. Any idea of possible causes?
Personally, I wouldn't rely on the scanner results. You
should really get it scanned at a dealer or by
someone who has a Tech2. If the light is on, there is
definitely a code set somewhere in the system. If
you've got Stabililtrak, or Traction Control, the
scanner you used will NOT be able to read those
codes which also set the ABS light on.
my 2004 ford Taurus abs light turned on and then a message popped up
on my screen saying something with the brake system. I turned my car off
and then tried turning it back on and it didn't. What can i do?
I have a 92
Oldsmobile cutlass.  I have had the ABS light on for a long while
now, never had issues with braking till a week ago.  The pedal with be soft
one minute and hard the next and the parking brake light comes on if the
pedal is pushed hard.  I took it into the shop and they said that they
checked the brakes (front and rear) as well as the Master cylinder, and
everything is fine.  They said that it's just the ABS acting up but that the
ABS might cause the brakes to become soft and possibly fail???
My ABS Light comes ON after I start moving on my 98 Camaro SS. It didn't
come ON until I put bigger tires on the rear. I have 225/40/18 Front,
295/40/18 Rear. Could the Size difference cause the Light to come ON?
I have a 2003
Buick Regal, when i first start driving it everything is normal
and as soon as i hit the brake pedal i hear a grinding sound and then the
ANTI-LOCK light appears on the instrumental panel...Where should i start

Yes, different size tires will cause the wheels speeds
to be different. Now the computer sees the front and
rear at different speeds. Need to have all same size.
If you have the ABS light on, you have a problem with
that system. They should have checked for codes
and told you what was wrong there. The pedal can go
soft if the ABS activates which is a normal
occurrence, unless there is a problem associated
with the system. The red brake light is usually for the
parking brake or if the fluid level is low. If you're
having a problem with the pump or modulator valve,
that can draw down the fluid lower than normal which
would also cause a soft pedal and that light to come
on. I would recommend getting it checked out
thoroughly at a reputable shop.
More than likely, you have a bad wheel speed
sensor/hub bearing assembly. You should get the car
scanned to see which code comes up and that will tell
you which wheel is causing the problem. Also, the
wiring harness to the specific wheel speed sensor
can become corroded or have moisture intrusion or
become broken. Inspect that thoroughly when
changing a hub bearing assembly so you don't have
repeat issues.

I have a 1998 Pontiac Grand Am - Trying to troubleshoot a low track light. I
can be in park with the engine running and turn the steering wheel the
slightest bit - left or right - and the low trac light comes on for about 3
seconds and goes off. Is there a sensor or something I can check?
Sounds like a broken wire to one of the front wheel speed sensors.
I heard a grinding sound coming out of transmissions tail 5 minutes later a
louder grinding sound  then the ABS and Brake lights came on and it won't
let me drive , 2004 Chevy truck
Ya, the transmission is broke!
I have 2005 chevy Suburban 4wd. The trac control and abs lights came on
and there seems to be grinding in the front. Had the front brakes done 3
weeks ago so its not the brake pads. It sounds real bad when I turn. What
could it be and how much is gonna set me back?
You have a bad wheel bearing hub. That is the noise
and the cause of the ABS light.
I have a 2002 Buick Rendezvous with trac off and anti-lock lights on and
sometimes check trac system light also on. Had a scan, replaces rear wheel
sensor; lights still come on. What should the next step be?
The next step would be to check the wiring to that
sensor, that is if you got a code for the same wheel.
Hello. My ABS TRACTION and BRAKE light come on when I start up the car.
If I shut it down for 3-4 minutes and start it up again they do not come on. I
just had my brakes fixed about a week ago.
I have a class a motor home,workhorse,8.1 chevy. The brake light and the
abs light stays on all the time. It was on when I bought the unit used. The
dealer said they didn't notice it and they told me it was only a wheel sensor
bad. I purchased one sensor and went from wheel to wheel replacing the
sensor and didn't work. My mechanic don't work on large motor homes and
he told me it required a special scanner. What should I do next? Thanks...
Find a good mechanic to get the codes scanned. Did
you ever clear the codes after each sensor swap?
I have a 2004 chevy impala and my abs,tractive,service trans system goes
off and on. I hear a grinding noise when i first pull off and i can also feel it
when i put on brakes,what do you think is the problem?
You have several problems. Check the transmission
fluid level and condition. Have the ABS computer
scanned for codes.
