The TCS is because of the abs not working, I can almost guarantee it! I had wires broken on a wheel sensor, and my abs light was on, and the tcs as well, when I changed the wheel bearings (speed sensors) They both went off, and now my tcs works properly again. There was a thread here somewhere that explains how to test you abs system for bad wires and such.
So its probably safe to say thats not the problem with mine because my abs works fine right?
