What is the purpose of a scan tool?

Explanation:
A scan tool serves as the link to the vehicle’s computer. It plugs into the OBD-II port and talks to the engine control unit and other modules, pulling diagnostic trouble codes that explain why the check engine light or other warning indicators came on. Beyond just codes, it can show real-time sensor data, monitor system readiness, and help you verify that a repaired fault is actually cleared and behaving properly. While some advanced tools can update software or clear codes, those are secondary functions. The essential purpose is to communicate with the vehicle’s computer and read codes to guide diagnosis and repair.
