You know I just LOVE all these ARM CHAIR quarterbacks who don't even own a Motorhome, or a Cummins engine for that mater. The owner of the service center I used SHOWED ME THE READ OUT of what the code was and IT WAS FOR OVERDUE OIL SERVICE BY TIME, not mileage!
I have owned a motorhome with a Ford V10, have also owned a pickup with the GM 8.1.
Can't speak for Cummins or Dodge vehicles in general, but neither of my units would turn on CEL for an overdue oil-change.
The "change oil" message may come on after a certain period of time as well as mileage, but that's NOT the red light!
