    Codes tested on torque app 1.8.22 should be good for all versions.

    Note prius hv cooling fan is variable speed.
    Hv cooling fan gets one extra volt of electricity per 10 mph road speed increase (approximate).
    Setting cooling fan speed via scanguage or torque app puts a fixed non-variable voltage on the blower motor.

    A scan/torq setting of 3 provides excellant battery cooling up to a road speed of approximately 45 mph.
    This setting of 3 inhibbits the fan speed at road speeds above 45mph.
    Better said normal prius fan cooling control (variable speed) runs blower faster at 45mph than the scan/torq setting of 3.

    But normal prius fan control tries to run hv blower (stealth mode unheard by driver) just below road noise and undetectable.

    Thus batteries get cooled best at hiway speeds under normal prius variable blower control.
    Or cooled very well with scan/torq setting 4 (fixed voltage) up to road speeds around 60 mph.

    I will try and upload usbseawolf's extended pid file that has the hv blower control codes added.
    The attached/uploaded file name will end with .txt extension. Just rename file so it ends with .csv
