My left rear was doing that also. Working, not working. Then finally stopped. Almost like a wire or plug disconnected. I was running my truck real hard on trails too. I stopped doing that though.
I am having the same issue, but it is only the left rear. no matter what tire I put there it remains --
I have the resetting tool and my mechanic has an even better tool and the left rear will not respond.
I just know I can take a tire that reads fine in one location. Move it to the left rear...
Well it weighs a ton more. I will need to add stronger springs however, I plan on adding a 4wheel pop up camper to the bed. So suspension upgrade was always in the plan.
