SLIDING ROOF SYSTEM INITIALIZATION


  1. INITIALIZE SLIDING ROOF ECU (SLIDING ROOF DRIVE GEAR SUB-ASSEMBLY)

    Note


    • When the sliding roof glass, sliding roof ECU (sliding roof drive gear sub-assembly) or sliding roof housing is replaced or removed and installed, the sliding roof drive gear requires initialization (pulse sensor initial position setting), as the glass position cannot be determined. If initialization is not performed, the auto slide open and close / tilt up and down 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 the following electrical operations:


      1. Cranking the engine

      2. Turning the power switch from on (IG) to off

      3. Operating the power window switches

      4. Operating the window defogger switch

      5. Operating the blower switch

      6. Locking/Unlocking a door

      7. Operating the headlight dimmer switch

      8. Operating the power seat switch

    Tech Tips

    When the cable of the negative (-) auxiliary battery terminal or the drive gear connector is disconnected and reconnected, sliding roof drive gear (pulse sensor initial position setting) initialization is not necessary.


    1. Perform initialization according to the table below.

      Condition of Sliding Roof Proceed to
      Auto slide open and close / tilt up and down function does not operate Procedure A
      Sliding roof moves in reverse direction during tilt down operation Procedure B
      Sliding roof moves in reverse direction during slide close operation Procedure C

      Tech Tips

      Before performing initialization, make sure that there is no foreign matter on the guide rails and the guide rails are not deformed.


      1. Procedure A


        1. Turn the power switch on (IG).

        2. Close the sliding roof to the fully closed position.

        3. Press and hold the TILT UP or SLIDE CLOSE switch to perform the following operations: tilt up → approximately 1 second pause → tilt down → slide open → slide close.

          Note

          Make sure not to release the switch during the initialization. If the switch is released, perform the initialization again.

        4. The initialization is completed.

      2. Procedure B


        1. Turn the power switch on (IG).

        2. Press the TILT UP switch until the sliding roof stops.

          Tech Tips

          If the glass becomes misaligned or does not fully tilt up, perform the following operations:


          1. Operate the SLIDE CLOSE switch until the sliding roof stops moving.

          2. Operate the TILT UP switch until the sliding roof stops moving, then proceed to the next step.

        3. Release the switch.

        4. Press the TILT UP switch for 10 seconds or more to perform the following operations: tilt up → approximately 1 second pause → tilt down → slide open → slide close.

          Note

          Make sure not to release the switch during the initialization. If the switch is released, perform the initialization again.

        5. The initialization is completed.

      3. Procedure C


        1. Turn the power switch on (IG).

        2. Press and hold the SLIDE CLOSE switch to perform the following operations: slide close → move in reverse direction → 10 second pause → slide close.

          Note

          Make sure not to release the switch during the initialization. If the switch is released, perform the initialization again.

        3. After the sliding roof stops in the fully closed position, release the switch.

        4. Perform procedure A.
