Error code when trying to tune

did you run the Update Agent to update your Trinity to the latest updates/fixes?

make sure anything aftermarket is disconnected/pull the fuse for - anything like aftermarket stereo, subs, amps, nav, alarm, remote start, seat heaters, trailer brake/light setup, etc.. anything like that, their wiring harnesses need to be disconnected/pull the fuses for it before you try to tune anything...  -----   The issue is that aftermarket stuff like that taps into the ignition wires for power, and that interferes with the communication from the programmer to the PCM and you will get errors... 

also make sure everything is turned off inside the truck.. lights, radio, heat/fan/blower, do not operate power windows, put your parking brake on, all doors closed, etc...
Have to have the key turned to ON position, but engine not started/running...  

Also, if you have low voltage like from a weak battery in the truck, that can also cause tune install issues.. so make sure your truck battery is fully charged...
