Hi All,

I recently added a dsp5 tune to my '08 Cummins. I was having issues with the truck, so I loaded my original stock tune back in to do some troubleshooting. Today I went to reload the dsp5 tune and I'm getting error code $0312 and when the VIN, Serial, etc pops up it is showing all zeros. Right now the truck will do nothing.

If anybody has any insight I would very much appreciate it.
