Malfunction Indicator Lamp: Description and Operation
When the ignition switch is turned ON, ECM causes the main relay to turn ON (close the contact point). Then, ECM being supplied with the main
power, turns ON the malfunction indicator lamp (MIL). When the engine starts to run and no malfunction is detected in the system, MIL goes OFF
but if a malfunction was or is detected, MIL remains ON even when the engine is running.
