"Service ABS, Traction Control, and Stability Control"

I have a 2004 Grand Prix GTP Comp G with 55k. I haven't even solved the other problem I posted on a previous thread and I already have a new one. So it usually happens at low speeds when turning the steering wheel. While turning the steering wheel I can feel a bumping feeling. I then can hear what sounds like the rotor/hub assembly rotating from the front of the vehicle. Then on the DIC says "Service ABS, Traction Control, and Stability Control". It then shuts off my traction control (I can't turn it back on) and the ABS light stays on. I can shut the car off and the lights go away. When i start going again and I turn they come back on. It has been getting worse and more frequent. I have replaced both front hub assembly's so I am wondering if maybe my speed sensor is bad? The other thing I was thinking is maybe there is a brake sticking. Any thoughts would be appreciated, thanks.

They make abs/airbag/obd2 code readers now. Make sure you check that your vehicle year and model are supported. I got one from amazon. OTC 9450 $115.

I had a traction control/abs/stability control lights. Ended up getting a junkyard abs module for $75. Solved my problem.
 
**Update** I took my chances and bought a new hub assembly(It was under warranty). When I removed the drivers side front the wheel speed sensor connector was all messed up. Installed new hub assembly and problem fixed. Thanks for the suggestions though.
 
I have a 2005 Comp G with the Traction Control, Stability Control and ABS service lights coming on and then being disabled. Thought I would let you know my experience. Took it to a local shop and had it scanned and got codes "C0035 - LF Wheel speed sensor circuit malfuntion" and "P0703 - Brake switch circuit." Over the next few days I will change the speed sensor and give you guys an update.
