[weavetr2000]

hello!
so i have a 2015 ed and bought and received the ecm today. Im on a stretch being the weekend for help. I installed the tune and the truck read off serveral messages. air ride system needs service. trailer brake needs service, radio locked out, airbag sys needs service. and the worst part the truck fired up and instant died 3 times, and now wont start. i put the stock ecm back in and radio is still locked out and airbag light is still on......any Ideas!!! I already emailed gde but like I said its Friday night on the west coast here.

Check the wiring harness connectors and make sure it's clamped in place.

Welcome! Like mentioned, it sounds like the ECM connections isn't seated correctly. I would unplug it again and be sure nothing is bent up and everything lines up properly.

Otherwise, it could be a faulty ECM/Tune. It's possible!

so an update, removed the negative and positive battery cables, zip tied the cables together and stepped on brake peddle. reconnected the battery radio works, air bag light is off, all operating normal now with stock ecm. thought Id give it a try and reinstall gde ecm with the same process and still had the same results as last time with the gde ecm. reinstalled stock ecm and battery process.....all lights off good to go. Im working with support for gde. thanks you all for the possible quick fixes. will up date.
