What does the acronym "MIL" stand for in automotive terminology?

The acronym "MIL" stands for Malfunction Indicator Lamp. This refers to the warning light on a vehicle's dashboard that alerts the driver to a problem with the engine or emissions control system. When the vehicle's onboard diagnostic system detects an issue that affects emissions or performance, the MIL illuminates, prompting the driver to investigate further.

The significance of the MIL is that it plays a crucial role in vehicle maintenance, as an illuminated lamp indicates that the vehicle may require servicing or diagnostic testing to identify the underlying issues. By understanding the function of the MAL, technicians and vehicle owners can take timely action to address potential problems before they lead to more serious issues or failures. This helps maintain the vehicle’s efficiency and compliance with environmental regulations.
