hello, I don't know much about the subject, but I heard that there were cases where if the battery is empty, the car won't start until you change it.

You must replace unit battrey control that installed on hybrid battrey pack.
this unit sense voltage battrey cells of battrey pack(28 cell) and send it to hybrid ecu
