Tekonsha Prodigy Brake Controller ?'s

[CCiatteo]

Finally got around to installing the brake controller and taking my (new to me) full deck car hauler for a test spin (empty). Now I have a few questions.

Truck is in sig. Trailer is a 2007 18' open Bri-Mar. Controller is a Tekonsha Prodigy with harness to go from factory connection under the dash to the controller, no splicing or scotch-locks etc. Brake controller is mounted where the ashtray used to be and is level.

I followed the directions on setting the power levels on the controller and have the trailer wheels right on the edge of lock up. But I have a couple codes that flash intermittently and all occur over rough roads/patches at speeds in excess of 25mph.

I get the S.H. code which is a short while idle.

I get the codes -.- and _._ which mean the controller is mounted at an incorrect angle.

The brakes work fine, boost works fine, I can feel braking differences when I crank in more brake or boost. Reverse feature works fine. The truck/trailer connection is factory dodge 7blade RV style and the trailer connection is brand new. What could be causing these codes? Faulty wiring on the trailer itself? Or is the controller very sensitive to the road conditions?

I took a quick glance under the trailer and all the wiring appears to be unmolested and is in plastic loom, looks factory?

As soon as I get past the rough patches all is well.

Thanks for any input.
