Tesla 16V low-voltage Li-ion battery - BMS repair from the MM9Z1J638 EEPROM dump (4096 bytes). Upload the original dump. You get the repaired file and the code stored in the dump: it must match the code on the battery label, character for character. If any character differs, do not write the file (the read is wrong or the dump belongs to another battery). After writing: reconnect the BMS connector and run the activation procedure. Safety: trained technicians only. Charge at the BMS board with a current-limited supply (at least 15.5 V) before reading.
