Federal regulations require OBD systems to flag any fault that could push tailpipe emissions above 150% of the certified limit. In the United States, on-board diagnostics (OBD) is mandatory for emissions compliance, and today’s fleets are turning that requirement into a competitive advantage. By leveraging real-time fault-code data, operators
