Went 950 miles since reset on ecm and can and the DPF light is screaming again...
Did a forced regen, and sure getting tired of this. Also have fault code 2777, which points to a problem involving the inhibit switch. The inhibit switch will not allow me to do a forced regen, so I have utilize Insite to complete the task. Insite says something about ecm programming for the inhibit switch, yet I had ecm flashed to the correct av10046. I'm thinking maybe I have a bad inhibit switch on the dash, since I can not do a forced regen when pressing the rocker switch.
Thx in advance

Someone can flash it with the right program, but that does not mean the inhibit switch setting is guaranteed to be correct. That is part of the adjustable features and parameters and if someone did not back them up and restore them properly, or has set the wrong address for it, then it can have some problems like your describing. It can also lead to the thing not performing rolling regens properly too if the switch is reporting it is in the inhibit position.
