So here is my situtaion. Removed the exhaust on our 2012 chevy silverado 3500 dually and installed a delete pipe, removed the def system and purchased an efi live delete tune. When i went to do full flash the autocal checked to 100% and went to tune the truck and it got to 1% and failed with an error code 0281. I looked over the wiring checked the fuses and battery voltage and found nothing. Tried flashing it multiple times with the same outcome, it would flash 1% 0% 1% error code 0281. So I broke down and ordered a new factory programmed ECM. Installed the ECM did the key relearn process and the truck fired right up. Figured the issue was resolved so I went to try the flashing process again. Same thing happened, 1% 0% 1% error code 0281. My buddy came over and we both checked the obd2 port and wires, no issues. Finally found a blown trailer brake fuse. We fixed the fuse and still the same issue, error 0281. We called duramax tuner and they said to try pulling the radio, amp and info fuses then try the flash. My issue now is once the autocal throws the 0281 code the truck goes into some kind of anti theft mode where the cel light and glow plug light are both dim or half lit and you can't start the truck or anything else. I'm thinking with the trailer brake fuse fixed and the radio, amp and info fuse removed the truck might flash but it won't as long as it's in this anti theft mode. Does anybody else have any experience or info with this kind of situation

Did a little research and found some other vehicles that had dim cel lights and found it to be a bad ecm? Anybody else know anything about this. How would the autocal fry the ecm at 1% flash?? Need some help asap I have hit dead ends everywhere I've looked and can't afford to keep throwing ecms at the truck
