Sensor grounds and the 5v reference circuit (a 2016 ScannerDanner Premium video)
Some standard no start procedures that can be followed for any car. It is amazing that the principles we follow on this 1992 Ford Taurus, are the same ones we can follow on a 2018 model from any manufacturer.
This is a ScannerDanner Premium video from 2016 and is being uploaded here to YouTube to help out a subscriber. ScannerDanner Premium is now available from my website here

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!
