Diablo Trinity "Unable to communicate with ECM"

Post by jjc_003 »

I have a 2007 classic GMC Sierra 2500 with Duramax. I backed out of my tune to "update" my trinity so I followed the "restore factory tune" instructions as I always have BUT I am now getting a "Unable to communicate with ECM" error code on the trinity. I can't even start my truck now!!!
HELP needed ASAP!

Thanks in advance for your help and support!

if it wont start, something more must have happened, do you recall if it failed somewhere?

Please give us a call with the tool powered up inthe truck.

Thanks for the help. I eneded up having it towed to the dealership. They re-flashed the stock programming in the truck and now the Trinity needs to go back since the screen is broken (thanks to someone shoving it in her purse!!)

Thanks again guys love the product!
