The traction control light as well as the parking light as well as the abs light comes on when i start my car. don't know whats wrong

One or more of the sensors in the wheels that are responsible for these functions is faulty. It is sending a signal that is mucking up the calculations that control the brakes and engine for traction control and anti skid. All of them need to be checked!

Your abs and traction control lights should only come on when you start to slide while breaking(ABS), and when your wheels spin in place when excelerating(TC). If those 2 things don't happen, which with some people they never do, you should never see the lights come on. Only when those mechanisms are in use do the lights come on. And they will always flicker as that is what abs and tc are, intermitant surges to break up the constant. ABS does this for obvious reasons...anti lock break, so when you slide, the abs "taps" the breaks in short bursts so they don't lock up. TC "taps" the exclelrator when it slips. Those "taps" are what trigger the lights on your dash, which is why they flicker and don't stay on.

bad wheel speed sensor or wiring to it open or shorted. just fixed same ABS & Traction Control problem on my 2001 Chevy. No matter make or model the systems are pretty much the same.

ABS and TC work together, a problem with either one of these will set both lights.

If you can get a ACTRON Code reader 9185 it will read Gobal and ABS codes. Don't know if your local auto parts store will be able to read ABS codes for you. I repaired mine for $140.00 no more problems - take it to a dealer and you will be looking at $800.00 plus.

good luck

You will need scanned the ABS Module to know exacvtly what fault code is stored there; with this copde number we could send you othyer details to solve it. Generally is the Speed Wheel sensor go to bad or loss connections.

Keep in touch.

The ABS control Module is going bad, that all, since the ABS and traction work together you will get both lights on. Take to a mechanic, expect to spend about $500.

If brake pedal is chattering or pulsating it is most likely because you need either front or rear rotors, or both. They are rusted or out of round. If there is something wrong with either your abs or traction control,the abs or traction control light will come on & stay on. As soon as these lights come on, it automatically disables abs or traction control. If you would like to take out fuse that disables abs or traction control circuits, it will leave the lights on.You just wont have their functions. If by some strange condition your chattering goes away, then there is indeed something wrong with your abs or traction control.Fuses are labeled abs or traction either under hood or in your fuse panel in car.

If you have abs sensors at the wheels, have them checked. Usually abs & trac control work off these sensors

ABS and traction control really are only for panic stops and if your tires slip on wet surface's and yes each tire has a sensor on it. However if the brake light comes on this has nothing to do with the ABS or traction control lights. It's not a parking brake light. This light tells you, you have a serious brake problem.

The traction control system is controlled through the Anti-lock brake system. The way it works is if one of your wheels starts spinning the ABS applys the brake to that wheel to transfer power to the oppsite wheel that is getting traction. If your ABS is bad then your Traction control won't work. To check it I would find a parking lot on a wet day. In an open space mash in the gas. if you hear the ABS system kick in and you don't squall the tires then your good. My guess is you won't. What I would be worried about is will my ABS work. When checking the traction control is a good time to check the ABS. Acclerate to around 15 mph, then mash the brake as your live depended on it. If you hear a motor run and feel a vibration or grind in the brake peddal, then it works.

ok your problem is that your brakes are under force you shold get new brake pads ok
