Hello, thanks for writing in. If that was the only wire cut, the butt connector may not be sufficient to attach the wires together and they may have to be soldered. Some systems watch resistance readings through the circuit and high resistance may cause a fault. Make sure the 2 pieces of wire that are attached are the same color. If you need some help with this, consider hiring an experienced technician like one from YourMechanic to go through the wiring and check the system for a possible fault code that may shed some light on the problem. Best of luck.
