Battery Pairing - Testers wanted

Tue Jun 02, 2020 4:56 am

So I thought I would dump this valuable information freely https://github.com/dalathegreat/Nissan- ... eryPairing

This should remove the P3102 code that manifests itself when you swap main batteries between Leafs. I do need some brave testers for this, so if you are doing a ZE0 24->24kWh, feel free to test this and report back :)

One person tried this! And wasn't succesful. Seems like we are missing some seed-key/rolling code in the demand messages. Maybe someone knows more about this here? https://github.com/dalathegreat/Nissan- ... t-40628187

Simply amazing work Dala. I have a feeling many folks will find this essential information to complete a DIY battery swap!

Integrating into Leaf Spy Pro is icing on the cake :-)

We almost have it! I've been helping Jim to test this out on all generations of the LEAF and env200, and we are so close to calling it done.

So does that mean the other products out there that do this (non-Nissan I mean) are doing the same thing or do they figure out something different? :D

Great work BTW, look forward to a Leaf Spy Pro update to fix some nagging bugs with the Gen 2 Leaf :mrgreen:
2020 Leaf SL Plus - (Manufacture Date March 2020)
2018 Leaf SL - (Manufacture Date February 2018)
2013 Leaf SV - (8 faithful years of service before trade in at 75,679 miles)
