DPF and Regen process

DPF and Regen process
If the solid "DPF" light for the regen comes on, let it run! Don't panic! Leave the truck running. You can drive it while its going. Once the light goes off, the truck can be turned off if you were waiting. This is the process 99% of the time.
Never ignore a flashing "DPF" light. If its not pulled over and put into park within the timeline, the truck can malfunction! You have about 30 minutes to pull over.
Most regens are complete within 20 minutes!
