Engine scans are standard automotive diagnostic practice in both the USA and Brazil. In Brazil, while 'leitura do motor' is the technical translation, many mechanics use the English term 'scan' directly. This procedure became increasingly common after OBD-II systems became mandatory in vehicles. In automotive shops across both countries, discussing engine scans is routine when troubleshooting vehicle problems.
