Hey new poster , just picked up the truck used 2012 ram 3500 longhorn. I tow a small tandem axle utility trailer with almost no weight I set it at 3.0 like I had in my f 350 before and locked them. With the controller at 0.00 I still lock the tires at low speed in rush hour traffic. When I hit the brake it shows 10 ?? When I manual slide the bar nothing happens it only at low speeds like pulling up to a light etc?? I had to pull the cord today in traffic I was dragging the tires everywhere? Could it be the hill assist ?
help locking up trailer brakes with controller at 0

I would go into your EVIC (the screen in your dash behind the wheel) and see if the tow is set for "Heavy electric", and if so, change it to "Light electric", then find a setting that works for you.

Maybe pull the battery cable and reset the computer leave it off for good 10 min. See if that does anything for you. Are you useing a wiring adapter? Such as a 6-7 way? You can always get a volt meter and check the output of your trailer plug on your truck. And does the truck have multiple plugs one in the bed for goosenecks? I'm wondering if someone messed up the wiring when installing the one in the bed (if there is one). Good luck sounds like a problem you will have to start from square one and check everything.
