I just finished the very first lesson tonight. I am blown away by how much I was able to learn in just one session. In my years at dealerships, training courses and on the job training situations, I have never had this explained to me so simply and been able to retain so much. 100% worth the money, thank you scanner danner for allowing me to take my skills as a true diagnostic technician took the next level!

Hola , me gustaría agradecer las contribuciónes que ha hecho Paul Danner a esta industria y sobre todo a mi capacitación con sus clases en YouTube y ahora que por fin pude hacer llegar su libro a México , e podido tener un refuerzo de lo aprendido y me a inspirado a adquirir hace 6 años mi primer ociloscopio y ahora que tengo ese conocimiento me a ayudado a dar el siguiente paso con la adquisición de un picoscope y hacer crecer el negocio familiar en el área de diagnóstico automotriz

Paul Danner is an indispensable part of the diagnostic community. His diagnostic approach and teaching style has single handedly improved my day to day diagnostic abilities. Before I found his youtube channel 5 years ago, I was feeling overwhelmed by the complexity of some of the circuits involved on these modern vehicles. His approach to basic electrical building blocks reply can accelerate your understanding of these circuits quickly. I have a very good fundamental understanding of what it takes to troubleshoot and reverse these circuits now because of him and his class. Why spend hours digging through flow charts to end up at the last step of Replace Computer with KNOWN good part.. really.. that's not productive. Once you master his teachings you will be equipped to come up with your own test to narrow down diagnostic possibilities to a minimum quicker and more efficient than the people who built these components. Why waste time accessing a module hidden behind the dash, when your testing methods can prove wiring integrity to and from the module to the component based on your fundamentals! Don't hesitate to invest in this program, trust the process and see the results!

An awesome book on driveabilty daignostics and computer systems troubleshooting. A must have for all auto techs. I'm a disabled former Auto tech . I still use it to this day.

Having been in the auto repair industry since 1982 and I also am ase certified, I have had my fair share of problem vehicles to try to figure out. I wish I had the vast knowledge that scanner danner demonstrates on his videos and in his book back when I began this journey. Many kudos to you sir for sharing with us and educating new and old technicians alike. I really enjoy your videos and learn something new from most all of them and from your book. Keep up the great job you are doing.
