Hello!
VOLVO XC90 2023
MVBM 32371368
I have problem with clear crash in this module.
The crash seems to clear, but when clearing errors I get the failed message. Of course, when reading again, the crash occurs.

Charge the MVBM to 48V and make sure all cells are equal.
If that doesn't help, you need to read the MCU.
