Tesla Model S BMS latched! Reset? eeprom

This site may earn commission on affiliate links.
My BMS of a 2015 Tesla Model S (P85D) is latched.

Diagnostic result:

BMS_w023_SW_Contactors_Open_HWOC
BMS_w026_SW_Ctrs_Disabled
BMS_w086_SW_Not_OK_To_Precharge (hidden)
BMS_f086_SW_Not_Ok_To_Precharge
(BMS_a086_reasonForNotPrechg)

The pack ID is 57 /49
maybe someone has "clean" eeproms or can reset it?

I hope someone can help.

Thanks.
