SVS, Trac and ABS Light on.. HELP

Hello Everyone,
Let me start off by saying that this forum is awesome..
Ok.. now for my problem...
On my 2001 Olds Alero (3.4) My Service Vechile Light, Trac Light, and ABS light all came on at once. I shut the car off and turned it back on and the lights went off. They come on sporatically but I would like to fix the problem before it gets worse. This all happened after I noticed a vibration in my steering wheel while im at the speed of 70mph...

Thanks!

Welcome to AF, start out with a scan for history codes.

While I agree with Shep to get to scanned with an ABS capable scanner you should check the wiring going to both of the front ABS wheel sensors. Mainly the electrical connector and look for any frayed wiring that runs along the subframe and lower control arm. The wheel sensor is part of the hub/bearing assembly but the intermittant effect could just be something simpler, otherwise you may be looking at a bad hub which is a common problem on Aleros.
