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.
