СИСТЕМА ECD - Цепь контрольной лампы неисправности MIL


DESCRIPTION

The MIL (Malfunction Indicator Lamp) is used to indicate vehicle malfunctions detected by the ECM. When the ignition switch is turned on (IG), 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 (IG), 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 the intelligent tester.

2.CHECK WHETHER MIL TURNS OFF

  1. Connect the intelligent tester to the DLC3.

  1. Turn the ignition switch on (IG) and turn the tester on.

  1. Select the following menu items: Powertrain / Engine and ECT / DTC.

  1. Check if any DTCs have been stored. Note down any DTCs.

  1. Clear the DTCs (See page Нажмите здесь).

  1. Check if the MIL goes off.

    Standard:
    The MIL goes off.
