What is an OBD2 Scanner and Why Do You Need One? (obd2 сканер как пользоваться)
An OBD2 scanner, also known as an OBD2 reader or diagnostic tool, is an electronic device that connects to your car’s onboard diagnostic system (OBD) port. This port, usually located under the dashboard on the driver’s side, provides access to a wealth of information about your vehicle’s performance, emissions, and potential problems. Using an OBD2 scanner lets you read and interpret diagnostic trouble codes (DTCs), which are essentially error messages generated by your car’s computer. These codes pinpoint specific issues, saving you time and money on unnecessary repairs. Moreover, many modern OBD2 scanners offer advanced features like live data streaming, freeze frame data, and emissions readiness checks.
