This case study is a good example of how my engine performance testing methods can easily be applied to other areas of the car, giving you confidence during diagnostics! This Chrysler 300 comes equipped with ‘digital’ ABS wheel speed sensors, which differ from conventional variable reluctance sensors, and are becoming more and more common on newer vehicles. Be sure to check the related videos below for more ABS sensor testing info.

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!
