Trac off / Service Traction control system

This light or indicator on the dash or message center is usually related to the ABS system, and
sometimes to the check engine light.

When this is on, the traction system is disabled. A problem in the ABS system is usually the
cause, and would have to be scanned for codes.

Sometimes and engine problem that causes a check engine light will also cause the TRAC OFF
light to come on certain vehicles. In this case, the PCM would have to be scanned for codes and
repaired first. Then the traction control system codes can be cleared.

I have changed my brake pads and rotors on the front and pads on the back but
my service traction system light still comes on. What else can I do. What else is
there to do to service the system? I  have a 2002 Montana Pontiac.
The pads and rotors have nothing to do with the traction
control system. You most likely have a problem in the
ABS. A possible bad wheel speed sensor. You need to
have the ABS computer scanned for codes.

Grinding noises when I press down on brakes and when I turn wheel hard left or
right  service traction system message comes on.
Get your front brakes and wheel bearings checked.

I have a 2002 Buick Rendezvous and I have a Service Traction system light that
comes on after a few minutes it goes off but my abs light and trac off light stays
on.. What would cause this and is it expensive to fix.

my front wheel wobbles  for a short time, but then rides ok. Is this caused by the
abs sensor.
Could be one of many problems in the ABS system that
causes this. Need to have codes scanned first.
Sounds like a bad tire. Have them checked or rotated to
see if that makes a change.

My abs traction off service engine light pops up all at the same time. The other day
I tried to start my car and it wouldn't start at all. Ended up push starting it, took to a
mechanic and transmission, fuel pump, ECT all ok. He said he couldn't find
anything wrong. Please help explain why my car is doing both of those!

I drive a 2005 Pontiac grand prix GT and while I'm driving reduce engine power
pops on my screen and when this happens once I brake at a light my gas pedal
stops responding in R N D 3 2 1 but responds in Park then my screens shows
service traction control. Then the car starts to roughly idle then shut off and it
takes me a while to get moving again. PLEASE help!
The throttle body on your Grand Prix is electronically
controlled and when it goes bad, the reduced engine
power light will come on and the vehicle will run rough, be
hard starting, etc. Also, you have what is called an
accelerator pedal position sensor that is part of the
accelerator pedal assembly. These will give the same
symptoms when it goes bad, too. Since it did set the light
on, you will have trouble codes stored in your car's
computer. This will help diagnose whether you need a
new throttle body assembly or a new accelerator pedal. It
would most likely need to be checked by a technician.

Monte Carlo, once I turn left or right at times, makes a grudging noise and Service
Traction System light appears, only does this once turning left or right slowly,
almost 80% of the time departing from a parking space as well as parking.

You probably have a bad hub bearing on your Monte Carlo. These have the wheel
speed sensors built in to them, and when there is a problem the trac light will come
on and usually the abs light as well. You can get the car checked for codes to see
which side is causing you problems. Also check wiring harness to sensor for water
intrusion and corrosion.

have a 2004 Monte carlo the ABS and Traction control light came on after doing a
donut in a field on night. I have at the wheel off and checked the connections.
Could there be a thrown bearing. If so how do i check to see if that is the problem.

I have a 2007 chevy Cobalt SS the 4 door model the traction control light comes
on all the time when I stay at a constant speed of 60-65 how do I fix it
Did you check wiring to all four wheels? You need to get
the computer scanned to find out what the code is. You
are just guessing it is a speed sensor problem. Could be
something else.

I have a 1998 Ford E-150 Econoline van... I've installed the following rear drum
brakes , wheel solenoids on the driver and passenger side as well as rear brake
lines. Also I installed a new brake line from the front main box where all brake lines
run from " I'm not sure what it's called but it's right under the brake line pump
/ fill reservoir.... Before during & after installing all this... I've test drove it on all
aspect I'm getting the same results, out a 2 block street approx 18 times when I
touch or hit the brake pedal I hear a winning sound kind of like " I'd you had.
Manual car & put it in gear with accelerating @ the same time, not a grinding
sound!!! That lasts like 2seconds its as if the brake pedal is rising or building
pressure... Then  immediately following that a knocking / pulsating sound is felt in
the brake pedal slightly heard... It goes through approx 8-12 knocking. Then @ the
very end it seems as it's relieved pressure or something. Kind of like when your
bleeding the brakes feeling !!! Does anyone have ideas or recommendations?I'd
greatly appreciate your time and direction. Thank you - William

i have a 2003 Monte carlo have had new brake pads and rotors now my abs and
traction system lights coming on what could the problem be now.
If the ABS light was not on before the brake repairs, it is
possible that the person that did the repairs has
damaged one of the wheel speed sensor harnesses.

I have a 2006 Pontiac Grand Prix GT and I recently had the battery changed.  Now
it is telling me to service traction control, service ABS, and service effortless
steering.  I'm thinking the problem is something to do with the fuse box...  
Considering the fuse box had to be moved change the battery.  Any suggestions?
They may have caused a poor connection under the
fuse box by moving it. This battery is tough to replace.
Check the fuses first.

I have a 2000 Pontiac Sunfire. The Service light, ABS, and Trac off light came on
after a while of driving. I didn't notice anything different while driving or any funny
noises. Whats wrong?
Sounds like an ABS brakes problem. You need to get the
computer scanned for any stored codes first.
