          *1 Tire Pressure Warning Valve and Transmitter *2 Transmitter ID (7 Digit Number)
    2. REGISTER TRANSMITTER ID

      Note


      • When performing ID registration for the 2nd tire set, make sure that ID registration has been completed for the main tire set.

      • If ID registration for the main tire set has not been completed, it is not possible to perform ID registration for the 2nd tire set.

      • When performing ID registration for the 2nd tire set, place the tires and wheels of the 2nd tire set and main tire set close to the vehicle (less than 10 m (32.8 ft.) away from the vehicle).

        Tech Tips

        When registering an ID on the 2nd tire set, a tire and wheel which have an ID from the main tire set are necessary to also perform ID certification for the main tire set. If ID certification is not performed on the main tire set, DTC C2126/26 is stored by the tire pressure warning ECU and receiver.

      • When using the 2nd tire set or switching from the 2nd tire set to the main tire set after registration for the 2nd tire set is completed, switch to the appropriate set of IDs after installing the tires and wheels.

      Tech Tips


      • The previously registered IDs will be cleared from memory when the registration is completed.

      • If the ID registration step is not completed within 300 seconds, ID registration will be canceled.

      • In order to perform ID registration for the 2nd set of tires, select "2nd Set" on the display screen.


      1. Set the air pressure of all tires to the specified value(s).

    3. CONFIRMATION OF TRANSMITTER ID REGISTRATION

      Note


      • It may take up to a few minutes to update the tire pressure data. If the values are not displayed after a few minutes, perform troubleshooting according to the inspection procedure for DTCs C2121/21 to C2124/24.

      • If the IDs have not been registered, DTC C2171/71 is stored in the tire pressure warning ECU and receiver after 3 minutes or more.

      • If normal pressure values are displayed, the IDs have been registered correctly.

      • If the tire pressure values are not displayed after a few minutes, the IDs may be incorrect or the system may have a malfunction.

      • After all IDs are registered, DTC C2126/26 is stored in the tire pressure warning ECU and receiver and the tire pressure warning light blinks for 1 minute and then illuminates. When the tire pressure warning ECU and receiver successfully receives signals from all the transmitters whose IDs are stored in the ECU, DTC C2126/26 is cleared and the tire pressure warning light goes off.


      1. When checking the registration of IDs on the sub-transmitter (2nd) side, operate the steering pad switch assembly and switch to the sub-transmitter (2nd) side.

      2. Enter the following menus: Chassis / Tire Pressure Monitor / Data List.

      6. Check that the tire pressure data has been updated, and then adjust the tire pressures to the specified pressure, operate the steering pad switch assembly and perform initialization.

  14. INITIALIZATION RELATED TO TIRE PRESSURE WARNING SYSTEM

    Note


    • Initialization can be confirmed through the tire pressure warning light.

    • The order in which the data is received is random.

    • If the signals from all the wheels are received, initialization is completed.

    • Initialization is completed when the Data List "ID Tire Inflation Pressure" display shows the correct pressures.

    • Initialization is normally completed within a few minutes.

    • It may take up to a few minutes until the values are displayed. If the values are not displayed after a few minutes, perform troubleshooting according to the inspection procedure for DTCs C2121/21 to C2124/24.

    • If initialization has not been completed successfully, DTC C2177/77 is stored after a vehicle speed of 37 km/h (23 mph) or more continues for 20 minutes or more.

    • During test mode (signal check mode), the system will not change to initialization mode even if the initialization procedure is performed.

    • When answer-back is displayed for the ID switching function, the system will not change to initialization mode even if the initialization procedure is performed.

          Tech Tips


          • Recognition code registration is necessary when replacing the door control transmitter or the door control receiver.

          • Add mode is used to register new recognition codes while still retaining codes already registered. This mode is used when a new transmitter is added. If the number of registered codes exceeds 4, the previously registered codes will be cleared in order, starting from the first registered code.

          • Rewrite mode is used to clear all the previously registered recognition codes in order to register new recognition codes. This mode is used when the transmitter or the door control receiver is replaced with a new one.

          • Confirmation mode is used to confirm how many recognition codes have already been registered before registering any additional recognition codes.

          • Prohibition mode is used to clear all the registered codes and disables the wireless door lock function. This mode is used when the transmitter is lost.

          • All of the following registration procedures must be performed in order and in a continuous sequence.

        2. REGISTER RECOGNITION CODE (USING INTELLIGENT TESTER)

      Note


      • When disconnecting the sliding roof drive gear, the sliding roof drive gear requires initialization. If a reset is not executed, the following functions do not operate: auto operation and jam protection operation.

      • Use the map light (roof sunshade switch) to perform the initialization.

      Tech Tips

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


      1. Turn the ignition switch to ON.

      2. Operate the roof sunshade so that it moves to the fully open position.

      3. Push and hold the open switch on the map light (roof sunshade switch) until initialization is complete.

        Tech Tips


        • When it is detected that the motor is locked (the roof sunshade has moved further to the rear than the fully open position), the detected position is set as the position information.

        • After the motor locks, the final part of the initialization will start and the roof sunshade will continue to move until it reaches the fully open position, where it then stops.

  • INITIALIZE POWER WINDOW CONTROL SYSTEM (POWER WINDOW REGULATOR [ALL DOORS])

    CAUTION:

    When the door window regulator is reinstalled or replaced, the power window control system must be initialized. Functions such as auto up/down, jam protection and key-off do not operate if the initialization is not performed.

    Tech Tips

    When the battery is replaced, it is not necessary to initialize the door window regulator.

    Note



    1. Fully close the window by fully pulling the power window switch, and hold the switch for 1 second or more after the window is fully closed to reset the glass position.

  • UTILITY RELATED TO AUTOMATIC HIGH BEAM SYSTEM

    Note


    Tech Tips

    The pre-crash safety city sensor recognizes the white lines in relation to the vehicle on the basis of coordinates derived from the traveling direction of the vehicle. These coordinates differ for each vehicle depending on the tolerance and installation position of the pre-crash safety city sensor to the vehicle. Therefore, pre-crash safety city sensor beam axis adjustment must be performed individually for each vehicle.


    1. RECOGNITION CAMERA/TARGET POSITION MEMORY


      1. Before performing "Recognition Camera Axis Adjust", store the recognition camera position information, target position information and vehicle information in the pre-crash safety city sensor.

        Tech Tips

        For pre-crash safety city sensor adjustment procedures.

    2. RECOGNITION CAMERA AXIS ADJUST


      1. After storing the "Recognition Camera/Target Position Memory", further calibrate the stored data.

        Tech Tips


        • Since there is an error in the internal data derived from the stored recognition camera position (horizontal and vertical coordinates, etc.), calibrating the internal data captured in the recognition camera improves the recognition sensitivity of the recognition camera.

        • For pre-crash safety city sensor adjustment procedures.

    3. ENTER CONTROL MODE


      1. When reproducing the problem symptom of the pre-crash safety system function, do not operate the pre-crash brake and only operate the warning (operations and buzzer sounding).

        Tech Tips

        When reproducing the problem symptom of the pre-crash safety system function, actually operating the pre-crash brake would be dangerous. To avoid this, when triggering operation of the pre-crash safety system function, do not operate the pre-crash brake and only operate the warning.

    4. PCS IMAGE RECORD SETTING


      1. Clear the PCS image information stored in the pre-crash safety city sensor.

    5. HISTORY CLEAR


      1. When the history data status is "ON", clear the history.
