How do you really reset the computer in your truck? Why is this such a mystery and why can’t you locate proper procedures from Chevrolet on this. Well, today I give you my personal experience on resetting the ECM/PCM in my 2020 Chevy Silverado Trail Boss. I found the problem with the KINGBOLEN YA200 OBD2 Port Scanner and I will leave a link below. I am really glad I was able to use this in order to help me find out that I had a communication error. The error was code U0100: Lost Communication With ECM/PCM A. I took my truck to a shop for them to reset my truck’s computer. After the Computer was reset, I did also have to do a throttle body relearn procedure. My Auto Stop/Start was not working before the ECM/PCM computer reset and then it started working again.
