СИСТЕМА ECD - Цепь контрольной лампы неисправности MIL


DESCRIPTION

The MIL (Malfunction Indicator Lamp) is used to indicate vehicle malfunction detections by the ECM. By turning the ignition switch to the ON position, power is supplied to the MIL circuit, and the ECM provides the circuit ground which illuminates the MIL.
The MIL operation can be checked visually: When the ignition switch is first turned to the ON position, the MIL illuminates and then goes off. If the MIL remains illuminated or is not illuminated, conduct the following troubleshooting procedure using an intelligent tester.
