What does an automotive mechanic do?

An automotive mechanic investigates vehicle problems, performs maintenance and repairs, and checks that completed work addresses the original concern. The job involves more than replacing worn parts: a technician must connect symptoms with possible causes and decide what to inspect or test next. Work can involve mechanical components, electrical circuits and electronic controls. Documenting findings and explaining recommended repairs also belong to the role. The central responsibility is to make a sound diagnosis rather than assume that a fault code identifies the part that needs replacing.
