The Tekonsha Primus IQ Trailer Brake Controller # TK90160 that displays a flashing S.H shows that there is a short on your brake wire. There is not a reset button, but unplugging the controller for 15 minutes will allow it to reset. If after resetting, it still shows this code, I recommend tracing your wires with a circuit tester like # PTW2993 to check the wires for continuity and find the short then replace the wire as needed.
