This (or a similar message, depending on trim) will only show if you're in the right screen. My 2019 LTD will only show a similar message if I'm on DPF screen and even then it's not a mandatory to keep driving. If you need to stop, the regen will resume the next time you drive it until it clears.
There are different messages for different conditions.
Normal active regeneration messages only appear on the DPF screen in the EVIC.
If there are unique conditions that require driver intervention, those messages can indeed “pop up” on the dash, regardless of what screen you’re on. They are accompanied by a “ding”
For instance:
“Automatic exhaust system regeneration in progress”…..indicates a normal active regeneration cycle triggered by soot load or by the 24 hour timer, and is only visible if you scroll to the DPF gauge in the evic.
“Automatic exhaust system regeneration in progress continue driving”….indicates that the normal regeneration cycles are either not effective or have been interrupted frequently enough that they need to complete. This message is a “pop up” style and will appear on the evic regardless of what screen you’re currently viewing, accompanied by a “ding” or “chime”
In terms of the active regeneration cycles being interrupted and restarted, yes they will indeed “pick up where they left off” but it is important to point out that this is absolutely
not the most ideal condition. When at all possible, you are
far better off allowing the cycle to complete once it has begun. Especially if you’re able to keep it at a constant highway speed. Repeatedly interrupting the cycle can lead to a DPF not fully getting cleaned out and soot levels slowly rising. This is especially true in scenarios where the truck will see a different style of duty cycle on the next start up. For instance: you’re on the highway about 10 miles from home when the regen starts, so you let it run until you get home and then park it and shut it off (probably was about 50% complete). The next day you start it up and run down to the grocery store for some food and the truck starts the cycle again but sees a widely varying speed and rpm duty cycle in that case. The regen cycle is still running but you’re not getting as efficient a clean out with the engine fluctuating. You get back home and it’s still not complete so you park it again. And on and on.
The feature that kicks the cycle back on to complete is a fail safe but it is not the most beneficial for DPF health.
When at all possible let the cycle finish, preferably at highway speed.
