OBD-II Drive Cycle General Description
OBD-II DRIVE CYCLEA diagnostic trouble code can be monitored by carrying out a short drive in accordance with the OBD-II drive cycle patterns. In other words, doing such a drive allows to regenerate any kind of trouble which involves illuminating the check engine/malfunction indicator lamp and to check if the repair procedure has eliminated the trouble (the check engine/malfunction indicator lamp is no more illuminated).
NOTE: Some drive cycle monitors refer to a system or a group of components rather than a specific component.
