[QUOTE="KCsJKU, post: 426739, member: 17751"] I forgot to come back and update. Everything I read, which there wasn't much out there in regards to these codes, was a loose negative battery terminal. I double checked and sure enough, my negative terminal was loose, but was as tight as I could get it. So I replaced my terminal with a brass terminal and was able to tighten it down. I cleared the codes and so far, we haven't had a repeat of the issues. It's not a DD so I haven't gotten that many miles on it since replacing, but hopefully that fixed it. I had the battery replaced 6 months ago and didnt notice any issues with the terminal then. [/QUOTE]
