SLIDING ROOF SYSTEM INITIALIZATION


  1. INITIALIZE SLIDING ROOF SYSTEM

    Note


    • Before starting this operation, make sure that the guide rails are not deformed and there is no foreign matter on the guide rails.

    • When the sliding roof glass sub-assembly or sliding roof drive cable sub-assembly is adjusted or removed/installed, or the sliding roof drive gear sub-assembly is replaced, the sliding roof ECU (sliding roof drive gear sub-assembly) must be initialized. If initialization is not performed, the auto operation function, jam protection function, key-off operation function, key-linked function, wireless transmitter-linked function and sliding roof open warning function may not operate, or the sliding roof may move in reverse or become misaligned.

    • During initialization, do not apply a physical shock, such as opening/closing a door or driving the vehicle at 5 km/h (3 mph) or more, to the vehicle and do not perform any electrical operations.

    • Make sure not to turn the power switch on (IG) or off during initialization.

    • When a sliding roof ECU (sliding roof drive gear sub-assembly) is replaced, DTC B2343 is stored. Clear the DTC after initialization.

    Tech Tips


    • The sliding roof switch is installed in the map light assembly.

    • If the auxiliary battery has been replaced, it is not necessary to initialize the sliding roof ECU (sliding roof drive gear sub-assembly).


    1. Perform initialization according to the table below.

      Condition of Sliding Roof Proceed to
      Auto slide open and close/tilt up and down functions do not operate. Procedure A
      Automatically moves, but the sliding roof glass does not stop at the correct position (misalignment occurs), or the sliding roof glass moves in the reverse direction during tilt down operation. Procedure B
      Automatically moves, but the sliding roof glass moves in the reverse direction during slide close operation. Procedure C

      1. Procedure A


        1. Turn the power switch on (IG).

        2. Fully close the sliding roof glass and release the sliding roof switch (map light assembly).*1

        3. Press and hold the CLOSE or UP switch.

          Note

          Press and hold the CLOSE or UP switch until *2 is completed. If the switch is released before *2 is completed, repeat the operation from *1.

        4. The sliding roof glass performs the following operations: tilt up → 1 second pause → tilt down → slide open → slide closed.

        5. After the roof glass stops in the fully closed position, release the switch.*2

          Tech Tips

          The initialization process ends when this operation completes.

        6. Make sure that the sliding roof auto function operates normally.

      2. Procedure B


        1. Turn the power switch on (IG).

        2. Press the UP switch to move the sliding roof glass to the fully tilted up position and then release the UP switch.

          Tech Tips


          • If the sliding roof glass cannot be fully tilted up due to misalignment of the roof glass, press and hold the CLOSE switch until the sliding roof glass stops closing, and then press and hold the UP switch until the sliding roof glass stops tilting up.

          • If the sliding roof glass moves in the reverse direction while it is being closed, repeatedly tap the CLOSE switch at short intervals to fully close the sliding roof glass. When the sliding roof glass is fully closed, press the UP switch to move the sliding roof glass into the fully tilted up position.

        3. Press and hold the UP switch again until the sliding roof glass completes the following operations: pause for approximately 10 seconds or more → tilt inching motion → 1 second pause → tilt down → slide open → slide closed.*1

          Note


          • Press and hold the UP switch until *2 is completed.

          • While performing *1, if the UP switch is released before "pause for approximately 10 seconds or more" completes, start this step over.

          • While performing *1, if the UP switch is released after "pause for approximately 10 seconds or more" completes, but above movements complete, perform procedure A to initialize the position of the sliding roof glass.

        4. After the roof glass stops in the fully closed position, release the switch.*2

          Tech Tips

          The initialization process ends when this operation completes.

        5. Make sure that the sliding roof auto function operates normally.

      3. Procedure C


        1. Turn the power switch on (IG).

        2. Press and hold the CLOSE switch until the sliding roof glass completes the following operations: slide closed → move in the reverse direction → pause for approximately 10 seconds or more → slide closed → tilt up → 1 second pause → tilts down → slide open → slide closed.*1

          Note


          • Press and hold the CLOSE switch until *2 is completed.

          • While performing *1, if the CLOSE switch is released before "pause for approximately 10 seconds or more" completes, start this step over.

          • While performing *1, if the CLOSE switch is released after "pause for approximately 10 seconds or more" completes, but before the above movements complete, perform procedure A to initialize the position of the sliding roof glass.

        3. After the roof glass stops in the fully closed position, release the switch.*2

          Tech Tips

          The initialization process ends when this operation completes.

        4. Make sure that the sliding roof auto function operates normally.
