I do actually have some theories on this, but I'd like to play first.Is there a way to figure out battery degradation from PID codes?
The battery impedance and resistance are apparently available, but not in my PID list yet. I'm hoping that either working with some more expensive tools, or waiting for the service manual to come out (next week?) will let us know those details.
However, there may be an easier way. Let me crunch some log files and see.
