ABS, trac off and service vehicle lights are on
If there is a problem with one of the systems, likely the ABS, it will affect those other systems. Have this diagnosed ASAP.
dude mine did the same thing its something to do with fuse's cuz when you take out the abs fuse al lights for trac off and service engine soon go off.
Check you fuse first. If fuse is good, you have a wheel sensor that went out. You will have to take it somewhere so they can tell you which one. The part should be about $80. It is built into the wheel bearing on that vehicle.
Front hub bearing assembly. I've replace both of mine. One at 70K, the other at 80K.
Bad wheel speed sensor in one of the front hubs. Around a $300 repair bill. Go to www.gaownersclub.com There are DIY hub replacement threads with pictures.
My Grand AM had the trac off light on and i found that the map sensor was unplugged as soon as i plugged it in the light went out and hasn't come back on since. That was like 4 months ago. Also if the air intake sensor is unplugged or bad it can throw that code and make the light come on.
