Service electronic throttle control on 3.0 eco diesel

Experiencing similar issue currently, what ended up being your fix or remedy?
Appreciate any input you can provide!

Not sure if it is fixed or not yet, but haven't had it trigger since the ecu flash at the same time as the HPFP replacement a month ago. Went out to the normal hill where it kicks off and no CELs. I hope that I am lucky enough for such an easy fix, but expect it will return when outdoor temps get back to normal and the jeep is running warmer for longer.

I have a 2021 Gladiator 3.0 eco diesel. Jeep runs great with 37" tires with the mini tins to adjust tire size. The problem I am having is when pulling a trailer, my jeep codes out and then puts me in limp mode until I pull over and cycle the motor three times as per the book to clear code. Seems like it only occurs when I get speed above 65mph. If I stay below that speed all is good. I have tried unmarrying the mini tins and with it on jeep but nothing changes. Any input from anyone would be great because the dealer says no codes are in ecm and can't figure it out either.

Sorry for the necro post y'all, just hoping you might have some favorable news to share. We finally made it to our destination, but the frustration and uncertainty have definitely impacted the experience . Appreciate any feedback you might be able to share!

They refreshed my ECU a while back and issue has not occurred again. Pushed it pretty hard a few times with no issues. Maybe you can get into a dealer to help out. I always carry my code scanner to reset the engine codes. That worked for the previous times it went off.

Whelp, seems there weren't any stored codes, just the lit CELs so there wasn't much the tech could do aside from clearing things out. He was aware of the issue, but said there doesn't seem to be enough data on it in the community to figure out what's going on.

Fingers cross for the trip home...
