INPA shows the same 2DE1, 2, and 3 codes but just as you mentioned, 2DE1 error now says it will not cause the MIL.
Thanks so much for guiding me in the right direction!!!! I have struggled with this issue for a couple of months.

No Problem! Glad to help. I hope someone is able to explain why this works for us. I noticed maybe a slight difference in performance between the two available tunes, but hopefully there isn't.
