With advancements in technology, came the improvements of OBD systems, and the latest ones use a standardized digital communications port that provides real-time data.

With OBD1, the goal was to develop a diagnostics system which focuses on the emission control systems of a vehicle. OBD2 has better signalling protocols and messaging formats. The OBD2 is a better system, in the sense that it provides standardized trouble codes for car owners who experience engine problems. Finally, OBD1 is typically connected to the console, so that the port can be diagnosed and data can be read. OBD2 is remotely used to diagnose ports, and reads data through a Bluetooth connection.

As such, it is easier to diagnose a problem remotely if you have a car made with an OBD2 system. OBD1 has good diagnostic capabilities, while OBD2 has better signalling protocols and messaging formats. Cite APA 7 ,.
