Hey Steve, a 5.H error code on the Tekonsha Primus IQ Trailer Brake Controller # TK90160 means that the brake wire sees a short during idle condition - This can also be caused by using certain test lights or non-Tekonsha testers.

To fix it you're going to need to dig through the wiring and look for the short. It's not necessarily the most fun thing to do, but it's really the only way to fix the situation.
