Malfunction Indicator Light
WARNING: This page is about a different car, the 2002 Mercury Villager. However, it is still accessible from the selected car via links, so may be relevant.
The Malfunction Indicator Light (MIL) will illuminate when ignition switch is turned to the ON position (bulb check), or when systems related to the EEC system malfunction during normal engine operation. For additional information, see SELF-DIAGNOSTICS - VILLAGER article.
