ECD SYSTEM


  1. OPERATION


    1. This system determines the deterioration of the engine oil and oil filter in accordance with the soot volume in the engine oil and oil filter. The ECM calculates the soot volume in the engine oil and oil filter in accordance with the engine speed, injection timing, injection volume and air-fuel ratio. The ECM converts the soot volume into pulse signals and transmits the signals to the meter ECU. The meter ECU counts the pulse signals as the soot volume, blinks the engine oil change reminder light when the cumulative value gets closer to a predetermined value, and illuminates the reminder light when the cumulative value reaches the predetermined value. Thus, this system informs the driver that the engine oil and the oil filter must be changed.

    2. In addition to controlling the illumination of the engine oil change reminder light by calculating the soot volume, the ECM blinks the reminder light when the vehicle travel distance reaches 25000 km, and illuminates it when the travel distance reaches 30000 km. Thus, this function enhances the reliability of the system.

      Tech Tips

      This system does not determine the deterioration of the engine oil based on the elapsed time. Even if the engine oil change reminder light does not illuminate, the engine oil and oil filter should be changed at 2-year intervals at the maximum.
