Malfunction Indicator Light: Notes

All models are equipped with a Malfunction Indicator Light (MIL), located at instrument cluster. See Figure. As a bulb check, MIL illuminates for about 2 seconds when ignition switch is turned to ON position and engine is not running. MIL also illuminates when a system failure has been detected and a corresponding DTC has been set in ECM memory. MIL may also flash if ECM detects an engine misfire severe enough to cause catalytic converter failure. Not all DTCs will activate MIL. If MIL is ON and no DTCs are in memory, problem may be intermittent. See INTERMITTENTS in TROUBLE SHOOTING - NO-CODES article.
