I'm using multi-program.
However, the pinouts for multi-program are different.
Is there a way?

Olá, para resolver o problema da bateria de 48V após uma colisão, você precisa resetar os dados de acidente (crash data) no módulo BMS.

Você pode baixar os arquivos necessários clicando no botão de download no topo desta página (Resource). O procedimento geralmente envolve:
  • Conectar um programador (como VVDI Multi-Prog ou similar) ao chip do BMS (ex: FS32K148).
  • Seguir o pinout fornecido nos arquivos.
  • Gravar o arquivo limpo/resetado.

Boa sorte com o reparo!

Hello,

For the BMW 48V (mild hybrid) LG battery crash data reset, you typically need to work with the flash memory of the BMS controller. Here's what you need to know:

What needs to be addressed:

  • Flash memory – This is where the crash data flag is stored. You need to read, clean/reset the crash data, and rewrite it.
  • EEPROM – In most cases for the LG variant, the EEPROM also stores fault counters and crash-related flags, so it may need to be cleared as well depending on the specific case.

To help you more precisely, I need some details:

  • What is the ECU-UID / part number on the battery label?
  • What MCU/processor is on the BMS board? (e.g., Renesas RH850, NXP S32K, etc.)
  • What read/write tool are you using? (VVDI Prog, Multi-Prog, JTAG, BDM, etc.)
  • Did you already open the battery and identify the BMS board?
  • Is the battery completely dead/locked or does it still communicate via OBD?

The LG variant can differ from the A123 variant (like the one shown in the original post) in terms of BMS hardware and reset procedure. Providing the above info will help determine exactly which memories need to be touched and whether a clean file or just specific byte editing is required.
