Is my brake controller shot?

Just took the camper out for a short trip to dump my tanks and noticed that it was pulling harder than normal. I look down at the brake controller (prodigy p2) and the numbers on the readout are going all over the place without even touching the brakes. I get home and put it in park and it is still doing it. I went back to the wheels on the camper and sure enough you can hear the brakes working. So do you think my controller is shot or could it be a bad connection somewhere. Thanks
