Malfunction Indicator Lamp: Description and Operation

MALFUNCTION INDICATOR LAMP (MIL)


Malfunction Indicator Lamp (MIL):






The malfunction indicator lamp (MIL) informs the driver that the PCM has detected an OBD emission-related component or system fault. When this occurs on a California calibrated engine, an OBD DTC will be set. On a federal calibrated engine and transmission, certain faults will also illuminate the MIL.
- On all vehicles, the MIL is located in the instrument cluster.
- The indicator is illuminated by a PCM message sent through the standard corporate protocol (SCP) communications network to the instrument cluster.
- An engine or transmission with federal calibration operating in the failure mode effects management (FMEM) will cause the MIL to be Illuminated.
- To turn off the MIL after a repair, a clear DTCs command from the scan tool must be sent to the PCM.
- For any MIL concern, go to Symptom Charts. Symptom Charts
