Malfunction Indicator Lamp (MIL) (Check Engine Soon - NAS)

The MIL operation is controlled by the ECM and the instrument pack software. The lamp illuminates in an amber color at all times with the ignition in position II and the engine not running. When the engine is started, the MIL is extinguished, providing that no OBD related faults are active. If the MIL remains illuminated or illuminates when driving, a fault is present and must be investigated as soon as possible.
