There is no message or signal that indicates regen on my 22, even with ForScan changes. I bought a iDash gauge, and with that I can monitor the DPF %, which is not actually spot load, but the % of the 500 mile regen interval. It also shows ”ACT”ive or”OFF” for regen status.
With ForScan, you can add a monitor for DPF soot load %, and you can add a toggle to turn “Automatic Regen” on/off.
I use the iDash to watch when the truck is approaching the 500 mile trigger, and will turn off auto regen if I’m not in a position to let it run completely. I’ll turn it back on, when I have a chance to run about 25-30 miles at highway speed. It seems every time I get to the mileage trigger, the soot load is still less than 70%.
