    Hi mates. New here...
    Well i bought a 2007 prius...
    I knew it have a problem but it has only 100.000 km and the egine is very good.
    Well a little before i take it the batteries showed the triangle. But now the ventilator for the cooling system of the batteries work all the time i drive.
    Well. I also bought the OBDII for chech witch modules need replacement. (i found all them out at internet).
    I tried the Torque app and also one more... Both give me many info from the car. I don't know why but it doesn't inform me about the volts of the modules, non of both apps.
    Anyone kmows whats that means? What i have to do next? Any solution other than to go to Toyota?

    Welcome to PriusChat!!
    Sounds like the HV battery is failing.
    Do you have a multimeter, or a volt meter?
    Go online and buy a 'mini-vci' cable, costs about u$20. You can use it with Techstream, same software toyota uses.
    Since the cooling system for the HV battery is running all the time, have you had a chance to at least clean the HV battery fan?

    If you haven't tried Dr. Prius or Hybrid Assistant, you may want to try them. The version of Torque Pro that I have required a separate download of Prius specific information (called PIDs) in order to get block specific information. See below:

    [Edit] @SFO, I now see you have already included that link in your signature.
