    Would anyone happen to know what the letters GIVA, GIVB, GIWA, GINV, GIWB stand for on the wiring of the HV Control ECU Connector and the inverter connector?

    Aren't they just the names given to pins 2, 3, 18, 16 and 19 on the I-10 connector and pins 34, 33, 32, 23 and 31 on the H-15 connector?

    The V/W in the name most likely relate to the generator phase V/W current respectively.

    I finally wrapped my head around that diagram. Everything on the volts and ohms test(s) check out. Looks as though the inverter converter has gone bad.
