2015 prostar won't turn off and revs to 20 Rpm and smokes

Wht engine? It almost sounds like a run away motor. But you said you reved it up

 

Turbo seal went most likely and it ate its own oil .. not looking good unless it was a freak electronic issue

 

Mine did that, but it was a Freightliner. Never figured out the cause. Had to use the battery kill switch to turn it off.

 

Could be stuck injector or turbo seal. Was it white? Don't let it run away if so you will be rebuilding engine

 

Push in the clutch, put it in 9th gear and ease out slowly...it'll stall. Sounds like an ecm gone nuts issue, Skynet taking over your machine...or 18 wheel version of "Christine"(old 80's movie about a possessed car for those of the younger generation)

 

Can't wait until hackers start playing with the ELD trucks that are tied to cellular or satellite data connections LMAO

Direct truck ECM access through the ELD
