Hi @Tom-evnut - sorry to post this as an issue but I'm not sure where else to ask the question. I'm working on a system to read the BMS from the Tesla modules and was hoping to use the over / under voltage detection on the Tesla BMS as a backup (i.e. if my BMS failed, then this would trigger and potentially open a contactor).
I've managed to get the fault status working in terms of there being faults in the appropriate registers, however that line (on pins 6 and 10) never seems to go high. I've pulled it up with a 4.7k resistor, and when the BMS board is powered off it's high, but when the power's on it gets pulled low and kept there regardless of any fault conditions.

Did you ever see this line go high?
