    Morning guys. I'm done with replacing some of the bad battery modules, on this Prius. We actually replaced about 7modules.
    Cleared the stored codes, but the P3000-123 keeps coming back.
    Alldata points me to check
    *HV battery system
    *Battery ECU

    **I have swapped a known good battery to see what the problem was, but it just did not work.
    ***could the problem be in the HV wiring harness?

    Anyone with an idea, pls he'll!!!!!

    are you running the car with the heat or ac on? that would cause the ICE to run a lot more especially when the car is not moving. try to warm the car up by driving for 5 miles, reset the mpg display and drive on cruise control at 65mph on the highway for 30 miles and see what you get.
