KINETIC DYNAMIC SUSPENSION SYSTEM


  1. FUNCTION OF MAIN COMPONENTS

    Component Function
    Front and Rear Stabilizer Bars Restrain roll to ensure driving stability.
    Front and Rear Stabilizer Control Cylinders Absorb the impact from the road surface to ensure ride comfort.
    Stabilizer Control with Accumulator Housing Assembly Accumulator Pressure Sensor Detects the hydraulic pressure and transmits its signal to the stabilizer controlECU.
    Stabilizer Control Solenoid Valve Opens and closes the piping between each stabilizer control cylinder chamber and the accumulator.
    Accumulator Absorbs the pressure from the front stabilizer with tube cylinder assembly and rear stabilizer control cylinder.
    Combination Meter Assembly KDSS Indicator Light Illuminates to inform the driver when the stabilizer control ECU has detected a malfunction in the KDSS.
    Steering Angle Sensor Detects the steering direction and the angle of the steering wheel.
    Yaw Rate Sensor Assembly

    • Detects the vehicle's yaw rate.

    • Detects the vehicle's longitudinal and lateral acceleration and deceleration.
    Stabilizer Control ECU Switches the stabilizer control valve based on the signals from the sensors and ECUs.
    Skid Control ECU Sends the vehicle speed signal to the stabilizer control ECU.

  2. SYSTEM CONTROL


    1. In accordance with the vehicle speed signal and the signals received from the steering angle sensor and yaw rate sensor assembly, the stabilizer control ECU controls the 2 stabilizer control solenoid valves in order to switch the hydraulic circuit in the system.

    2. The 2 stabilizer control solenoid valves are controlled with the same timing and in the same direction.

    3. While driving at a low speed, the stabilizer control solenoid valve is off and the oil passage between the chamber and accumulator is open.

      *3 Front Suspension

  3. FAIL-SAFE


    1. If a malfunction occurs in any of the sensors or actuators, the stabilizer control ECU prohibits the system control.

  4. DIAGNOSIS


    1. If the stabilizer control ECU detects a malfunction in the KDSS, it illuminates the KDSS indicator light in the combination meter assembly to alert the driver of the malfunction.

    2. The stabilizer control ECU will also store a Diagnostic Trouble Code (DTC). The DTC can be accessed through the use of an intelligent tester II. For details, refer to the Repair Manual.
