Wire hanging from drivers side wheel, ABS and service traction control and traction control is off are on

I saw something hanging on a closer look it was some sort of wire with a connection. I unconnected it and the one piece was ground down to almost nothing. I was wondering what it could be on the driver's side front wheel some sort of wire with a connection. Took off the bad piece and zip tied the other end out of the way this wire has something to do with the wheel. I do have ABS light on also service traction control and traction control is off. When I push the button, nothing happens it's off all the time been this way for some time now.
