On-Board Diagnostics (OBD) Program Overview
emissions exceed threshold levels (e.g., 1.5 x standards) • Actual in-use vehicle testing by engineers with implanted faults, dyno and on-road driving, data logging. o Do the monitors run when they are supposed to? o Do they detect malfunctions that are implanted? o Is the right data stored when a malfunction is detected? o .. And so on.
