Troubleshooting Hopkins Impulse Trailer Brake Controller Error Message OE
Question:
I have a Hopkins Impulse brake controller that, when I press the brake pedal, the number starts climbing and around 13 changes to what looks like a OE on the display. What does this code mean? Im towing a 2018 Aliner Ranger 12 with a 2007 Tacoma.

The troubleshooting guide for the Hopkins Impulse trailer brake controller does not list an error code "OE" but if the unit displays a flashing code "SC" this indicates a short on the brake output circuit or a defective brake magnet, which is unlikely on a new Aliner. Those error codes can sometimes be difficult to read. My Hopkins contact said much older versions has error codes E1, E2, E3 but not OE.
I suggest taking a close look at your Tacoma's trailer connector. Corrosion issues on (or even inside) a 7-way vehicle socket can lead to connection problems with a brake controller as well as with trailer lighting. Unplug the wiring connector from the back of the Tacoma's 7-way and check for signs of oxidation (greenish or whitish discoloration on the contacts). If you see anything other than bright clean contact surfaces apply an aerosol electrical contact cleaner like Caig De-Oxit or something similar that can dissolve corrosion. Once clean apply dielectric grease like # 11755 to those contact surfaces to protect them.
Also make sure your Impulse is mounted correctly as outlined in the instructions that I linked for you.
If you cannot get it to function I recommend replacing it with a reliable Prodigy P2 # 90885 and the mating harness # 3040-P.
