MILLIMETER WAVE RADAR SENSOR INSTALLATION

Engage the 10 claws and install the front bumper assembly.

Install the 2 clips and screw.

Install the 8 screws.

Install the screw.

Install the 2 pin hold clips.

Install the 2 radiator grille protectors.

Install the cool air intake duct seal with the 9 clips.

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   ( 09870-60010 )

   09870-60040

   Tech Tips

   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.

Place the reflector.

1. Hang the string (with a weight) from the center of the vehicle rear emblem. Mark the vehicle rear center point on the ground. Repeat the same procedure for the front of the vehicle.

2. 

   Set one end of the 10 m (32.82 ft.) string on the vehicle rear center point. Run the string over the vehicle front center point to a position 5 m (16.41 ft.) beyond the vehicle front center point, as shown in the illustration. Mark the 5 m (16.41 ft.) position.

3. Using the 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.

   

   Note

   Perform the operation as precisely as possible.

Adjust the radar beam axis.

1. 

   Connect the intelligent tester to the DLC3.

2. Turn the engine switch on (IG).

3. Turn the intelligent tester main switch on, and turn the cruise control main switch on.

   Tech Tips

   If an error message is displayed on the screen, initialization of the distance control ECU may not be completed. Initialize the distance control ECU Click here.

   

   

Check and adjust the horizontal direction of the radar sensor.

1. Check that the divergence of the radar beam axis is 0° .

   Standard
   0° (Both right and left)
   If the divergence is not as specified, use a screwdriver to adjust bolt B until the divergence of the radar beam axis is 0°.

2. 

   Based on the measured divergence of the beam axis, turn and adjust bolt B for horizontal adjustment of the millimeter wave radar sensor using a screwdriver.

   Adjustment Direction Adjustment Procedure Adjustment Angle Horizontal adjustment Right direction: Turn bolt B to positive (+) side Left direction: Turn bolt B to negative (-) side For every 18.6 rotations of adjustment bolt, sensor moves about 1°

   Tech Tips

   
   

   • If "LEFT SIDE: 1.0°" is displayed, the divergence is 1.0° to the left . Turn bolt B approximately 3 turns to the negative (-) side.

   • If the value does not change to 0°, it is possible that the sensor is aiming at something different. Reconfirm that there are no reflective materials in the surrounding area.

3. 

   Reset the radar sensor's driving learning values. Prepare a piece of metal that can block radio waves, such as aluminum foil. Cover the radar sensor's right half with the aluminum foil for 10 seconds.

   Note

   Be sure to keep the reflector in place and make sure that there is nothing between the sensor's left half and the reflector.

   Tech Tips

   When the reset is completed, the buzzer sounds for 10 seconds.

4. Disconnect the intelligent tester from the DLC3.

Recheck and readjust the vertical direction of the radar sensor.

1. 

   Set a level on the radar sensor's level rack.

2. 

   Check that the air bubble is within the red frame on the level.

   OK
   The air bubble is within the red frame on the level.
   If the bubble is not within the red frame, use a screwdriver to adjust bolt A until the air bubble is within the red frame.

   Tech Tips

   
   

   • The adjustable range within the red frame on the level is +/- 0.2°.

   • The target angle is +0.2° (upward angle of 0.2°).

Prepare the vehicle:

• Place the vehicle in a location that is dark enough to clearly observe the cutoff line. The cutoff line is a distinct line, below which light from the fog lights can be observed and above which it cannot.

• Place the vehicle at a 90° angle to the wall.

• Create a 25 m (82 ft.) distance between the vehicle (fog light bulb center) and the wall.

• Make sure that the vehicle is on a level surface.

• Position the front wheels straight ahead.

• Bounce the vehicle up and down several times to settle the suspension.

  Note

  A distance of 25 m (82 ft.) between the vehicle (fog light bulb center) and the wall is necessary for proper aim adjustment. If sufficient space is not available, secure a distance of exactly 3 m (9.84 ft.) to allow for checking and adjustment of fog light aim. (The size of the target zone will change with the distance, so follow the instructions in the illustration.)

Set the screen as shown in the illustration.

Draw base lines (H, V LH, and V RH lines) on the screen as shown in the illustration.

1. H Line (Fog light height):

   Draw a horizontal line across the screen so that it passes through the center marks. The H line should be at the same height as the fog light bulb center marks of the fog lights.

2. V LH Line, V RH Line (Center mark positions of left-hand (LH) and right-hand (RH) fog lights):

   Draw two vertical lines so that they intersect the H line at each center mark aligned with the center of the fog light bulbs.

Turn on the fog light and check if the cutoff line falls within the specified area in the following illustration.

Adjust the aim vertically:

Adjust the aim of each fog light to the specified range by turning each aiming screw with a screwdriver.
