I've ignored this DTC for a long time because even if I cleared it, it came right back but didn't appear to affect anything in the vehicle. I did read up on what it was suppose to mean but not being a professional Leaf tech, not really sure what I should do or not do. Anyone else here with more knowledge, your wisdom would be greatly appreciated!
