ACTIVE REAR WING SYSTEM


  1. FUNCTION OF MAIN COMPONENTS


    1. The main components of the active rear wing system have the following functions:

      Item Function
      Spoiler Control ECU Assembly Determines the active rear wing state based on information from the Hall IC integrated into the motor, and operates the motor in accordance with the vehicle speed and current driving mode to control the active rear wing.
      Active Rear Wing Assembly Active Rear Wing Ensures sufficient downforce while driving when raised.
      Rear Spoiler Motor

      • Raises or retracts the active rear wing.

      • A built-in Hall IC provides feedback on the rotation of the motor in the form of pulse signals to the spoiler control ECU assembly.
      Skid Control ECU Sends vehicle speed signals to the skid control ECU via CAN communication.
      Spoiler Control Switch Is used to raise or retract the active rear wing.
      Spoiler Control Switch Indicator Light Illuminates when the active rear wing is in a position other than the retracted position and goes off when it is in the retracted position.
      Combination Switch Assembly Drive Mode Select Sends the driving mode signal to the ECM.
      Luggage Compartment Door Lock Assembly Sends the luggage compartment door open/close signal to the main body ECU (multiplex network body ECU).
      Main Body ECU (Multiplex Network Body ECU) Sends the luggage compartment door open/close signal to the spoiler control ECU assembly.
      Combination Meter Assembly Multi-information Display

      • Disables or reenables the active rear wing system and sends the signal to the spoiler control ECU assembly.

      • Displays the raised/retracted state of the active rear wing.

  2. SYSTEM CONTROL

    Item Function
    Automatic Mode Control Automatically raises or retracts the active rear wing according to the driving mode when the vehicle speed reaches a specified speed.
    Manual Mode Control Raises or retracts the active rear wing when the spoiler control switch is operated by the user.
    Operation Cancelation Disables or reenables the active rear wing system via the multi-information display in the combination meter assembly.

    1. Automatic Mode Control

      Driving Mode Operation
      Except Eco Mode

      • Rises: vehicle speed exceeds approximately 80 km/h (50 mph)

      • Retracts: vehicle speed drops below approximately 40 km/h (25 mph)
      ECO Mode

      • Rises: vehicle speed exceeds approximately 130 km/h (81 mph)

      • Retracts: vehicle speed drops below approximately 40 km/h (25 mph)

      1. When the vehicle speed exceeds approximately 80 km/h (50 mph)*1or approximately 130 km/h (81 mph)*2, the spoiler control ECU assembly sends a signal to the rear spoiler motor to raise the active rear wing.

        Tech Tips

        *1: In other than ECO mode

        *2: In ECO mode

      2. The spoiler control ECU assembly counts pulse signals sent from the Hall IC in the motor and stops the motor when the active rear wing reaches the fully raised position.

      3. When the vehicle speed drops below approximately 40 km/h (25 mph) with the active rear wing raised, the spoiler control ECU assembly sends a signal to the rear spoiler motor to retract the active rear wing.

      4. The spoiler control ECU assembly counts pulse signals sent from the Hall IC in the motor and stops the motor when the active rear wing reaches the fully retracted position.

    2. Manual Mode Control

      Vehicle Speed Operation
      0 km/h (0 mph) (while stopped)

      • To raise: Press the spoiler control switch.

      • To retract: Press and hold the spoiler control switch for at least approximately 0.8 seconds to start the retraction operation and continue holding the switch until the retraction is complete.
      Between 0 km/h (0 mph) and 20 km/h (12 mph)

      • To raise: This operation is not available.

      • To retract: This operation is not available.
      20 km/h (12 mph) or more

      • To raise: Press the spoiler control switch.

      • To retract: Press the spoiler control switch.

      1. Raising Operation


        • When the spoiler control switch is operated with the power switch on (IG), the spoiler control ECU assembly sends a signal to the rear spoiler motor to raise the active rear wing.

        • The spoiler control ECU assembly counts pulse signals sent from the Hall IC in the motor and stops the motor when the active rear wing reaches the fully raised position.

      2. Retracting Operation


        • When the spoiler control switch is pressed and held with the power switch on (IG), after approximately 0.8 seconds, the spoiler control ECU assembly sends a signal to the rear spoiler motor to retract the active rear wing.

        • When the vehicle speed is 20 km/h (12 mph) or more and the spoiler control switch is pressed, the spoiler control ECU assembly sends a signal to the rear spoiler motor to retract the active rear wing.

        • The spoiler control ECU assembly counts pulse signals sent from the Hall IC in the motor and stops the motor when the active rear wing reaches the fully retracted position.

    3. Initialization


      1. The ECU built into the rear spoiler motor stores the initial position of the active rear wing. The initial position is not cleared even if the cable is disconnected from the negative (-) battery terminal, or if fuses or rear spoiler motor connectors are disconnected. However, after removing or reinstalling active rear wing components, or replacing the rear spoiler motor, the stored initial position data must be cleared and/or initialization must be performed. For details, refer to the Repair Manual.
