Wiring diagrams are road maps for vehicle electrical systems. Do you fully understand them, or do you just follow the lines from one box to another? Join Dorman Training Center instructor Pete Meier and learn how to incorporate the wiring diagram into your diagnostic process to solve electrical faults more efficiently.

This two-hour webinar provides useful diagnostic information for technicians of all skill levels. After an overview of vehicle computer system operation, you’ll see examples and case studies to build your comprehension of scan tool usage, PIDS, bi-directional control, fuel trim adjustments, MAP/MAF/O2 sensors and air-fuel ratios.

In this webinar, Dorman instructor Pete Meier will share the top 10 DTCs technicians face on a daily basis, and provide tips and techniques to help you quickly and correctly isolate the cause and repair the concern. If your repair doesn’t meet the ECM’s test requirements, you’re just setting yourself up for a comeback!
