New Training for 2022



In this hands on workshop, students will learn diagnostic and repair techniques for working with high-voltage vehicles.

The course covers the components that make these vehicles unique and delves deep into their operation, their specialized components and effective diagnostic procedures. It also extensively covers the most critical subject of the lessons: safety. This class explains the vehicle’s workings, preparing the vehicle for safe diagnostic interaction, proper personal protective equipment for the technician, and recommended tools.

Topics include: Electricity fundamentals and testing procedures, wiring schematics, hybrid/EV configurations and components, safety, regenerative braking, EV cooling systems, scan tool diagnostics and much more.


  • Understand the fundamental theories of electricity and electrical current

  • Communicate on how to test electric circuits

  • Generalize the different types of electric and hybrid electric vehicles

  • Understand personal protective equipment and the procedures to follow



  • Describe electric vehicle diagnostic procedures

  • Communicate on high voltage battery technology and components

  • Describe high voltage component testing, removal, and replacement

  • Illustrate hybrid and electric vehicle maintenance procedures

Already Know the Basics? Take On Level 2 Training.

Our new level 2 class picks up where the level 1 class left off!


  • How does the HV system power up and why does it power up this way?

  • Complete disassembly of inverter/converters with an explanation of the components and how to test them.

  • Complete disassembly of the high voltage battery pack with explanations of components and what they do and how to test them

  • We will also perform motor-generator testing with meters and scopes and cover in-depth scan tool PID diagnostics!

I thought it was very well done. John Forro, the instructor was very, very informative, very learned on the technology. This is very cutting edge. He cut this car up to allow everybody to view the process, the inner workings. He showed us all the safety concerns. Very, very thorough on testing procedures. We were very, very pleased. We've got 20 people here, and every one of them is just thrilled that you guys could do this. And we really appreciate it. Very good job. Greg Kaufeld
