What Does the Er Code On the Draw-Tite Activator IV Trailer Brake Controller Mean


What does it mean when the er code is flashing without the brake pedal being pressed? It goes off when brakes are applied...


Helpful Expert Reply:

The "Er" error code on the Draw-Tite Activator IV Trailer Brake Controller part # 5504 means there is an internal problem with the brake controller therefore it will need to be replaced. That said, this will be a great time to upgrade to a proportional brake controller which will outperform the time-delayed one you have now tenfold. For this, the Draw-Tite I-Command Trailer Brake Controller part # 5535 is a great cost effective option and it will use the same plug as the Activator IV which makes for a plug and play installation. If needed, it can also be transferred to a new tow vehicle in the future and it comes with a lifetime warranty so long as you have your proof of purchase.
