Dogpatch The two signs I notice is engine makes a slightly different sound and the smell of the regen cycle. You may miss it if you travel a lot on the highway when it occurs, but you sure know it in the City when it does. Once you recognize it, you’ll know it.
The more highway miles, or constant rpm, or as some have suggested under load, the less it needs to regen.

Isnt there an EVIC warning that says "drive normally at highway speeds for 45 miles" or something like that?
Not normally. Only if you’re driving style causes the DPF to get extremely full.

Active is when the ecm directs the system to inject extra fuel to greatly increase the ehat in the DPF to burn off the soot, passive is when normal operation raises the temp in the DPF to burn off the soot, this happens under heavy steady state work loads, like towing/hauling heavy at highway speeds for long distances.

So, just because you've never seen any message pop up, doesn't mean that regeneration hasn't happened, it's an ongoing process.
I appreciate the education in the regen process. To clarify, I've never had an active regen due to the reasons you mentioned.

upflying 6000 miles on mine, never had a regen to my knowledge.

Electrojake FWIW my truck doesnt regen either. I'm no mechanic but this is the way I figure it...

I seldom run unloaded and do 90% highway driving.
My post turbo EGT's pretty much stay between 800F to 900F.

It is my assumption that when the Cummins engine is run under the conditions that it was truly designed to operate under it runs clean enough (hot enough) to not need raw fuel dumped into the exhaust system (a regen) in an attempt to simulate proper EGT's to burn off soot, thus when properly loaded regens do not occur.

I monitor regen status and pre & post DPF temperatures with a CTS2 mounted on the console.
Truck info is in signature.

Mine only comes on the ‘messages screen’. I thought the same as you but left that message screen up and sure as heck, it happened.
