Alphardhybrid

Long story short Bought a alphard hybrid 05 for project car First scan, p3140, c1310, p1259 Solve p3140, someone opened inverter over and unplug service plug switch connector Clear the code , and then become p3000 spend sometimes eventually found out block 10 voltage only got 3-7 v , but those cell are good and realise might be service plug big fuse gone ,( but weird, i can measure whole battery 22x V, but block 10 low voltage. try to use jumper leads short 2 cell, bring block 10 to 15v , clear code, now p3000 gone Try to start go into ready mode, but nothing happen scan again got p3004….. anyone got idea what should i do next step? is it bad HV battery ECU? or even inverter? when i try to start, i can hear HV battery contactor click, but system seems refuse to go into ready mode
