ECD SYSTEM


  1. FUNCTION


    1. The ECM controls the length of time for which the current is applied to the glow plug relay assembly when the engine starts in accordance with engine coolant temperature to control the length of time for which the current is applied to the glow plug assemblies.

    2. When the ignition switch is turned from off to ON*1 or the engine switch is turned on (START)*2, the ECM operates the glow plug relay assembly to heat the glow plug assemblies rapidly. At that moment, the glow indicator light in the combination meter assembly is illuminated to inform the driver that the glow plug assemblies are being heated.


      • *1: Models without smart entry and start system.

      • *2: Models with smart entry and start system.

    3. When the engine starts and the starter signal is off, after-glow control is conducted. When the temperature of the glow plug assembly reaches a predetermined level during after-glow control, it is maintained at a nearly constant level using the self-temperature-controlling function of the glow plug assembly.
