The PL error code on the Primus brake controller # TK90160 indicates that power is interrupted when stepping on the brake pedal. Check the connection of the red wire. It should be attached to the brake switch wire that has power only when the brake pedal is pressed. If it has power at any other time then it is not the correct wire.

I have also included some links to testing and troubleshooting brake controllers that should also help.

Without knowing what brake controller you have I will venture to guess that the OL code you are seeing is an over load code. The OL or overload error code indicates a short in the brake output circuit. Start by examining the trailer connector. Make…
