Interesting. Thanks for sharing. My trailer brake module was replaced in July 2021 but my problem persisted throughout the rest of our camping season. Maybe they have revised them since then?
In my case, i would start a trip with trailer brakes and shortly after being stopped (sitting at a red light or on a ferry) the trailer brakes would stop working.
Thank you. Good to know. If my problems persist when I take out my camper, I will be going this route. We have a 5th wheel, so I installed a 7pin in the box. This will simply my wiring a bit. I ordered a 2022MY but canceled it last week due to fears of having the same issue as our 2021
My method is to disconnect the truck battery for 2-3 minutes and start over. It has been successful every time until I need to turn the truck off , at which point i will disconnect the battery again before resuming my trip.
hopefully this is true! Otherwise it'll probably be traded in( i realize there is no inventory at the moment). I don't trust the truck for towing anymore and have a hard time paying for something that doesn't do what I need it to.
