I'm sure that at some point in the past I was able to display the check engine light codes on the dash by pushing a button or buttons. That said, I cannot remember how I did that and I need that skill again. This is a 2014 AC Revolution. Hopefully somebody knows this off the cuff and it will be quick and tidy. Thanks for any help.

If you have an LBCU, hold the selection button to the right for 5 seconds with ignition on.
Scroll down using the button to the Diagnostics section. From there you can get the Engine active engine codes.

Sorry if the above info doesn't pertain to your coach. I'm not familiar with American Coach electronics. Good luck.

Thanks, I managed to puzzle through it. I pulled the code that was causing my CEL and talked to Cummins. Apparently I've got a recall due that I didn't get the notice for. It was something to do with the emissions system and a NOX sensor reading. Anyway, it supposedly won't cause a derate so I can wait just a bit before getting in to service.
