Saw this on the OVMS docs: https://docs.openvehicles.com/en/latest ... index.html
Assistance is appreciated as I haven’t had time to try to override the TCU using the OVMS or find an alternative solution to prevent the TCU overriding the messages while still allowing the hands free microphone to work.
Has this been addressed by anyone yet? Not sure I fully understand the issue.
Not adressed yet. AFAIK unplugging the TCU fixes so that OVMS can function and send heating requests, but the downside is thet the hands free microphone stops working.

I've been working for over 10+ hours with the CAN database files. I recently stumbled upon new information, and can finally solve 60% of the EV-CAN with this information. I am uploading all my findings to GitHub, so anyone wanting to take it into use will have an excellent starting point.

Database files can be found here: https://github.com/dalathegreat/leaf_can_bus_messages


Hi, Dala.
Your work is excellent! Won't you mind if i will use your DBC file in free CAN bus cloud decoder? Website is can2sky.com
Everybody can upload raw CAN bus log (several formats are supported) and see all decoded parameters in readable form, built plots.
Also there are some tools to investigate unknown parameters.

Some screenshots:

The values are correct, but when you see a sawtooth like that it is due to the data being multiplexed. That location contains several datapoints, and another part of the message defines that. The "LB_Historical_Data_Swich_Flag" is the multiplex in that message.
