John Forro outlines how Autel’s diagnostic tools and EV software help guide technicians through high-voltage safety procedures.

Autel Academy Technical Trainer John Forro explains the key service differences between electric vehicles (EV) and traditional internal combustion vehicles and what those changes mean for technicians.

He discusses how EV weight, cooling systems, tire wear and brake service create new maintenance considerations, even as EVs reduce some routine service needs.

Forro also outlines how Autel’s diagnostic tools and EV software help guide technicians through high-voltage safety procedures, component testing and battery system diagnostics, while training resources and software updates help shops build confidence as they begin servicing electric vehicles.
