I have replaced all four Brake Calipers, Discs and Pads. Now the TRAC Light comes on and stays on after about 30 seconds of Driving. Whats causing this and how do I get the Light to go out?

Had mine on my sc4 i checked under the hood there is a harness to the air filter was pulled but I pulled up this and maybe it'll help you
