I'm trying to flash a tune and the autocal goes through its process. After a few seconds at 0% it shows error code 322. I'm doing everything correctly as far as I know. Anyone have this issue and/or know what I'm doing wrong?

Autocal is has been updated.

I've gone as far as removing the radio and info fuse as idicated that htose may cause interference.

03 Yukon 6.0L

any insight would be apprecicated.
