You'll first need to scan the computer to see which codes are actually showing up. (Autozone will do this for free) This will give you a place to start.
When you have a traction control problem, it's usually the vehicle speed sensor, or one wheel speed sensors has failed. The sensors can get cracked/broken by a rock, caked up with mud/rust, or the wiring/connector can be damaged.
Because you vehicle is a '03, the computer should tell you exactly where the problem lies. (Such as VSS failure)
What it won't tell you is why. That will require inspecting that particular circuit and sensor.
