It is an electronic control unit (ECU) within the high-voltage battery system of BMW's electric and hybrid vehicles. Its primary function is to manage and monitor the battery's health, including temperature, charge, and power. In the event of a crash, the system triggers safety measures, including blowing pyrofuses in the SME module to disconnect power and prevent further damage. Common issues and solutions Crash data: After a collision, crash data is stored in the SME, which prevents the vehicle from starting. Reset service: Many specialized repair services can reset the crash data and replace the blown pyrofuses in the module, restoring it to its pre-accident condition. You would typically remove the module and send it to the company for repair. Module replacement: A new SME module can be purchased and installed, but it will require programming to the vehicle. This can be a more expensive option than a repair service.
