I am getting an error on my 03 LB7 when I try to read in my ECM from my AutoCal. I have tried Alt Keys, Assume ECM is locked, Try Additional unlock methods, etc. with no luck. I have my trace file on hand and my license backup file. What should I do from here?

Pull radio, info, radio amp fuses, check assume lock may be faulty and un click high speed. Sometimes it works.

Also think about any aftermarket equipment that may have been wired in to the data bus, these always cause problems on the LB7 & LLY.

I have already tried all of the things you guys have listed. I've also tried bench flashing it with no luck, so that definitely rules out any electrical interference.
