What is an OBD2 Scanner?

An OBD2 scanner is a basic diagnostic tool designed to read and clear diagnostic trouble codes (DTCs) from a vehicle’s onboard computer. These codes are generated when the vehicle’s sensors detect a problem within a system. OBD2 scanners are primarily used to identify the source of a “check engine” light. They are typically more affordable and user-friendly, making them suitable for DIY car enthusiasts and everyday drivers.

What is an Automotive Scan Tool?

An automotive scan tool is a more advanced diagnostic device that offers a wider range of functionalities beyond reading and clearing DTCs. These tools can access various vehicle systems, including the engine, transmission, ABS, airbags, and more. They can provide live data streams, perform bi-directional controls (activating components like fuel injectors or solenoids), and even program certain modules. Automotive scan tools are typically used by professional mechanics and technicians for in-depth diagnostics and repairs.
