LUGGAGE COMPARTMENT DOOR OPENER SYSTEM SYSTEM DESCRIPTION


  1. LUGGAGE COMPARTMENT DOOR OPENER SYSTEM DESCRIPTION


    1. w/ Power Trunk Lid System


      1. If the luggage door opening switch assembly is pressed when the main body ECU (multiplex network body ECU) is not receiving a luggage door opening cancel switch assembly ON signal, and the luggage compartment door is closed, a luggage door closer assembly open operation signal is sent to the luggage closer motor assembly via CAN communication. When the luggage closer motor assembly receives that signal, it activates the luggage compartment door closer, and unlatches the luggage compartment door.

    2. w/o Power Trunk Lid System


      1. If the luggage door opening switch assembly is pressed when the main body ECU (multiplex network body ECU) is not receiving a luggage door opening cancel switch assembly ON signal, and the luggage compartment door is closed, a luggage compartment door lock assembly open operation signal is sent to the main body ECU (multiplex network body ECU). Then the main body ECU (multiplex network body ECU) unlatches the luggage compartment door.

  3. CONSTRUCTION AND OPERATION (w/ Power Trunk Lid System)


    1. Luggage Door Closer Assembly:


      • The luggage door closer assembly is mounted on the luggage compartment door and consists mainly of a link mechanism and a closer motor. It provides two functions: the closer function to automatically close the luggage compartment door, and the opener function to disengage the striker from the luggage door closer assembly latch.

      • The luggage door closer assembly contains 1 courtesy light switch and position detection switch in the closer motor.

    2. Luggage Closer Motor Assembly:


      1. General


        • In closer mode, this system operates as follows: when the state of the luggage compartment door changes from open to ajar, the signal from the courtesy light switch changes from on to off. Upon receiving this signal, the ECU actuates the motor in order to push and turn the latch via the link mechanism. As a result, the latch engages with the striker in order to fully close the luggage compartment door.

      3. Fail-safe


        • If a system malfunction is detected by the luggage closer motor assembly, the luggage closer motor assembly deactivates the system. However, even if the system is deactivated, the luggage compartment door can be opened and closed manually.
