OBD2 Scanners & Scan Tools

Vehicle Diagnostic Code Readers & Scan Tools

An OBD2 scanner allows you to check your vehicle’s diagnostic system like the pros do. OBD means “Online Board Diagnostic System”

Since the 1980’s standardized Onboard Diagnostic systems (first OBD-I and currently OBD-II) have been mandated for virtually all cars and light trucks manufactured for the US market, and have provided automotive technicians, and increasingly DIYers with insight into the increasingly complex inner workings of modern passenger vehicles. Traditionally professional grade diagnostic results required large and/or expensive scanning tools to translate diagnostic trouble codes (DTCs) and other data generated by the internal computer networks of your vehicle when the check engine/malfunction indicator light (MIL) on the dashboard lights up. Now there is a much better way by using the OBD2 scanners and scan tools featured here.

You’ll find a variety of brands and styles of OBD2 scanners here in a variety of price ranges. To learn more about each scanning tool, simply click on any of the photos on this page. Some of these are really quite inexpensive, and highly rated by consumers, and everyone with a vehicle should have one on hand!

It’s never been easier to check the diagnostic systems of your vehicles. If you get one of these scanners like the auto repair shops have, it saves you money, and allows you to know what is wrong with your vehicle, so you can begin repairs.

Keep in mind that OBD2 scanners work on vehicles 1996 and newer, and OBD1 are for models 1981-1995.

These also make great gifts for home mechanics, new drivers, and even professional auto mechanics!
