17. ADJUST MILLIMETER WAVE RADAR SENSOR ASSEMBLY
CAUTION: Exposure to radio frequency emissions is hazardous to your health. It is hazardous to your health to be within 20 cm (7.9 in.) of the device's radio frequency aperture.
NOTE:
- This device complies with FCC radio frequency emission regulations.
- Perform measurements on a level surface.
- Make sure that no large pieces of metal are within a 10 m (32.81 ft.) x 14 m (45.93 ft.) area in front of the vehicle. If possible, the surrounding area should also be free of large metal objects.
a. Before adjusting the radar beam axis, prepare the vehicle as follows.
1. Check the tire pressure and adjust it if necessary.
2. Remove all excess weight from the vehicle (luggage, heavy objects, etc.).
b. w/ Air suspension:
Adjust the vehicle's height to the standard height.
c. Check and adjust the vertical direction of the radar sensor.
1. Remove dust, oil and foreign matter from the radar sensor's level rack.
2. Set a level on the radar sensor's level rack.
3. Check that the level's air bubble is within the red frame.
OK: Level's air bubble is within red frame. If the bubble is not within the red frame, use a hexagon wrench to adjust screw A until the level's air bubble is within the red frame.
HINT:
- The adjustable range within the level's red frame is ±0.2°.
- The target angle is +0.2° (upward angle of 0.2°).
d. Adjust the reflector height.
1. Adjust the reflector so that the center of the SST reflector is the same height as the millimeter wave radar sensor.
SST 09870- 60000
HINT: Prepare a 10 m (32.81 ft.) string, a string with a sharp-pointed weight (plumb bob), and a 5 m (16.41 ft.) tape measure.
e. Place the reflector.
1. Hang the string (with weight) from the center of the vehicle rear's emblem. Mark the vehicle rear's center point on the ground. Repeat for the front of the vehicle.
2. Set one end of the 10 m (32.82 ft.) string on the vehicle rear's center point. Run the string over the vehicle front's center point to a position 5 m (16.41 ft.) beyond the vehicle front's center point, as shown in the illustration. Mark the 5 m (16.41 ft.) position.
3. Using a tape measure, measure 12 mm (0.47 in.) to the left of the 5 m (16.41 ft.) position. Place the reflector at that position.
