Hey guys could use some help, tried to load a DSP-5 tune on to a 05 LLY. Truck has a CTS monitor, unplugged it, plugged in autocal, turned key to run, and proceeded to attempt to grab stock file and got the $0281 error. Went made sure fuses were all good and all accessories were unplugged, everything checked out. Attempted a few more times and made sure the connector was seated good. I then made sure boot block and firmware were up to date which they were still getting the error, so wanted to see if anyone had any ideas? Thanks in advance
Also to note did not pull any fuses, thinking that is probably my issue
