Changing the main battery pack in a Nissan Leaf to another one results in the error code P3102, which cause turtle mode with reduced engine power (limp-mode). The file generated will remove the P3102 code and allow for changing main batteries. Note that this is only for direct swaps(ZE0 24->ZE0 24 or AZE0 30->AZE0 30kWh), not for battery upgrades(ZE0 24->AZE0 30kWh or ZE0 24->AZE0 24kWh)
This script has been confirmed to work with the following vehicles:
- Nissan Leaf (2011-2017) ZE0 and AZE0
- Nissan e-nv200 (2014-2017)
