СИСТЕМА ECD


  1. OPERATION


    1. In the oil maintenance management system, turns on, a message is displayed on the multi-information display to inform the driver that it is necessary to change the engine oil, when one of the following conditions is met: when the running distance exceeds a predetermined distance since the initial oil change or the last oil change, when the soot volume in the engine oil is calculated based on the engine operating conditions exceeds a predetermined volume, or when the oil level exceeds the level predetermined by the catalyst support control.

    2. When controlling the oil change reminder indicator based on the running distance, if the ECM detects that the running distance since the initial or last oil change is approximately 14500 km (9000 miles), the ECM displays "OIL MAINTENANCE REQUIRED" on the multi-information display for 15 seconds after the ignition switch is turned to ON, and then after another approximately 500 km (310 miles) of running distance without any oil change, the ECM constantly displays the message.

    3. When controlling of the oil change reminder indicator based on the oil level sensor, when the sensor detects that the engine oil level exceeds a predetermined level, the ECM displays a message on the multi-information display.

      Oil Upper Level Switch
      When the switch turns on Multi-information Display OIL MAINTENANCE REQUIRED SOON appears for approximately 15 seconds
      When the running distance exceeds a predetermined distance since the switch was turned on Multi-information Display OIL MAINTENANCE REQUIRED warning remains on
      Oil Lower Level Switch
      When the switch turns on Multi-information Display ENGINE OIL LOW appears

    4. The ECM calculates soot volume from the injection volume, injection timing and intake air volume in order to operate this system.

    5. The soot volume largely depends on injection ending timing and air-fuel ratio. The ECM calculates soot volume from this information as shown in the graphs below.

      Tech Tips

      When the engine oil is changed after the message is displayed on the multi-information display, the ECM memory must be reset. For details, refer to the Repair Manual. (Models with dot LCD type multi-information display)
