LeftieBiker said:I should caution that Nissan is still only obligated, AFAIK, to replace the bad cell, not the whole pack. They usually replace the whole pack, but not always. If the #1 cell is easily accessible, they may opt to just replace that one...

As the others have said, it will take some tricky work to get it to DTC on that cell (safely so you don't lose power down the middle of the highway in traffic for example), but as always we find a way here... :lol:
It doesn't work that way. At high SoC the available pack voltage has only dropped 100 mV.knightmb said:Still showing 54.2 kWh of capacity also, which is still good given the lower SOH, I would imagine that if Cell #1 was behaving properly, you could easily get it back up into the +56 kWh range of capacity for a full charge.

At low SoC, all the good cells are unable to discharge to the normal threshold for low cell voltage because the bad cell has invoked turtle mode. The tell tale sign of a pack with a weak cell is normal range estimate at high SoC, but in practice that range is not close to realistic even with EPA type driving
To my knowledge, Nissan has never disclosed the conditions that set a DTC when weak cell(s) are present, although past threads make it clear that Nissan has no interest in having the warranty invoked when an old pack has multiple weak cells. In this case ONE cell is weak, which is presumably what the algorithm is looking for. The greater the discrepancy between one weak cell and the average of the rest of the pack, the more aberrant the pack. This is why stomping on the go pedal when the pack is cold will likely unmask the weak cell, and perhaps cross the threshold to set a DTC
