ABS and Trac Control Issues???

[SFStangGT]

So while driving, out of the blue my ABS light comes on and my Trac Control automatically turns off and I cannot turn it back on Brakes still work fine, though the ABS does not work. Any clue as to what it could be???

All tires ar the same size so i doubt one of the sensors is getting a bad signal. I put 373's in the rear end about 6 years ago and never had an issue so i doubt it has anything to do with the gears. I have a speed cal to correct the wheel speed from the gears.

Car has approx. 75000 miles and i have never changed the brakes. Still stops on a dime.

Any help???? Its been a while since i have upgraded anything, so this gives me a good reason to do so, without the Mrs. moving me out...

Same thing happened to my wifes 03 gt and it was abs controller. I took it and got the codes scanned and it came back bad controller. I found one on e bay for 50$ and swaped it out. the dealer want like 850 dollars for it. Hope this helps.

Could be anything in the electronic anti-lock braking system, separate codes are thrown from the engine management system, you need the dealership to read the codes. Could the module or any of the speed sensors.
