A Diagnostic Scan Tool Fault Code Reader, often shortened to OBD2 scanner, is an essential tool for any car owner or mechanic. These handy devices plug into your car’s onboard computer system (the OBD2 port) and read the error codes stored when something isn’t right. This gives you valuable insight into what’s going on under the hood, often before a problem even becomes noticeable.
