TARGET ADJUSTMENT(FLAT SURFACE TARGET)
PROCEDURE
1. PREPARATION FOR MILLIMETER WAVE RADAR SENSOR ASSEMBLY ADJUSTMENT
(a) Park the vehicle on a level surface where the area in front of the vehicle shown in the illustration is free of metal objects.
*a | 2.5 m (8.2 ft.) |
*b | 2 m (6.6 ft.) |
Do not place any metal objects in this area | |
Do not place metal objects with a height of more than 50 mm (1.97 in.) in this area |
HINT:
Metal objects with a height of 50 mm (1.97 in.) or less placed within the area shown in the illustration will not affect the adjustment.
(b) Check the levelness of the ground.
(1) Check the levelness of the ground at the 3 points shown in the illustration.
*a | 3 m (9.84 ft.) |
Levelness Check Point |
(2) Place the level on each levelness check point and check that the air bubble of the level is centered.
(c) Adjust the tire inflation pressure to the specified pressure.

(d) Clean the front emblem or millimeter wave radar sensor assembly.
(e) Visually inspect the front of the vehicle.
HINT:
Confirm that there is no damage or deformation.
(f) Visually inspect the front bumper assembly, radiator grill and stays.
HINT:
Confirm that there is no damage or deformation.
2. MILLIMETER WAVE RADAR SENSOR ASSEMBLY VERTICALLY AND HORIZONTALLY
(a) Adjust SST (flat surface target) height.
*a | SST (Flat Surface Target) |
*b | SST (Stand) |
(1) Check that SST (flat surface target) has no damage or deformation.
SST: 09870-60100
SST: 09870-60110
(2) Check that SST (flat surface target) is assembled correctly.
(3) Check that SST (flat surface target) has no looseness or wobble.
(4) Loosen the top and bottom handles of SST (stand), and while checking the included scale, adjust the height of SST (flat surface target) as shown in the illustration so that its height reference line is at the same height as the millimeter wave radar sensor assembly, then re-tighten the top and bottom handles. HINT:
Reference Value: 690 mm (2.26 ft.) |
|
(b) Hang a weight with a pointed tip from the center of the rear emblem, and mark the rear center point of the vehicle (point A) on the ground.
*a | String | *b | Weight |
*c | Center | - | - |
HINT:
Lightly flick the string with your fingers several times to confirm that the string is perpendicular to the ground.
(c) Hang a weight with a pointed tip from the center of the front emblem, and mark the front center point of the vehicle (point B) on the ground.
*a | String | *b | Weight |
*c | Center | - | - |
HINT:
Lightly flick the string with your fingers several times to confirm that the string is perpendicular to the ground.
(d) When using a laser line marker:
NOTICE:
Do not look directly into the laser beam.
(1) Press the laser mode button on the laser line marker to activate the laser line emitters. | |
(2) Align the laser beam ground marking point (cross portion) with point B. |
|
(3) Align the center of the target panel with point A, and set the target panel so that it faces forward.
*a | Center Line | *b | Target Panel |
(4) Adjust the position of the laser line marker so that the laser beam is aligned with the center line of the target panel.
(5) Extend a tape measure at least 1500 mm (4.92 ft.) in length from point B, and set the tape measure in place. |
|
(6) Mark point C at a distance of 1500 mm (4.92 ft.) from point B, and apply a 300 mm (11.81 in.) piece of tape alongside the tape measure so that the tape extends 150 mm (5.91 in.) to the front and rear of point C. |
|
(e) When not using a laser line marker:
(1) Using tape and a string, create a line that connects point B to point A and extends at least 1500 mm (4.92 ft.) beyond the front center point of the vehicle.
*a | String | *b | Tape |
*c | 1500 mm (4.92 ft.) | - | - |
HINT:
(2) Mark point C (SST (flat surface target) placement position) at a position 1500 mm (4.92 ft.) from point B.
(3) Position SST (flat surface target) so that it is aligned with the target position line and the mark-off line is aligned with point C as shown in the illustration.
*a | SST (Stand) | *b | Mark-off Line |
*c | Reference Line | - | - |
(f) Front Beam Axis Adjustment:
NOTICE:
(1) Connect the GTS to the DLC3.
(2) Turn the power switch on (IG).
(3) Turn the GTS on.
(4) Enter the following menus: Body Electrical / Front Radar Sensor / Utility / Front Beam Axis Adjustment.
