C0020-15 abs light, traction control, brake light on

Recently sold my 01 powerstroke and got into a 15 powerstoke for cheap but got a few issues to iron out. Got everything fixed except this. Been on since I drove home, first it was front left abs sensor was bad, replaced it lights went of then on then off then on then off then on permanently again. Code was a c0020-15 I am going to check park brake connection tonight but any other ideas on this code?

I would check the wiring on that sensor you just replaced, might be a ground issue.

Was it the motor or the controller that was shorted? How did you test it?
