Malfunction indicator lamp (with European OBD) (Mitsubishi Matrix)

The malfunction indicator lamp lights up to warn the driver that there is a malfunction in the vehicle. However, if the detected malfunction does not occur after 3 consecutive driving cycles, the lamp goes out. The lamp lights up immediately after the ignition is turned on (without starting the engine), which indicates that it is in good condition.
