A Class 2 scan tool is a diagnostic device used primarily in automotive applications to communicate with a vehicle's onboard computer systems via the Class 2 data bus protocol. This protocol is commonly found in General Motors vehicles and allows the scan tool to retrieve diagnostic trouble codes (DTCs), monitor vehicle parameters, and perform system tests. Class 2 scan tools are essential for troubleshooting and diagnosing issues within the vehicle's electronic systems, including the engine, transmission, and various modules.
