    Perhaps in the year 2050 OBD3 data readers over BT8 are built in and everyone can read them with their phones. Go EU go… :)

    (Just wanted to mention that the amount of Sensors/PIDs available in Car Scanner PRO with the G3 profile is absurdly high. The page never stops scrolling, it’s info overkill. :)

    I now also have a Gen3 PHEV 2014, aswell as two Gen2. Fascinating cars indeed. :giggle:

    Does the Carscanner free version suppose to read Electric Water pump rpm?
    Mine is not showing anything and want to be sure if it means fault. Prius 2010 Gen3 with Carista OBD

    On a side note, I asked the Car Scanner developer a question about whether it works with CarPlay (it does) and he got back to me the next day. Same with the OBD Fusion app developer, which also works with CarPlay.

    Car scanner on gen3 does not work properly on water pump rpm. I have notified the developer several times and he claims it does. Testing is clearly an issue. They do have a point editor in the latest version but I have not tried it.

    I use two other higher dollar scanners when necessary. Car Scanner excels as an easy to use phone app with better graphics configurability than my other more elaborate scanners.

    Its interface is stored in the glovebox and ready to go for codes and most gen3 hybrid data. Of all data, coolant temps are essential which I monitor fulltime with a P10 obd2 display. That device also has early warning audible alarms setup for coolant among other things.

    I see, because it seems it sees the inverter water pump RPM but not the combustion engine water pump RPM. I will also submit request to the DEV

    The inverter rpm does not change in realtime using car scanner. The best test for either is bidirectional control followed by rpm. With coolant temp as priority. Don't run with high coolant temp especially if flashing your light.
