ECD SYSTEM


  1. OPERATION


    1. In the oil maintenance management system, the oil change reminder indicator light*1 in the combination meter blinks or turns on, or a message is displayed on the multi-information display*2 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 that 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 light 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 blinks the indicator in the combination meter 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 turns on the indicator*1.

    3. 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*2.

      Multi-information Display*2 OIL MAINTENANCE REQUIRED SOON appears for approximately 15 seconds
      When the running distance exceeds a predetermined distance since the switch was turned on Oil Change Reminder Indicator Light*1 Turns on
      Multi-information Display*2 OIL MAINTENANCE REQUIRED warning remains on

    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 oil change reminder indicator light or the oil level warning light turns on or blinks, the ECM memory must be reset. For details, refer to the Repair Manual. (Models with segment LCD type multi-information display)

      • 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)
