DESCRIPTION
The MIL (Malfunction Indicator Lamp) is used to indicate vehicle malfunction detections by the ECM.
By turning the ignition switch ON, 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 ON, the MIL should be
illuminated and should then turn OFF. If the MIL remains illuminated or is not illuminated, conduct the
following troubleshooting procedure using an intelligent tester.
