Can anyone tell me where a list of OBD codes for my 2115 Diesel can be found?

Not specifically for your van but sites do have them and they include the diesel ones.

Thank you. Bought my first scan tool

Congratulations. It is something that should come with every vehicle. It lets you see inside the "black box" and have some idea what is going on. My code reader-reseter is about 8 years old and cost $60 then. It has saved me about $600 in code issues on my 4 Runner and a few on my former F150.
