Question

Quizplus · Accepted Answer

A scan tool is primarily used for reading diagnostic trouble codes, monitoring real-time data from various sensors and systems, and in some cases, programming vehicle systems. It is not typically used to directly test the physical or electrical properties of a circuit, which is more the domain of tools like multimeters or oscilloscopes.
