PREPARATION (PROCEDURE 2)

(a) Preparation

  • Digital angle gauge
  • Digital angle gauge attachment
  • Masking tape (To prevent damage)
  • A level

SST: 09989-00020

(b) Confirm levelness of floor surface.

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

NOTICE:

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

HINT:

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) 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.

NOTICE:

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

*b

Level

(4) Press the "ZERO" switch to memorize the zero point (perfectly level).

NOTICE:

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 meter 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. Write the measured values into the following worksheet.

NOTICE:

  • Always position the digital angle gauge as 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.

HINT:

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

Confirmation Area

-

-

(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.

NOTICE:

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.

Worksheet:

(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).

NOTICE:

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.

(c) Prepare the digital angle gauge

(1) Attach the digital angle gauge attachment to the digital angle gauge.

SST: 09989-00020

(2) Attach masking tape to the digital angle gauge attachment.

(d) Remove all luggage from the vehicle.

(e) Adjust the tire inflation pressure to the specified pressure.

SENSOR HEIGHT AND ALIGNMENT INSPECTION (PROCEDURE 3)

HINT:

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

(a) Preparation

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

NOTICE:

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.

NOTICE:

  • 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.
