cabana

cabana is a tool developed to view raw CAN data. One use for this is creating and editing CAN Dictionaries (DBC files), and the tool provides direct integration with commaai/opendbc (a collection of DBC files), allowing you to load the DBC files direct from source, and save to your fork.

Reverse Engineering Your Car

One big purpose of cabana is to discover new CAN messages and signals.

A good way to go about this is to use the can_bit_transition.py script in the panda repo. The idea with this script is that, provided logs downloaded from cabana, you can quickly locate a specific bit flip.
