On my 2004 Deville the ABS and Traction control light comes on seemingly after hitting a bump in road. It does not go off until the ignition is turned off. I replaced all brakes and checked brake fluid and wires leading out of wheel bearings at the front. Brake lights,etc. work as required. I changed left front wheel bearing a couple years ago. Does anyone thing maybe the right side front wheel bearing unit may need replaced because of the ABS stuff? This is driving me nuts any help will be greatly appreciated.

Pull the codes as described in sticky at top of forum along with the definitions of codes. Inlcude if current or history. There are links to code definitions in the sticky, otherwise you're just guessing and throwing parts at it.
