N.C. on a brake controller indicates that a trailer connection has not been detected while you are pressing the brakes of the vehicle. In almost every situation where we see this when a trailer is connected the solution is cleaning the pins of the trailer connectors and the connection will fix. Try that and let me know if that helps. I also attached a help article on troubleshooting brake controller installs for you to check out as well.