My ABS light has been coming on intermittently for over a year. One repair
shop checked the codes and said i had to replace by bearings, but the
problem persisted. After taking it back 4 more times and him checking the
codes and telling me nothing is wrong, I took it to the dealership. They
checked the codes and told me the battery needed to be replaced. I
replaced the battery, but a month later the light was back on. What can
possibly be the problem. I can go months without the light coming on, then
all of a sudden it's back on. What can be the problem
I have a 2000 Grand Caravan. On way to work yesterday, Jan.19,2012, the
ABS light came on. Drove to a dealership immediately. After inspection, the
mechanic reported a FAULTY abs CONTROLLER  which costs about
$1600. The service advisor said that due to the age and mileage on the
van he does not advise to have it fixed. I was worried though if this affects
my braking capabilities. He says NO, and my brakes are fine. He even said
that I can drive the van for years without having the ABS repaired. Wow.
But is this true? I do not want to have AN ACCIDENT OR CAUSE AN
ACCIDENT. I do highway driving a lot.
He is correct. ABS only effects anti lock braking, such
as in the snow, wet roads, emergency braking.
Regular brakes are not changed.
I have a 2004 Pontiac Sunfire. Both front bearings went one shortly after
the other (about a month apart). But in between (a month after repairing
the first one) my service, abs, trac off light came on. They would shut off
when the car was turned off and back on and i could go about 10 miles
before  they kicked back on. Now they stay on regardless. Took a look at
the fuze....fried! Turned the on after taking it out and the lights disappeared
for the first time in 7 months. Didn't last long though...30 seconds later
there they are. Got a quote to have the abs scanned from the local
dealer...$180ish...ouch! Any ideas? 110,000 miles. Thanks! :)
If you mean the fuse was blown, then you have a
short circuit somewhere. You can either try tracing all
the wires and checking the function of the ABS motor
pack, or have it scanned and diagnosed by a pro.
I have a 2008 Mazda Tribute.  The ABS light just came on yesterday and
the brakes are acting funny.  It almost feels like they're not catching -
especially when going slow or turning.
Most likely a speed sensor or wiring problem. Have
the computer scanned to see what sensor is reading
I have a 2003 chevy Astro van and the abs light will not go off even though i
have changed the rotors and brake pads. Any solutions?
Well, first off, pads and rotors have nothing to do with
ABS. Get the computer scanned. Even though you
say read on the Internet everyone has an answer,
they are all guessing without a code to go by.
I have a 2005 ford Escape XLT... The ABS light is on but when I start my
car it is off for a few minutes before it comes on and my 4x4 light flashes
randomly on my dash. Currently there is no snow or ice so I don't think my
4wheel is trying to kick in. And the brakes work fine. How worried should I
be? I have to drive 5 hours away in 4 days does this need fixed first?
The reason the 4x4 light is flashing is because of the
ABS problem. The four wheel drive computer needs
ABS sensor data to operate. The ABS computer
needs to be scanned for codes. Possible a wheel
speed sensor problem. It it not dangerous to drive,
you just do not have anti-lock braking and possibly
cannot put it in 4 wheel drive.
I have a 2002 Ford Explorer 4WD. The ABS light is on and yesterday the
Check Engine Soon came on. This morning I take it to a local auto parts
store and they hook it up to diagnostics. They didn't give me a code but
said I needed a rear wheel speed control and also a Shift Solenoid B.
Those were the only things to show up on diagnostics, however the clerk
didn't know if that would get rid of the check engine/ABS lights.  Is it
possible the check engine light would come on for these 2 parts?  I take it
to my local dealer afterwards and they do diagnostics and tell me the same
2 things, but add on a front wheel bearing. I recently had all brakes/pads
done (within the last 3 weeks). Also the transmission has around 60K miles
on it. I forgot to mention this to my dealer but they tell me due to the age of
the transmission it will probably need replaced...for $2800. It has always
been well maintained and drives perfect..just those lights have me afraid to
drive it anywhere! Thanks for any suggestions!
I have a 2000 VW Jetta 2.0 and my abs light came on and my brakes are
sometimes jump when i press on them and i could hear it mainly in the front
driver side wheel i think so i went and got new brakes and rotors for both
front wheels and that didnt help the abs light is still on and still jumping but
now the brake light i believe is on its the light that has a circle with three
dashes on each side. So do you have any idea of what i need to do to fix
this problem? Thanks.
i have a 2006 ford freestyle limited AWD the traction light from the dash is
coming after 10 min,whats going on? Any idea to fix the problem? Thanks.
I have a 98 Dodge Durango. I bought it in February, I knew when I bought it
that the brake pedal was soft. I thought it needed brakes. The next day my
ABS/ brake light started coming on ocassionally. The brakes had been
replaced by this time. I have a bad cv joint and a broken steering knuckle
on the right side. I also have 4 different used tires on my 4x4. They are all
the same size but there are not 2 matching tires on the truck. Could any of
this be causing my brake problems?
A bad CV joint, broken knuckle and messed up tires ?
Ya, all of it !
