Because they follow a specific set of standards, OBD2 scan tools are easy to use. They fit the same connector, which is present in all vehicles, as defined by SAE standard J1962. Often these connections are located under the dashboard near the driver’s seat, depending on the vehicle’s make.

Professional-level scan tools have much greater capabilities and require some training. Diagnostic technicians can do much more, such as perform specific bi-direction tests on running vehicles or connect to OEM-specific devices and controls to get feedback that won’t normally generate error codes.

Types of OBD2 scanners

Code Readers

These are cheaper, simpler devices that are plugged into a vehicle solely for reading and clearing error codes. They don’t provide any additional information, and may not reflect a wider set of codes in use by various manufacturers. An OBD2 scanner meant for GM vehicles, for instance, will read only the basic codes saved to memory and additional codes for GM cars and trucks only. Additional information is usually provided online or via a reference pamphlet that lists the available codes with brief explanations for each one.

Scan Tools

Scan tools are more sophisticated and are available in several levels of complexity, from compact consumer versions to powerful diagnostic computers in use by commercial auto shops.
Professional or more advanced versions will include options like review of both live and recorded data, options for manufacturer-specific codes, customizable menus, parameters, tests, and code reads, and extensive technical information on troubleshooting each code. Basically, every vehicle sensor that transmits signals to the onboard computer produces codes that can be read with an OBD2 scanner.
They can also read “soft” codes, or codes that have been detected but not yet logged. Many scanners, for instance, must detect a code on three successive vehicle starts before it’s included in the diagnostics, in order to allow for anomalies like false emissions readings or random computer errors.
