I just attached the bluefire adapter to my 2010 Holiday Rambler Endeavor diesel pusher and I was able to retrieve the inactive faults (there were no active faults).

The faults listed were shown as 91-2, etc.

In trying to learn more about them, I have seen 91 followed by FMI and a number.

Can someone point me to where I may learn more about this?
