Today, most new vehicles come with either an ABS or a traction control system. A problem in the ABS or traction control system is usually indicated by a warning light. When the ABS warning light is on, it means that the ABS has been shut down because of a mechanical or electrical failure.
The traction control uses the ABS wheel speed sensors (1 on each wheel - usually in the wheel bearing assembly). The speed sensor is for your speedometer. Do you have an ABS light on too?
for check engine light to blinks is you have a serious misfire fix the misfire. traction control by ABS system when there is serious misfire and you keep on acc. then ABS module will turn on traction control light
You would need to get the body computer scanned for trouble codes to proceed with testing. When there is a problem with the abs system, the computer will disable the traction control too since it uses the abs system to function.
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.
abs pump motor control fault...dealter got parts from wrecker (lot cheaper) already spent close to $2000.00 to repair traction/abs..messages kept coming on so they finally diagnosed the above problem...we will see...
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.
I had this problem when I change dsmy rear brakes and accidently disconnected the electrical connector for ABS/traction control. Make sure they are all seated well..........
An ABS sensor DOES affect the traction control system. Traction control uses these sensors to determine if a wheel is losing traction. A bad sensor will cause both the ABS and TRACTION lights to come on.
The CHECK ENGINE light however is going to be a seperate problem.
