Check the pin on the brake away switch and see if it is pulled partially out. That is the usual cause of this. It has nothing to do with the controller, but acts from the battery. The controller still tells you that the controller is disconnected as that is true. Best to pull the pin out and push it back in again. If you still have a problem, it may be yo have to replace the switch. Not expensive and most RV places have them. Easy to wire up. Hope that helps here. Please get back to me if we need to dig deeper into this as all follow ups are included in our fee and fully expected.
