A car computer scanner (also known as an OBD-II scanner or diagnostic tool) connects to a vehicle’s onboard diagnostics system to identify issues with its emissions, engine, transmission, or other functions. It can also reset a check engine light and read pending codes.
Whether you’re an auto hobbyist or a professional mechanic, the right scan tool can help you fix cars faster and more accurately. Look for features that align with your needs, like a clear display and easy-to-use interface. More-advanced models offer advanced diagnostic functions such as freeze frame data, I/M readiness tests, and component testing. Some even have a database of manufacturer-specific troubleshooting procedures and repair information.
Connecting with Your Car: The Power of a Car Computer Scanner in Maintenance
You’ll want to find a model that works with the make and year of your vehicle, and it should be compatible with the engine type. Most scan tools require you to enter the vehicle identification number, or VIN, which you can find on a sticker normally located in the lower corner of the windshield, on the driver’s side. The VIN is also often printed on the vehicle’s warranty card.
