This is an evolution of the spreadsheet found at https://docs.google.com/spreadsheets/d/1EHa4R85BttuY4JZ-EnssH4YZddpsDVu6rUFm0P7ouwg/edit#gid=1
Proper CAN database files are also found in this repository along with the original excel spreadsheet. The .dbc files are easier to use when working with CAN messages. Please note that there are major differences between ZE0,AZEO and ZE1 LEAFs
Please fork the repo and make changes in your repo before creating a pullrequest, or message me if you have some CAN findings to share.

With this tool you can open the .DBC files and explore the frames and the position of the data inside the frame.
DBC files are also extremely useful for reverse engineering, if you playback a CAN log these files can be used directly for translating the data.
Nissan places a few error checking methods into the communication. This video explains the functions of these:
Actively asking the different control units for info is another thing. The database files here won't help you (those are for passive listening), but here is a list of the different control units query and response IDs. Please note that the availability of the control modules varies depending on model year (Only ZE0 has 'Shift' module for instance)
| Control Unit | ID Query | ID Response |

| Consult3+ | 0x7D2 | |
| VCM | 0x797 | 0x79A |
| BCM | 0x745 | 0x765 |
| ABS | 0x740 | 0x760 |
| LBC(BMS) | 0x79B | 0x7BB |
| INVERTER/MC | 0x784 | 0x78C |
| M&A (Meter) | 0x743 | 0x763 |

Here's an example of a request, checking which gear is selected from the VCM:
Description: Gear position (1=Park, 2=Reverse, 3=Neutral, 4=Drive, 7=Eco). The fifth reply byte value is the gear value. In the example gear is 1.
