    Battery voltage is 13.2 (it is on a charger). If not low 12v battery, what can it be? I pressed the blue splat and got data that i don't know how to interpret. IMG_20250814_163430Z.jpg

    In that data you can interpret. You see about 4 lines down battery volt value 7.4 or some nonsense . That's part of it . You reading 12 plus but the car is seeing 7 volts of what you see.. problematic . Wer other voltage disappearing to?

    Techstream. Blue splat = snowflake- get more data on the code. The 12v batt tests good with a load tester.
    I saw that 7.4 and I don't understand what could cause that.
