Delphi-Common Rail System – MIL (Malfunction Indicator Lamp)

The MIL is located in the instrument cluster and shows an engine icon (international standard).

The MIL warns the driver that the EOBD system has detected an emissions-related fault in a component or system.

If an emissions-related fault is detected and if this fault is confirmed during the third driving cycle, the MIL is switched on.

After the MIL has been switched on, a fault log is created in the PCM. The fault logs contain information regarding the type of fault and the time since the MIL was activated.

The MIL ensures that a fault is recognized in time. The defect can be repaired in good time and the emission of exhaust gas with high levels of pollutants is avoided.
