06 Write Fail

Can someone explain to me what I am missing. I changed a few things in my stock file that I saved a copy of. The things I changed were at what temp I had the fan come on for ECT and TFT. I tried to write that tune to the truck but it failed. So i put it back to the stock file and it was successful. So then I just tried changing one parameter. I changed the rise temp threshold for the transmission from 240 to 205 saved the file and tried write again but it failed. So I went back to the stock file.

Forgot to attach the file.

Is there some type of verification that needs to be ran on a tune file before it can be downloaded to the vehicle.

update vcm, resync the mpvi, restart the computer, and submit a ticket to support. that's the options these usually flash with no issues

Did you pull out the fuel pump relay

I was able to get this resolved by updating VCM Suite to the latest revision. Thank you for the responses.
