Distance Sensor: Adjustments

Millimeter Wave Radar Aiming

Special Tools Required

- Radar Aimer Set 070AJ-SDA0101

Prepare the items shown:

- HDS
- Level (commercially available)





- Tape measure and scale
- Felt-tip pen
- Tape

NOTE: If the millimeter wave radar is removed or replaced, or if a millimeter wave radar aiming error occurs, aim the millimeter wave radar. Incomplete aiming, an aiming error, or dust or dirt on the radar surface causes the ACC indicator to come on.

- Millimeter wave radar aiming incomplete: DTC 107
- Millimeter wave radar aiming error: DTC 63
- Millimeter wave radar or front radar cover surface is contaminated with dust, dirt, ice, or snow: DTC 105

Before Aiming:

- Aiming the millimeter wave radar requires the HDS.
- Clean the surface of the millimeter wave radar.
- Make sure the vehicle has no aftermarket suspension.
- Make sure all the tire sizes are correct and that their pressure are correct.
- Make sure the fuel tank is full.
- Remove all baggage from the vehicle except the spare tire and the tool kit.
- Make sure the steering wheel is straight ahead, and do not turn it after setting the vehicle.
- Shift transmission lever into P, and apply the parking brake.
- Make sure the upper grille and the front bumper are installed correctly.
- Park the vehicle on level ground in a wide open space to avoid misadjusting caused by reflecting objects. The space needs to be 32.8 ft (10 m) in front, 13.1 ft (4 m) in width and 4.9 ft (1.5 m) in height.
- If NO TARGET is not indicated even when there are no objects for 33 ft (10 m) in front vehicle, check for reflecting objects in front of the vehicle.

NOTE: When the millimeter wave radar is adjusted on ground that has more than 1 degree of horizontal slope (drainage slope), the vertical aiming cannot be adjusted correctly. Check the levelness of the ground, and adjust the angle of millimeter wave radar to be parallel to that of the ground, lay a ruler (at least 12'') or other flat straight object on the ground and put the level on top to confirm the levelness of the ground.

Vertical Aiming

NOTE: When the millimeter wave radar is adjusted on ground that has more than 1 degree of horizontal slope (drainage slope), the vertical aiming cannot be adjusted correctly. Check the levelness of the ground, and adjust the angle of millimeter wave radar to be parallel to that of the ground, lay a ruler (at least 12'') or other flat straight object on the ground and put the level on top to confirm the levelness of the ground.

1. Remove the upper grille cover Upper Grille Replacement.

2. Put the level (A) (commercially available) on the aiming pad (B) of the millimeter wave radar.





3. Turn the vertical adjusting bolt (C) on the driver's side with a screwdriver, and adjust the angle of millimeter wave radar so that the air bubble in the level is centered.

Horizontal Aiming

1. Park the vehicle on level ground with at least this much open space around it: 32.8 ft (10 m) in front, 13.1 ft (4 m) in width, and 4.9 ft (1.5 m) in height.





2. Make sure there are no reflecting objects or anything in this range.

3. Check the tire pressures, and adjust the pressures to the specified value if need.

4. Put a person or an object equivalent to the driver's weight in the driver's seat.

Setting the Distance between the Target and the Vehicle

NOTE: When marking on the floor, use suitable tape to mark the exact locations.

5. Adjust the tip of the height rod (A) on the target to the center of the front radar cover (B).










6. Place the centering stand under the rear tow hook, then mark the floor at the centerline of the tool.






7. At the front of the vehicle, slide the gas strut holder and the cord through the slot in the centering stand, then slide the strut to the rear of the vehicle.






8. Position the gas strut holder between the rear tow hook and the mark on the floor.






9. Place the centering stand under the hole in the front lift pad.






10. With the target and the height rod aligned with the cord, move the target out in front of the vehicle until the cord is fully extended (16.5 ft, 5 m). Position the cord at the centerline of the centering stand.






11. Contact the HDS to the data link connector (A).






12. Turn the ignition switch to ON (II).

13. Check for DTCs with the HDS.

NOTE: If DTC 61 or DTC 62 is indicated, troubleshoot the indicated DTC first.

14. Start the engine.

15. Press the ACC switch (A) ON.






16. Select ADAPTIVE CRUISE CONTROL (ACC) from DRIVING SUPPORT menu. Select RADAR AIMING from ADJUSTMENT menu, the MID will indicate the number "4" on its display for 2 seconds then display "NO TARGET".






17. Make sure the MID indicates "NO TARGET" on its display.

NOTE: When the radar is aimed correctly the MID indicates "NO TARGET". If this is not indicated there is an unwanted radar reflection in front of the vehicle in the range of the radar.






18. Confirm the result of the horizontal auto aiming following the on screen instructions of the HDS.

NOTE: The result of all auto aiming can be confirmed by the HDS, by the figure and words displayed on the MID, or by the brake lights illuminating. When the figure is not in the range, 100±2 or a tone is sounded by the vehicle when the aiming point is out of specification, or when the brake lights do not come on, the auto aiming is not completed correctly. If DTC 120, 121,122, 123, or 124 is indicated, the aiming target is not set correctly. Reset the aiming target.





19. After adjustment, confirm the MID display and the brake lights illuminating, and finalize the horizontal aiming (End the aiming process on the HDS).

20. After aiming, clear the DTCs with the HDS.

DTCs (if the aiming is incomplete)

NOTE: If the aiming is incomplete, the MID indicates a DTC. The ACC unit does not store the DTC, and you cannot read the DTCs with the HDS, so note the DTC before cycling the ignition key.
