    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.

    Hi, new member here with a 2013 85P I rebuilt 40k miles ago now went dark. I suspect it is a contractor. Need guidance on BMS reset and tool availability. Any help would be appreciated, thanks.
