SLIDING ROOF SYSTEM DETAILS


  1. SYSTEM CONTROL


    1. The sliding roof system has the following functions:

      Function Outline
      Manual Open-and-close This function causes the sliding roof to open (or close) while the slide open switch (or slide close switch) is pressed for less than 0.3 seconds. The sliding roof stops as soon as the switch is released.
      One-touch Auto Open-and-close This function causes the sliding roof to open (or close) while the slide open switch (or slide close switch) is pressed for 0.3 seconds or more. The sliding roof stops as soon as the switch is released.
      Manual Tilt Up-and-down This function causes the sliding roof to tilt up (or tilt down) while the tilt up switch (or tilt down switch) is pressed for less than 0.3 seconds. The sliding roof stops as soon as the switch is released.
      One-touch Auto Tilt Up-and-down This function enables the sliding roof to be fully tilted up (or down) by the tilt up switch (or tilt down switch) for 0.3 seconds or more.
      Jam Protection The jam protection function automatically stops the sliding roof and moves it open halfway (or fully tilts up) if a foreign object gets jammed in the sliding roof during close or tilt down operation.
      Key Off Operation The key off operation function makes it possible to operate the sliding roof for approximately 43 seconds after the engine switch is turned on (ACC) or off, if the front doors are not opened. While the sliding roof is operating in auto mode, the operation stops immediately after 43 seconds have elapsed.
      Mechanical Key-linked Open-and-close* When the electrical key transmitter sub-assembly is not in the detection area, the driver door is locked, and the mechanical key in the driver door is turned and maintained in the lock direction for 1.5 seconds or more, the sliding roof control ECU activates the sliding roof motor to close the sliding roof while the mechanical key is turned. Similarly, when the driver door is unlocked, turning and maintaining the driver door mechanical key in the unlock direction for 1.5 seconds or more causes the sliding roof to be opened.
      Electrical Key Transmitter Subassembly- linked Open-and-close* When the main body ECU receives an unlock/lock signal from the electrical key transmitter subassembly continuously for longer than 2.4 seconds, the sliding roof control ECU controls the sliding roof motor in accordance with the signal to open/close the sliding roof.
      Lock Switch-linked Close When the lock switch on the outside door handle is pressed for 3 seconds or more with the electrical key transmitter sub-assembly in the detection area and all the doors locked, the sliding roof control ECU activates the sliding roof motor to close the sliding roof while the lock switch is pressed.
      Sliding Roof Open Warning When the engine switch is turned from on (IG) to off and the driver door is opened with the sliding roof open, the multi buzzer in the combination meter assembly sounds once. Then, a warning message appears on the multi-information display.

      Tech Tips

      *: Customizable parameters can be configured by means of the customized body electronics system. For details, refer to the Repair Manual.

      The sliding roof control ECU memorizes the initial position of the sliding roof. This memory is not cleared if the battery terminals are disconnected. However, initialization is necessary after the sliding roof drive gear sub-assembly is replaced. For details, refer to the Repair Manual.

    2. Jam Protection Function


      1. To control the jam protection function, the ECU monitors the amount of movement and judges jamming of the sliding roof based on the pulse signals from the Hall IC1, and the moving direction of the sliding roof from the phase difference between the pulses from the Hall IC1 and Hall IC2.
