          • The steering wheel will vibrate during torque sensor zero point calibration. Do not touch the steering wheel while it is vibrating or for 2 seconds after it stops.

      18. INITIALIZATION (Pre-crash safety system) (Precautions for Seat Belt Control ECU Replacement)

        The seat belt control ECU operates the pre-crash safety system based on the stored data that informs that the vehicle is LHD or RHD model. LHD or RHD refers to the seating position of the driver, not which side of the road the vehicle is driven on.

        Therefore, when replacing the seat belt control ECU, it is necessary to store the information about whether the vehicle is a LHD or RHD model. This can be performed by following these steps:


        1. Turn the engine switch on (IG).

        2. The PCS warning light comes on for at least 3 seconds after turning the engine switch on (IG). Make sure that the warning light does not remain on.

        3. At this time, the seat belt control ECU receives vehicle configuration (LHD/RHD) information from the gateway ECU and stores it in memory.


          1. Connect the intelligent tester to the DLC3.

          2. Turn the engine switch on (IG).

          3. Turn the tester on.

          4. Enter the following menus: Body / Pre-Crash / Active Test.

          5. Perform Active Test according to the display on the tester.

  • RESET (INITIALIZE) POWER WINDOW REGULATOR MOTOR (Power window control system)

    Note


    • Resetting the power window regulator motor (initializing the pulse sensor) is necessary when the cable is disconnected from the negative (-) battery terminal; when a multiplex network master switch assembly, multiplex network switch assembly, wire harness, power window regulator motor is replaced or removed/installed; or when the fuses are replaced. The auto operation function, jam protection function and remote operation function via the multiplex network master switch assembly do not operate without resetting.

    • Be sure to reset the power window regulator motors using the power window switch on each door because the motors cannot be reset by remote operation using the multiplex network master switch assembly.

    • In order to prevent a large amount of current from flowing in the wires, do not simultaneously reset 2 or more power window regulator motors.

    • If the power window switch is continuously operated for a long time, the power window regulator motor will stop so that no additional load will be applied to the motor. Continuing to operate the switch even after the motor has stopped will cause the switch to blink while restricting the auto up/down function and the remote up/down function. If this happens, reset the motor again after several minutes have passed.

    • When disconnecting the cable from the negative (-) battery terminal, initialize the following system after the cable is reconnected.


    1. Turn the engine switch on (IG).

    2. Halfway open the power window by pressing the power window switch.

    3. Fully pull up the switch until the power window is fully closed and continue to hold the switch for approx. 1 second after the power window is fully closed.

    4. Check that the auto up/down function operates normally.

      If the auto up/down function operates normally, reset operations have been completed at this time. If not normal, follow the steps below.


      1. Disconnect the cable from the negative (-) battery terminal for 10 seconds.

      2. Connect the cable from the negative (-) battery terminal.

      3. Turn the engine switch on (IG).

      4. Halfway open the power window by pressing the power window switch.

      5. If the auto up/down function operates normally, reset operations have been completed at this time.

        If not normal, follow the steps below.

      6. Turn the engine switch on (IG).

      7. Halfway open the power window by pressing the power window switch.

      8. Fully pull up the switch until the power window is fully closed and continue to hold the switch for approx. 12 seconds after the power window is fully closed.

      9. Check that the auto up/down function operates normally.

  • INITIALIZING SLIDING ROOF DRIVE GEAR SUB-ASSEMBLY (Sliding roof system)

    Note

    After the sliding roof drive gear is replaced, the pulse sensor of the sliding roof drive gear needs to be initialized. If a initializing is not executed, the sliding roof cannot be tilted or controlled by turning the switch to position [2] to [8].


    1. Turn the engine switch on (IG).

    2. Press and hold the sliding roof push switch until the following operations are completed:


      1. The sliding roof moves to the tilt fully open position and remains for 1 second.

      2. Tilt down operation starts. After the roof is fully closed, it starts sliding to open.

      3. After the roof slides to the fully open operation, the operation stops and then the roof closes to the fully closed position.

        A0161XEE02
        Switch Condition Sliding Roof Position
        [1] Over stroke position
        [2] Slide fully open position [A]

        [4] Slide stop position [C]
        [5] Slide stop position [D]
        [6] Slide stop position [E]
        [7] Slide stop position [F]
        [8] Slide stop position [G]
        [9] Fully closed position [H]
        [10] Tilt fully open position
        [11]

        Fully closed → comfort stop position

        Open position → fully closed

    3. Check that the operation works normally with auto operation.

    Note


    • If the battery voltage changes during initialization, the sliding roof ECU may not be initialized normally.

    • Do not apply excessive loads to the vehicle during initialization by performing operations such as locking the doors or cranking the engine.

    • Do not turn the engine switch off during initialization.

    • Do not move the vehicle during initialization.

    • Do not apply strong impacts to the vehicle during initialization by performing operations such as closing the doors forcefully.
