Ask HN: Database of writable CAN bus data for cars

by fndksksvdk on 10/13/23, 3:10 PM with 1 comments

Does anyone know of a source for what data is exposed over the CAN bus in any cars?

Specifically, I'd like to be able to write data over CAN to control non-critical features (radio volume, windows, climate control, etc.).

Is my only option to use a sniffer while pressing steering wheel volume buttons?

    Hack a Tier1 ;)... Start a workshop and get tester access? Look into the comma ai pile of stuff they gathered?
