Trac off, abs, svs...

[Marrko]

Ok here's the deal. I had a huming noise coming from the front and ect. and the trac off, abs and svs liths came on from time to time. I bought a new wheel hub, the noise disapeared, everything's great but i still get the trac off, abs and svs lights come on from time to time. so what else could be wrong? what could be causing them to light up?

P.S. When the abs, tracc off and svs lights come on, i stop the engine off and start it again and the lights dissapear... so any thought?
