I have a new to me 2012 Peterbilt with a deleted Cummins ISX 15L that I don't have access to the history on. The jakes are not working at all. The computer I have is not communicating with the ECM thru the 9 pin. I am wondering if the ECM was "locked" during the deletion process? So far we've checked fuses and found a few missing. Thoughts?
