The objectives of this class:
1. To quickly and accurately verify input sensor wiring for opens and shorts.
2. To be able to identify the circuit design, and circuit wiring, without a wiring diagram or service information.
3. To prevent the need to access the computer, and unplug it, to perform manufacturer recommended wiring and circuit tests.

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!
