ABS light came on and also the Advanctrac light....says check ADVtrac.

There are many sensors on your anti-lock brake system, as well as on your traction control system. Sometimes one giving a signal will set off the other one. Unless you are can physically feel any symptoms, then a computer test is really the only way to tell what the problem is. Many auto part stores offer to check the computer, and many of those will do it for free. One you know what the computer says is wrong, you can have the problem repaired. You can still drive your vehicle, but be aware that it is highly possible that your anti-lock function as well as the traction control system may not work. The anti-lock keeps your wheels from locking up if you slam on the brakes. The traction control diverts power and/or uses the anti-lock brake system to reduce braking on a certain wheel. I would imagine that there is a problem with the anti lock brake system since it is used in the traction control system. Hope it turns out to be small!
