MIL Does Not Come ON with Ignition Switch ON and Engine Stop (but Engine Can Be Started)S7RS0B1104011
Wiring Diagram
Circuit Description
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, transmits indication ON si gnal of MIL to combination meter in order to turn MIL
ON. And then, combination meter turns MIL ON. When the engine starts to run and no malfunction is detected in the
system, ECM transmits MIL indication OFF signal to combination meter in order to turn MIL OFF. And then,
combination meter turns MIL OFF, but if a malfunction was or is detected, MIL remains ON even when the engine is
running.
