STOP AND START SYSTEM


  1. OUTLINE


    1. To achieve low emissions and enhanced fuel economy, the stop and start system has been developed.

    2. The stop and start system automatically stops the engine when the vehicle comes to a stop, such as when the vehicle stops at a red traffic light. When starting off, the engine is automatically restarted by simply depressing the clutch pedal, without requiring extra activity from the driver.

    3. The stop and start system consists of an engine stop and start ECU with a built-in backup boost converter and a permanently engaged starter assembly.

    4. Based on signals from various sensors, switch, and the ECM, the engine stop and start ECU controls the stopping and starting of the engine.

    5. To allow management of the life span of the starter assembly, the engine stop and start ECU counts the number of times the starter operates. If the number exceeds a threshold, the ECU blinks the stop and start cancel indicator light to inform the driver of recommended replacement timing.

      Tech Tips

      After the starter assembly has been replaced, it is necessary to clear the record of the number of times that the starter assembly has been operated. For details, refer to the Repair Manual.
