with these lights on then you will have to see what codes are in the abs and pcm module to find out what the problems are.the abs module will activate when the traction control lights come on.this can also cause a noise and pulsate in the brakes pedal.
The ABS and Service Traction system may be due to bad sensors or signal reaching the ABS/Traction Control computer. The grinding may be due to uneven or unsmooth rotors, and/or worn out pads or shoes.
I would recommend that the entire braking system be diagnosed at your local dealer or brake service facility.
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 your ABS light is on then you will have to get the codes read to see what sensor is giving you the problem.The ABS light being on will also affect the traction control and brake pedal going to floor.Auto Zone will check codes but I`m not sure if they do ABS codes.They don`t charge so it wouldn`t hurt to ask.After you get the codes you can post back and I can help you find the problem.Good luck.
Could possibly have a bad connection on a wheel speed sensor. This would cause an erratic reading making the ABS light come on because the system thinks a wheel is either slipping or dragging.
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.
the anti-lock brake system is part and parcel of the traction control system. the abs has a $750.00 valve located in the engine bay on the right side (as you face the car from the front) the driver's side just behind the headlight. i had a mechanic who took it upon himself to remove, dismantle and clean and reassemble the unit, all to no avail but also without expense. the cost of the part was prohibitive since Blue Book on this car is just about $700.00. it will run and brake just fine without the abs or the traction control system either.
You need to have your brakes inspected by a professional. The lights indicate that ABS and traction control are not working...although brakes will work without these features, a humming noise can indicate more problems to come.
