Doesn't the high idle only engage if you have the setting turn on in the DIC?
On my 2009, elevated idle has to be enabled in the DIC before it engages at the OAT temp that causes it to engage

How does a person "force" the truck to regen?
What year is your truck?

This thread has been interesting and a learning experience for me. My 2020 Duramax and first diesel vehicle was idling high yesterday. I thought it was too warm outside for it to be idling higher than normal. Now I understand why! Thanks for teaching this old guy something 🙂

That’s the way mine works, and there have been a few trips that just weren’t allowing a full regen to occur. It’s maddening to see that happen several times in a row. I wish when the DPF gets above about 80% soot load, it would allow you to start a manual regen. There have been too many times that if the ECM would just start the regen at the beginning of a short trip, it would have plenty of time to finish by the time I reach the destination. Instead, it seems to wait until just a few minutes before I get to where I’m going. Then it only has time to burn off about 10% of the soot.

My bet is that the programming change of initiating more regens is because our trucks seldom enter into a situation where they can do one long complete regen before we either reach our destination or enter into traffic conditions that interrupt the process.
