What does BMS_f033 mean?

Tesla fault code in the Battery Management System (BMS) module. The Battery Management System (BMS) will trigger this alert when it senses a loss of contactor power while the contactors are closed. The BMS assumes that it could be because the pyro fuse on the contactor power supply signal blew during a crash. This may trigger while a vehicle is in Service and the contactor power supply loop has been pulled.
