I think I found the problem on WIKI service builtin. Does anyone know how to resolve this or know of someone that might?
Service Req'd B6 when plugging-in AC in Park Mode: Erroneous BMS firmware programming when doing batch upload.
The BMS PCB did not notice when the VCU F130 processor reset, therefore it did not know to reset itself. Reworked VCU firmware to cycle power on the BMS enable line, and changed the BMS to notice this change on the enable line, as short as 20 msec.
