How old is your car? Newer batteries don’t seem to be lasting that long, what’s the voltage?

Also, which module is producing the error? I always get a “supply voltage too low” code from the headlight modules but they work fine. I think it’s simply because OBDeleven is doing the scan with the engine off.

Yep that’s the code I get too. I bet if you had the engine running, that error would not appear. I wouldn’t be worried about it though. My theory is it’s because OBDeleven forces the lights to do the self-adjust procedure when it first connects to the module. If the engine is off then the voltage is lower and the lights complain about this.
