Troubleshooting Tekonsha Brake Controller that Won't go to Sleep After Inactivity

Question:

I put this controller on my 04 nissan titan ex about 6 months ago and it worked like it was suppose to would go to sleep after about 15 mins or so. Now about the last week or two it will not shut down and go to sleep. I checked all the wiring and checked fine I even tried unhook the battery with no success. could there be something that I am missing or could it be something with the controller. Look forward yo heating ftom you on this issue

The P3 brake controller part # 90195 is supposed to go to sleep after 15 minutes of inactivity. Yours is most likely sensing some type of activity to keep it "awake." This could be corrosion on the trailer connector causing a slight short which makes the controller think a trailer is connected. Or if there's a short on the wiring to the controller that could be the culprit as well.

Keep in mind that if you are opening the door on the truck or touching the brakes at all when checking on it that could potentially wake it back up.
