OBD2 software that shows the Hybrid battery status?
Is there OBD2 software that can read the status of the high voltage battery?
I do have software that shows me the 12V battery status, but can't find software for the hybrid battery.
I know Toyota/Lexus can check the health of the HV battery, but i want to monitor it myself.

Yes you can, the big orange wires are high voltage.
But... I want to see the voltage of the individual 7.2 volt packs.
These 40 packs are controlled or checked by the battery ecu. If one of these fails (has a lower voltage than the rest) the total battery is dead and you get the "Check Hybrid" error.
It's like a chain, if one link fails the entire chain is broken.
So checking 288Volt in total doesn't show if one pack is going bad.
But the good news is, my hybrid system is working fine as far as i can tell. And it should last many more years.

ive plugged in my OBD2 tool and the main ECU is unaware of the hybrid system it seems like.
The ECU treats it like a turbo, where it uses boost upon throttle pressure and load %.
I was amazed at this its so ingenious. When the vacuum guage goes over in to the + i can see on the screen the energy to hybrid motor is supplying power to the wheels.
There should be another inspection/diag cable somewhere in the hybrid motor/system to check the status, im very interested to know where if anyone could shed some light.

i have a scangauge II that shows prius data such as battery voltage, temp, amp discharge rate, state of charge and a whole wack of things you can show
the problem is... finding the right codes to input the scangauge II to read them in the first place. that takes someone quite talented to do that for us :P
