Everything was working normally, and they bang, the IMA light came on, and the car still had assist and regen as normal. A reset cleared the IMA light, but as soon as the car was started it came back.
The first code was a 1449, after clearing, I got a 1447, and it remains as a 1447.
Can't wait to get it on the bench and see what I find.
Replacement pack:
I am watching the 60K replacement pack leakage current as it just sits after a full charge to see how well balanced from the self discharge aspect it is, and hope to get the smart discharge monitor and overnight two stage charger finished so I can give the whole pack a couple of cycles before I swap.
I made some progress yesterday on both the two stage charger and discharge monitor, but still have some work to do.
