NOTE:
The millimeter wave radar must be re-aimed if the millimeter wave radar is removed or replaced. The ACC indicator comes on if the aiming process is not completed correctly. If DTCs are indicated, do the indicated DTC's troubleshooting first. If the DTCs are not repaired, you cannot complete the millimeter wave radar aiming procedure:
?
Two kinds of aiming procedures involving the use of HDS must be performed for the millimeter wave radar to be re-aimed: vertical aiming and horizontal aiming.
?
The millimeter wave radar has a self-diagnosis function and if the mounting angle of the millimeter wave radar is outside of the horizontal auto-aiming range, it sends the failure information to the multipurpose camera unit.
?
Millimeter Wave Radar Aiming Incomplete: DTC P2583-54
?
Millimeter Wave Radar Aiming Error: DTC P2583-64
Park the vehicle on level ground in a wide open space to avoid errors caused by reflecting objects. The space needs to be 10 m (33 ft) in front, 4 m (13 ft) in width and 1.5 m (4.9 ft) in height.

Have the driver sit in the driver's seat.
When marking on the floor, use suitable tape to mark the exact locations.

3. Millimeter Wave Radar - Vertical Radar Aim
NOTE:
Aiming the millimeter wave radar requires the HDS.
Clean the surface of the millimeter wave radar.
Make sure the steering wheel is pointed straight ahead, and do not turn it after setting up the vehicle.


Marking of the Target Position
1.
Pull the string (A) forward 4,000 mm (157.48 in) from point B1, then mark a new point D1. Repeat this step for the opposite front wheel, and mark a point D2 on the floor.
2.
Stretch a string (A) between point D1 and point D2, and tape both ends of the string on the floor. Mark a new point Z1 where the string crosses with the center line (B).
3.
Mark a new point Z2 on the right side of point Z1 on the string (A) as shown.
Target offset value (B)
4-door
296 mm (11.65 in)
2-door
314 mm (12.36 in)
4.
Adjust the tip of the stand set (A) so that it is aligned with the lower edge of the millimeter wave radar cover (B) or the front bumper lower grille (2-door) as shown.
5.
Draw a line (Y) on the pole of the stand set as shown.
6.
Draw lines (Y1), (Y2) and (Y3) on the pole (A) of the stand set as shown.

7.
Connect the HDS to the data link connector (DLC) (A).
8.
Turn the vehicle to the ON mode.
9.
Make sure the HDS communicates with the vehicle and the multipurpose camera unit. If it does not communicate, go to the DLC circuit troubleshooting.
10.
Check for DTCs with the HDS.

NOTE: If DTC P2583-54 or DTC P2583-64 is indicated, troubleshoot the indicated DTC first.
11.
In the DRIVING SUPPORT MENU, select INTEGRATED DRIVER SUPPORT SYSTEM, then ADJUSTMENT, then select Radar Aiming on the HDS.
12.
Press "Enter" to start vertical aiming on the HDS.
13.
The MID will indicate the number 3 on the display for a few seconds. Then follow the instructions on the HDS.
NOTE: If an error message appears on the HDS, there is an unwanted radar reflection in front of the vehicle in the range of the radar. If available, stack tires about 1.5 m (4.9 ft) in height in front of either the immovable object, such as a pole, or in front of any object causing the unwanted reflections. The tires will block the radar reflections. If the error message appears again, move the vehicle to a different location.
14.
Turn the corner reflector (A) of the stand set to the vehicle.
15.
Place the stand set on the mark (Z2).
16.
Set the corner reflector (A) of the stand set to the position of Y1, then press "Enter" on the HDS.
17.
Set the corner reflector (A) of the stand set to the position of Y2, then press "Enter" on the HDS.
18.
Set the corner reflector (A) of the stand set to the position of Y3, then press "Enter" on the HDS.
19.
The HDS will display the current angle of the millimeter radar. If the angle is not within the specified angle of 00.1 degrees, place a screwdriver (A) in the adjusting bolt (B), then turn the screwdriver either clockwise or counterclockwise until the angle is set to 00.1 degrees. Watch the HDS display while performing the adjustment as the values will change.

