Secondly, what is a CAN bus system? From Wikipedia, the free encyclopedia. A Controller Area Network (CAN bus) is a robust vehicle bus standard designed to allow microcontrollers and devices to communicate with each others' applications without a host computer.

One may also ask, what is the difference between OBD and obd2?

Main Differences of OBD and OBD2 OBD is connected to the console of a vehicle, while OBD is remotely connected. OBD was used in the early years of the vehicle manufacturing industry. OBD offers decent diagnostic capabilities, while OBD2 features better-messaging formats and signaling protocols.
