I had my oil changed a few months back, and on the way to having it done, this message came up.

I can't for the life of me figure out how to clear the "Service Required/See Dealer now" message from my overhead.

I have tried the brake pedal twice, and the gas twice turns off and restart.

Nothing I even tried to use my Scanner (I have a Snap-On).

It clears it but comes back in about a week. I'm new to the diesel life coming from a 5.7 Hemi.

I'm not afraid to get in there, but this is a new world for me, and I'm trying to learn everything I can about it. I've searched other Cummins forums, but nothing is helping.

I'm just afraid my tune has to be uninstalled so that truck can be returned to stock mode and then reinstalled after the message clears; my tune won't reinstall.

I have the H&S XRT Pro on the truck.

With them no longer in business, I can't afford to have the truck go into limp mode because it won't retake the tune.

Any help is appreciated.
