Traction System TRAC OFF Light Questions And Description
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 tractions 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 computer 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.
ANSWER: 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.
Could be one of many problems in the ABS system that causes this. Need to have codes scanned first.
My front wheel wobbles for a short time, but then rides ok. Is this caused by the
Sounds like a bad tire. Have them checked or rotated to see if that makes a change.
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.
I 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.
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 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?
You need to get the computer scanned to find out what problem your car has in then ABS system.
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.
I have a Pontiac Aztec. The service traction system light is on. When I press the
brake pedal, sometimes it feels like it's grinding or shaking, and it sort of tries to
push upward under my foot. However, I don't have any trouble stopping, and the
brakes and rotors have just been replaced (replaced after the problem started).
You have a front wheel bearing / speed sensor or wiring to one of those sensors bad. Pads and rotors have nothing to do with ABS or traction.
Chevy Malibu. My diagnostic codes are P1125, P2125, P2138...do
all 3 codes mean I only need a APP sensor?
Yes all these codes do point to the accelerator pedal. It is becoming quite a common item fail. But one other thing to check is a connector that I have seen problems with. Open the drivers door and on the side of the dash you will see a panel. Remove that and look for a flat electrical connector. Disconnect that and look for any signs of water. It may be actually went or the terminals might be green with corrosion. Especially check this if you have a sunroof since we have seen those leak down into that part of the dash and corrode the connector. If it looks okay then just replace the gas pedal.
I have a 2006 Chevrolet Cobalt SS 4-Door Sedan, and occasionally (but not all the
time) my ABS light comes on and I have to restart the car to get it to go away and
then it may or may not work. Further, my traction control light will come on at slow
speeds or in combination with the ABS failure. I read earlier comments and I think it
may be a bad wheel speed sensor. What do you think? Thanks
There was probably some water intrusion into one or more of the wiring harnesses for the wheel speed sensors. If this is the case, it can cause corrosion which will require harness replacement. I'd recommend scanning the car for codes to see which wheel or wheels is acting up.
I got a brake line replaced and repaired a year ago. It was leaking brake fluid. It
happen again last Friday,why? This is on a 1995 Ford Contour.
If the new line / hose replaced last year was not just rubbing on something, then it could be just a cheap part or contaminated fluid- if you are talking about a rubber line that is leaking.