Angle shown on the HDS display
Rotate the screwdriver as follows
More than ?0.1 °
Rotate the screwdriver clockwise
Less than ?0.1 °
Rotate the screwdriver counterclockwise
NOTE:
While reading the angle on the HDS, do not stand or pass in between the millimeter wave radar and the stand set.
If the HDS indicates a value of more than ?2.0 ° or less than ?2.0 °, do the following:
?
Turn the adjusting bolt as indicated in the chart below.
?
Turn the vehicle to the OFF (LOCK) mode to abort the vertical aiming.
?
Restart the vertical aiming procedure from step 8.
?
If the HDS still indicates a value that is more than ?2.0 ° or less than ?2.0 °, inspect the millimeter wave radar mounting position.
Angle shown on the HDS display
Rotate the screwdriver as follows
More than ?2.0 °
Rotate the screwdriver 15 1/2 times clockwise
Less than ?2.0 °
Rotate the screwdriver 15 1/2 times counterclockwise
20.
If the MID indicates a vertical aiming failure code, refer to the table below. Then repeat the vertical aiming procedure.
Vertical Aiming Failure Codes (if the vertical aiming is incomplete)
NOTE: If the vertical aiming is incomplete, the MID indicates a vertical aiming failure code. The multipurpose camera unit does not store the vertical aiming failure code and cannot be read with the HDS, so note the code before turning the vehicle to the OFF (LOCK) mode.
Aiming failure code
(on the MID)
Cause
How to solve
120
Two or more aiming targets exist.
Remove all reflective objects except the correct special tools, and repeat the aiming procedure.
122
The distance of the aiming target is out of specification.
Set the distance to the aiming target 3,850?4,150 mm (151.57?163.39 in), and repeat the aiming procedure.
124
The angle of the millimeter wave radar is exceeding the adjustable range or the height of the aiming target is out of the specified range.
Inspect and adjust the millimeter wave radar mounting position or the height of the aiming target to the specified height and repeat the aiming procedure.
125
There is no aiming target.
Reset the aiming target at the correct position, and repeat the aiming procedure.
21.
After adjustment, press "Enter", then go to the horizontal aiming.

4. Millimeter Wave Radar - Horizontal Radar Aim
1.
Move the stand set from the front of the vehicle, then start the horizontal aiming.
2.
The MID will indicate the number 4 on the display for a few seconds, then display NO TARGET.
3.
Make sure the MID indicates NO TARGET on its display.
NOTE: If NO TARGET is not indicated, there is an unwanted radar reflection in front of the vehicle in the range of the radar. If available, stack tires about 1.5 m (4.9 ft) in height in front of either the immovable object, such as a pole, or in front of any object causing the unwanted reflections. The tires will block the radar reflections. Make sure "NO TARGET" appears on the MID. If it still does not appear, move the vehicle to a different location until "NO TARGET" appears on the MID.
4.
Turn the corner reflector (A) of the stand set to the vehicle.
5.
Place the stand set on the mark (Z2).
NOTE: When the stand set is placed, the MID will display ''RADAR OK'' with code 100.
 
6.
Set the corner reflector (A) of the stand set to the position of Y2, then press "Enter" on the HDS.
7.
Confirm "The radar aiming has been completed." on the HDS. After adjustment, confirm the MID display, and finalize the horizontal aiming (end the aiming process on the HDS).
NOTE: The result of horizontal radar aiming can be confirmed by the HDS or the MID.
When the target is out of range, the horizontal radar aiming is not complete. The MID will display ''NO TARGET''. If the aiming failure code 120, 122, 123, or 124 is indicated, the aiming target is not set correctly.
Inspect the millimeter wave radar mounting for bent or damaged parts. Verify the vertical aiming, and reset the aiming target if necessary.
The aiming information obtained is stored in the millimeter wave radar.
Horizontal Aiming Failure Codes (if the horizontal aiming is incomplete)
NOTE: If the horizontal aiming is incomplete, the MID indicates a horizontal aiming failure code. The multipurpose camera unit does not store the horizontal aiming failure code and cannot be read with the HDS, so note the code before turning the vehicle to the OFF (LOCK) mode.
