A launch scan tool, also known as a scan tool or code reader, is a diagnostic tool used to retrieve and interpret diagnostic trouble codes (DTCs) from a vehicle’s electronic control unit (ECU). These codes provide valuable information about potential issues with the vehicle’s systems, such as the engine, transmission, or brakes. Launch scan tools vary in their capabilities, with some offering basic code reading and clearing functions, while others provide more advanced features such as live data streaming, actuator testing, and ECU programming.
Launch scan tools have become increasingly important as vehicles have become more reliant on electronic systems. By providing quick and easy access to diagnostic information, they empower mechanics and vehicle owners to identify and resolve issues more efficiently, reducing downtime and repair costs.
The development of launch scan tools has paralleled the advancements in automotive technology. Early scan tools were simple devices that could only read and clear codes, but modern tools offer a wide range of capabilities that allow technicians to perform in-depth diagnostics and repairs.
