Question

Quizplus · Accepted Answer

Technician B is correct because modern vehicles, especially those equipped with systems like SBEC IIIA, typically require a scan tool to read diagnostic trouble codes (DTCs). Cycling the ignition switch to flash codes on the MIL is an older method not commonly used with advanced vehicle electronics.
