    i was checking some of the readings on the torque pro app
    i couldnt figure out what the issue is

    some of the read out :
    Auxilary battery temp : -41.8F
    auxilary battery : -24.3v (Highest value22.5 lowest value 24.1)
    ambient temp :42F
    delta SOC :0.0
    hv chrg ctrl: -24kw (highest value: -3.5 lowest value: -24)
    coolant temp:132.8 (highest value: 141.8 lowest value -41.8)

    do i need a new 12v battery or maybe something else?

    Coolant temps are in Fahrenheit? Must be. Still, lowest value -41.8? And highest value oddly similar. Maybe baked-in range limits?

    What does a multimeter voltage test of 12 volt battery say (first thing in morning, car off)?

    I get some strange readings using Car Scanner -> All Sensors too and just ignore them util I know if they are too far off.
    I do get the exact same temp -41 F for the aux battery temp in Car Scanner. and it doesn't matter what time of year it is either.

    You must be setup for the wrong car or wrong units

    Aux Battery Temp is at the Very bottom ( absolute last entry ) of Car Scanner -> All Sensors for my Gen 4 Prime.
    sorry if that was not clear in my post.
