2.7 DTCs and MIL Status
When the vehicle’s on-board computer detects a failure in an emissions-related
component or system, the computer’s internal diagnostic program assigns a
diagnostic trouble code (DTC) that points to the system (and subsystem) where
the fault was found. The diagnostic program saves the code in the computer’s
memory. It records a “Freeze Frame” of conditions present when the fault was
found, and lights the Malfunction Indicator Lamp (MIL). Some faults require
detection for two trips in a row before the MIL is turned on.
