It is no secret that vehicles are practically littered with control modules. These modules create a lot of amazing features in our vehicles. As a technician, the day will quickly come that we must diagnose and replace one of these modules. This video highlights the diagnostic path to replacement and programming of a radio module in a 2018 Chevrolet Volt using the GM GDS & SPS factory scan tool software.

Have you ever done anything with a GM HMI Module in a 2019 C7 corvette? I have questions..lol
You need to download the GM bus viewer , it works through the MDI-2 and allows you to in a sense scope the networks.. obviously it’s not as fast as a scope but it’s very helpful .
THANK YOU FOR YOUR TIME… WHY ARE THERE NOT MORE DIAGNOSTIC VIDEOS?
