I am doing a project and need .dbc file with cell pair voltages to work my battery testing equipment. I have seen on Github for Nissan leaf .dbc file and didn't find any file with code corresponding to cell pair voltages.
I am curious to know why none of them contain code related to cell pair voltages? I find .dbc files with other parameters and would like to know how people generated them. Is there a way to generate our own .dbc file with messages and signals of ones choice
