PREPARATION (PROCEDURE 2)

1. Preparation

   
   

   • Digital angle gauge

   • Digital angle gauge attachment

   • Masking tape (To prevent damage)

   • A level

   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.

      Tip:

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

   2. Turn on the digital angle gauge.

   3. 

      *a

      Digital Angle Gauge

      *b

      Level

      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.

   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. 

      Confirmation Area

      -

      -

      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.

      Tip:

      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. Figure 1. Worksheet:

      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.

   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. 

      Table 1.

      *1	After calibrating, displays 90° when turned on its side
      *2	Calibrating

      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. 

   Table 2.

SENSOR HEIGHT AND ALIGNMENT INSPECTION (PROCEDURE 3)

1. Preparation

   
   

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

      Note:

      If the bumper, grill 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.

   Sensor height and alignment inspection

3. 

   Table 3.

   *1	Corner of Sensor
   *2	Sensor Height

   Measure the installation height of the sensors.

   Table 4. 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.)

   Table 5. 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.)

   Table 6. 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.

   Tip:

   Use the center of the sensor as the measuring point.

4. 

   Table 7.

   *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. 

      Table 9. 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°.

      Tip:
      

      • 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.

      Table 8. 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°

      Table 10. 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.
