What is an OBD2 Scanner?
An OBD2 scanner is a device that is used to diagnose and fix car issues. It plugs into the diagnostic port on your vehicle, and it uses scanners to read codes from various systems in your car. This can include emissions, engine performance, cruise control, airbags, and more.
Once you've installed the correct scan tool for your make and model of vehicle, you can run diagnostics by pressing a button or using an app on your phone. This will show you the results of any problems that were detected as well as how much Repair Time Remaining (RTR) exists before they need to be fixed. If there are any issues that require immediate attention or replacement parts have been ordered but not yet shipped to the dealership, then this will also be indicated on the display screen.
OBD2 scanners are versatile tools that can help keep your vehicles running smoothly and efficiently – perfect for those who love driving their cars responsibly.
