Engine diagnostics have become standard practice in both Brazilian and American automotive repair shops since the 1990s with the advent of on-board diagnostic (OBD) systems. In Brazil, many independent mechanics now have diagnostic scanners available, and customers often request 'diagnóstico do motor' as a first step when experiencing vehicle problems. This reflects the shift toward computerized automotive maintenance in Latin America.
