Is it under warranty? If so, let the dealer deal with it.

If not, do you have a scanner that will do ABS codes? Harbor Freight sells one for around $125 that will do ABS. I also believe that JScan with a OBD dongle will too.
Have you made sure that you have not bent your drag link/tie rod? Is the steering wheel centered?

If all is straight and the wheel centered, you probably have a bad wheel sensor and need a scanner to figure out which one is bad.

Thanks for the info. No warranty left except the power train...
I will get a code scanner and see. Thanks for your help.

As mentioned....is your steering wheel straight when you're driving straight? If not, your steering angle sensor will continuously think you're in a skid. Easy enough to correct with the adjuster.

As to ABS scanning, I've got a J-Scan and absolutely love it. It helped me pin point which abs sensor was not working and after I cleaned it, I was able to push it back in and spin the hub to see that it was again working correctly. Parts cost = zero.
