  2. PREPARATION (PROCEDURE 2)


    1. Preparation


      • Digital angle gauge

      • Digital angle gauge attachment

      • Masking tape (To prevent damage)

      • A level

      SST
      09989-00020
    2. Confirm levelness of floor surface.


      1. Place a bubble level on a level surface and confirm that the bubble is centered.

        Note

        Make sure that there is no gravel, sand, etc., and that the surface is not undulating.

        Tech Tips

        By adjusting the direction of the bubble level, it is possible to find a position where the bubble is centered.

        B006AT7
      2. Turn on the digital angle gauge.

      3. Place the digital angle gauge in the same location and direction as that of the bubble level where the levelness of the surface was confirmed.

        Note

        Confirm that the location and direction of the digital angle gauge is exactly the same as that of the bubble level.

        *a Digital Angle Gauge *b Level
      4. Press the "ZERO" switch to memorize the zero point (perfectly level).

        Note

        Make sure that the digital angle gauge does not move when pressing the switch. If the digital angle gauge moves when the switch is pressed, an incorrect zero point may be memorized and it will not be possible to accurately check for levelness.

      5. Using the digital angle gauge in which the zero point (perfectly level) has been memorized, measure the angle of the floor surface at the 4 positions at the front of the vehicle and the 4 positions at the rear of the vehicle as shown in the illustration.

        Note


        • Always position the digital angle gauge in the direction shown in the illustration.

        • Make sure that there is no gravel, sand, etc., and that the floor surface is not undulating.

        • When measuring the angle of the floor surface, avoid uneven areas such as joints between tiles.

        Tech Tips

        If necessary, the digital angle gauge can be placed anywhere within the specified area when measuring the angle of the floor surface for positions A, C, F and H.

      6. Using the following worksheet, calculate the average of the measurements taken at the 4 positions in front of the vehicle, and calculate the average of the measurements taken at the 4 positions behind the vehicle. Confirm that the front measurement average and the rear measurement average are not more than approximately 0.37 degrees. Also, confirm that the front measurement average and the rear measurement average is less than 0.2 degrees.

        Note

        If the front measurement average and the rear measurement average are more than approximately 0.37 degrees or the difference between the front measurement average and the rear measurement average is 0.2 degrees or more, choose another work area as it is not possible to accurately check the installation angle of the sensors.

        Figure 1. Worksheet:

        B006F43E01
      7. Average the front measurement average and the rear measurement average, then round the answer to 1 decimal place (E.g. 0.0927 degrees is rounded to 0.1 degrees) to obtain the floor surface inclination value.

      8. Calibrate the digital angle gauge

        Adjust the angle of the digital angle gauge until it reads the same value of the floor surface inclination, then press the "ZERO" switch to memorize the zero point (level with floor surface).

        Note

        Before pressing the "ZERO" switch, confirm that the digital angle gauge reading is positive if the floor angle inclination is positive, and negative if the floor angle inclination is negative.

  3. SENSOR HEIGHT AND ALIGNMENT INSPECTION (PROCEDURE 3)

    Tech Tips

    Check if the installation angle of each ultrasonic sensor is appropriate.


    1. Preparation


      1. Visually check that the bumper, grille and ultrasonic sensors are installed properly and are not damaged.

        Note

        If the bumper, grille or any ultrasonic sensor is not installed correctly, the calibration may not be able to be completed.

      2. Check the tire pressures and adjust them if necessary.

        Click here

        Note


        • Ensure that the vehicle is level in an area with no wind.

        • Do not lean on the vehicle.

        • Do not do anything that may affect the level of the vehicle during the calibration, such as getting in or out of the vehicle, or adding or removing luggage.

      3. Adjust standard vehicle height.


    2. Sensor height and alignment inspection

      B006C1NE01
    3. B006ANIE01
      *1 Corner of Sensor
      *2 Sensor Height

      Measure the installation height of the sensors.

      Standard Height (except Sport Package) (Front Bumper):
      Sensor Location Sensor Height
      Front Center Ultrasonic Sensor 430.0 to 497.7 mm (16.9 to 19.6 in.)
      Front Corner Ultrasonic Sensor 550 to 617.9 mm (21.7 to 24.3 in.)
      Standard Height (for Sport Package) (Front Bumper):
      Sensor Location Sensor Height
      Front Center Ultrasonic Sensor 443.2 to 501.0 mm (17.4 to 19.7 in.)
      Front Corner Ultrasonic Sensor 550.0 to 617.9 mm (21.7 to 24.3 in.)
      Standard Height (Rear Bumper):
      Sensor Location Sensor Height
      Rear Center Ultrasonic Sensor 519.3 to 593.8 mm (20.4 to 23.4 in.)
      Rear Corner Ultrasonic Sensor 519.3 to 593.7 mm (20.4 to 23.4 in.)

      Note

      If the installation height of a sensor is not as specified, it may not be possible to measure the sensor angles correctly. If so, unload the vehicle and measure the installation height of the sensors again.

      Tech Tips

      Use the center of the sensor as the measuring point.

    4. B006GCQE01
      *1 Digital Angle Gauge
      *2 Digital Angle Gauge Attachment
      *3 Ultrasonic Sensor

      Using the digital angle gauge, measure the angle of each sensor.


      1. Measure the angle of the front sensors as shown in the illustration.

        Note

        Ensure that the digital angle gauge is flush with the face of the sensor.

      2. Measure the angle of the rear sensors.

        Note

        Ensure that the digital angle gauge is flush with the face of the sensor.

      3. B006G7GE03
        For example
        *1 Digital angle gauge
        *2 Horizontal line
        *3 Ultrasonic Sensor
        *4 Digital angle gauge attachment

        Confirm that the angles of the sensors are as specified.

        Note

        The sensor angle is the measured sensor angle subtracted from 90°.

        Tech Tips


        • The digital angle gauge should indicate 90° when turned on its side.

        • If the face of the sensor is tilted upwards, the sensor angle will be positive.

        Standard Height (Front Bumper):
        Sensor Location Installation Angle
        Front Center Ultrasonic Sensor 0.02 to 6.89°
        Front Corner Ultrasonic Sensor 3.32 to 10.19°
        Standard Height (Rear Bumper):
        Sensor Location Installation Angle
        Rear Center Ultrasonic Sensor -1.16 to 5.71°
        Rear Corner Ultrasonic Sensor -0.72 to 6.15°
      4. If the angle or height of the sensors is not as specified, confirm that the installation is correct and then perform the inspection again.
