Tcs and the little triangle with an exclamation point are both on. The triangle with the exclamation point in it is always on but the TCS light comes on after driving for a minute or so. What causes this? I've tried the TCS button and nothing. I've disconnected the power and nothing. Any other things I could try?

 

get it scanned for codes. there is easily a dozen things that could cause this. only visual that you could possibly due is look at each wheel speed sensor wire and see if something broke it.
