Find the switch on your dash, first make sure it’s not flipped up for some reason to disable a regen, then push it down and hold it for a few seconds. It should idle up and start a regen while you’re parked.

, um, you know, I'd go through a roll of electrical tape covering up all these "warning" lights. Those instructions on the visor( continued on passenger visor) may as well be Chinese to me. No, you can't teach an old dog new tricks. I remember when just the shift pattern decal caused confusion.
Numb and nextgentrucker Thank this. -

Most companies don’t do proper maintenance on the emissions systems.
The Cummins system requires a DPF cleaning every 150,000 miles. Most of the others are the same. Be surprised how much of the problems get avoided by that service.nextgentrucker Thanks this. -
Feel free to look in the truck's driver manual or Google your truck make & model & a question.
nextgentrucker Thanks this.
