Exploring a Car’s CAN Bus Data

If you’re the scientifically and technologically curious type and don’t know about Ben Krasnow’s Applied Science YouTube channel, you are in for a real treat. The brilliant, ever-patient, always methodical Ben experiments with chemistry, physics, electronics, and electromechanical systems, always with real-world applications in mind. He has built a basement electron microscope, figured out how a backscatter x-ray works, made his own Aerogel, and played around with “bullet time” photography.

In this episode of Applied Science, Ben trains his o-scope on the CAN (Control Area Network) bus of a Tesla Model S to see what sorts of information he can glean from the data there. He shows you how to access the CAN bus connector, explains what some of…
