Malfunction Indicator Lamp: Description and Operation

A malfunction indicator lamp illuminates to notify the driver that there is a problem with the vehicle. However, the MIL will go off automatically after 3 subsequent sequential driving cycles without the same malfunction. Immediately after the ignition switch is turn on (ON position - do not start), the MIL will illuminate continuously to indicate that the MIL operates normally.
