Understanding OBD2 and Diagnostic Trouble Codes

OBD2, or On-Board Diagnostics II, is a standardized system that allows external electronics to interface with a vehicle’s computer and retrieve diagnostic information.

Factors to consider include compatibility with your vehicle’s make and model, operating system compatibility (Windows, Mac, etc.), and the specific functions offered by the software. Some software focuses solely on clearing codes, while others offer advanced features like live data streaming, graphing, and logging.

Free vs. Paid USB OBD2 Software
