Following. My ECM apparently just gave out randomly. I've been starting every few weeks for a minute just to keep things fresh. Go out one day and nothing. TIM wont recognize the ECM. It will recognize all of the other modules. Tested the 70 pin connector and i have power at pins 52 and 53 and grounds at 65 and 66. Took the ECM to a local truck shop that has Cat ET and he couldn't get any communication. Not a very tactical situation for a tactical vehicle.
