I went wheeling in the bush for 4 days. The Ultragauge showed an unfamiliar error code. Unfortunately, I had no idea of what the error code meant as I had no internet access at the time.

Now that I am home, I decided to compile check codes into the attached spreadsheet. I now have a printout of the error codes stored in my glovebox (together with a hard copy of the RAVE and parts catalog).

The list includes the generic OBD codes as well as codes specific to the Disco. I hope some of you may find this list useful as a back up.
