Malfunction Indicator Lamp Function

Drive cycles and trips are used by OBD-II software strategy to control Malfunction Indicator Lamp (MIL) off function. MIL is illuminated whenever a DTC is stored in memory. MIL is turned off after 3 consecutive drive cycles or trips are completed, without identical fault being present. Number of drive cycles or trips, varies with each system monitor. See appropriate test in this section.
