This is a preview I put together of my Chapter 7 lectures available on ScannerDanner Premium. For anyone interested in joining my class at Rosedale Technical College, but cannot be there in person, I’ve created this channel for you. There is a 14-day free trial period so you will have plenty of time to review the content before making any financial commitment. On SD Premium you’ll find daily lectures that go hand-in-hand with my book (Engine Performance Diagnostics), playlists that mirror my class format, as well as exclusive case studies. Head over to ScannerDanner Premium for more information: https://www.youtube.com/channel/UCs2NZ_wQFDFvV0QOhoZgASA

Want even more diagnostic training? Whether you are a DIY trying to fix your own car, someone looking to become an auto technician, or a current auto technician that wants to get more into diagnostics, subscribe to ScannerDanner Premium. There is a 14 day free trial.

On ScannerDanner Premium I will bring you right into my classroom at Rosedale Technical College. You will find page for page lectures taken right from my book as well as exclusive classroom type case studies. What is so special about these classroom case studies? I pull live problem vehicles directly into my classroom and we troubleshoot them in real time, using and applying the theory and testing procedures we learn during the classroom lectures. There is no better on-line training of how to troubleshoot automotive electrical and electronics systems anywhere!
