On the Curt TriFlex Trailer Brake Controller - 1 to 4 Axles - Proportional # C24VV the double dash display means you have a power issue. It can be that you are not getting 12V to the controller, or it can mean your ground connection is bad. You will want to check your brake controller wiring. White is ground and black is 12V power. You can use a circuit tester like # PTW2993 to test these wires.
