I have an EQS W297. After the battery was discharged, the car did not start and a fault code appeared in the BMS. The Fusi-Lock function is activated P1C80FA. If anyone can help fix it, I will pay.
 
Read EEPROM and send.
 
Try resetting the BMS module.
 
The contactor was actually welded. I changed it, but Fusi-Lock doesn't help. The contactor status shows that the pre-charge and positive contact are still stuck in the closed position, but in fact this is not the case. Maybe I need to replace the slave modules that connect via fiber optics to the BMS?

Send the VIN number of the car.
 
For Fusi-Lock, you need to submit a report to MB. Once the report is approved, perform an online reset. Or replace the BMS.

My problem was solved by modifying the EEPROM in the BMS slave modules inside the battery.
