Warning
Cybertruck electronics are powered by a 48V "mid voltage" or "MV" architecture that is designed to improve efficiency. Servicing MV components requires extra knowledge and care in order to avoid personal and/or vehicular harm. Read and understand MV precautions in Electrical Precautions and make sure any required MV-related training courses have been completed, as applicable.
