Advanced System Testing Strategies

This course, Advanced System Testing Strategies, brings the experience and expertise of ASE Master Technician John Forro to an analytical approach to vehicle diagnostics. There are many pathways a technician can take to repair a vehicle, and the information presented in this class will help them determine which is the best, quickest, and most profitable direction to take. Discussions will cover the six main inputs of vehicle diagnostics: temperature, pre-and-post-O2 sensors, load sensors, demand sensors, RPM, and fuel trims, and how each path will give you results. The instructor will assist in not only gathering data but how to best interpret it. John will show how a real-world vehicle problem was assessed through multiple case studies, pathway determined, and the solution reached. The course also covers recommended practices when using pressure transducers, scan tools, and labscopes. Data Bus communications are also discussed.
