Gary, was the module replaced at the dealership or did they have to ship the Leaf (or the battery pack) to a specialized tech center?garygid wrote:They replaced Module 35 (cell-pair 69 and 70) because 69 was
apparently not doing what it should be doing.

Dave, I remember reading here or on the Tesla forum that Kevin Sharpe had a similar experience with his Roadster. Presumably, the issue was detected remotely with the help of the data the car transmits over the air. I won't want to speculate too much, but it might be worth asking how Tesla does it, and direct the same questions at Nissan. Based on the number of pages reserved for module replacements in the service manual, one could see that Nissan anticipates this type of service to be fairly commonplace. We had a discussion about this last summer at a BayLEAF meeting, and it was assumed then that the pack would have to be shipped to a specialized tech center. This is the case with the ActiveE for instance, but it's a small fleet compared to the number of Leafs in the field.DaveinOlyWA wrote:would be nice to find out how the issue was discovered. what was time frame from when you had your battery check and the notification you had a problem?

The dealer called about Nissan wanting to see the LEAF within
the week after the annual Battery Pack check was done.
Although it could be the car "ratting itself out", the timing makes
that appear to be a bit suspect.
It is, but I'd feel better if the techs at the dealership (and eventually my independent mechanic) were able to see these problems for themselves. For now, these failures are new enough that Nissan's engineers are likely keeping tabs. Later on? Who knows.91040 wrote:It is great that Nissan is being proactive about this!
that will happen. this incident here if it repeats itself will be written into an update that Leaf techs will need to know. the automotive industry is fairly proactive in providing a lot of updated info to its employees but it is usually up to the individual to get that info and retain it and that is not an easy thing to do especially when the volume of new information is most likely substantialdavewill wrote:It is, but I'd feel better if the techs at the dealership (and eventually my independent mechanic) were able to see these problems for themselves.
