My TCS,Emergency Brake,and ABS lights come on and TCS goes off after the car has ran for a small amount of time. There is a problem that I can't find and it's really irratating to see my idiot lights come on and the car runs fine.

Roger that, been there done that plus I replaced the front hubs to make sure the internal speed sensors in the front hubs weren't causing the problem to occur. I've spoke to a speed shop owner and several GM dealerships and they said it could possibly be ECM that cost over $900.00, Go figure huh!

I had the same problem for a while and the problem was just that my battery was weak Put a new battery in and it worked fine. Might not be your issue but wouldn't hurt to check it before spending money.
