HV Contactor Voltage Negative

[N1naz]

Hi All, Wondering what might be up with this. When vehicle off Car scanner shows 655.35v for the "Hv Contactor V Negative" when on it shows .96V See photos. Is 655.35v Normal?? Has anyone else seen this? No Error codes in OBD or displayed errors shown in car. Possible Car scanner or OBD dongle issue?

655.35V is the maximum value for a 16-bit unsigned integer, scaled to 0.01V.

65535 = 2^16 - 1

Basically because the car is off and there’s no data, the parameter defaults to the maximum possible value. It’s not really 600V.
