Will OBD3 Make Your Car Spy on You?

OBD 2, which stands for the second iteration of On Board Diagnostics, standardized the plug and codes that the first OBD systems used, so that one scan tool connector would attach to any make/model, and the codes would all have the same number, description, and meaning. It was a super helpful change for DIY users, because one scan tool would be able to scan any of their cars made after 1996, no mater who made the car!

OBD 3, however, is the theoretical next step, and given all the interconnected wireless devices we have gotten used to and have become okay with spying on us, it’s an interesting topic to speculate on…
