This immersive three-day, in-person course trains up to six technicians in the safe disassembly, diagnostics, and reassembly of Tesla Large Drive Units (LDUs). Developed in consultation with the EV Clinic, the curriculum blends classroom instruction with guided hands-on practice. Technicians will learn the fundamentals of electrified powertrains, identify common Tesla LDU failures, and apply troubleshooting and software diagnostic techniques using real-world tools. Throughout the course, participants will complete a full teardown and rebuild of a Tesla drive unit.
