About an hour ago, I removed everything so I could get to the alternator to check the plug. It all looked good, with everything connected properly. I scanned for codes again, and got the same message when checking "CDI 3 Common Rail Diesel Injection 3" I got- "Fault in communication with ECU"
I tried clearing codes in other modules, and they cleared just fine (mostly under voltage codes). I believe this is all related, but have no idea how to fix it.

EDIT: Also, the alternator is charging at 14.6 volts +-
