CRUISE CONTROL: OBJECT RECOGNITION CAMERA: ADJUSTMENT
HINT
If the object recognition camera sensor is replaced or removed/installed, or the toe-in is adjusted, perform the object recognition camera sensor and object recognition camera ECU adjustments.
1. ADJUST OBJECT RECOGNITION CAMERA
NOTICE:
* Make sure there are no black and white patterned objects in front of the vehicle.
* Perform the measurement in a place with no wind, and make sure there is a distance of 1.5 m (4.92 ft.) or more in front of the vehicle and that the surface is level with no obstacles.
* Check that there are no reflective materials in the surroundings or on the ground within a 3 m (9.84 ft.) or more x 3 m (9.84 ft.) or more area in front of the vehicle.
* Perform the inspection in a bright area.
* Turn the taillights on.
* Do not turn the headlights on.
(a) Beam axis learning preparation
(1) Move the vehicle to a level surface.
(2) Make sure the engine oil in the vehicle is at the specified amount.
(3) Make sure the engine coolant in the vehicle is at the specified amount.
(4) Make sure the fuel tank is full.
(5) Make sure the spare tire is in the vehicle.
(6) Make sure the standard tools are in the vehicle.
(7) Make sure nobody is in the vehicle.
(8) Make sure no extra loads are in the vehicle.
(9) Adjust the tire pressures to the specified pressure.
(10) Set the height control switch to normal.
(11) Clean the front glass.
(12) If the lens of the object recognition camera sensor is dirty, apply a small amount of lens cleaner to a clean, soft cloth and clean the lens.
(b) Perform height control sensor adjustment
(1) Perform height control sensor adjustment Adjustments.
NOTICE:
Perform this procedure as accurately as possible.
(c) Perform the front wheel alignment adjustment
(1) for 2WD:
Perform the front wheel alignment adjustment Front Wheel Alignment.
NOTICE:
Perform this procedure as accurately as possible.
(2) for AWD:
Perform the front wheel alignment adjustment Front Wheel Alignment.
NOTICE:
Perform this procedure as accurately as possible.
(d) Perform the rear wheel alignment adjustment
(1) Perform the rear wheel alignment adjustment Rear Wheel Alignment.
NOTICE:
* Perform this procedure as accurately as possible.
* Press the height control switch, change the vehicle height to HIGH and return it to NORM. Then repeat.
(e) Target sheet creation
(1) Print or copy the illustration below. Check that the dimensions are +/-5 mm of the ones in the table below.
Dimension:
NOTICE:
* Make sure that the black areas of the target sheets are not glossy.
* Make sure that the borders of the black and white areas on the target sheets are straight, and are not warped or blurry.
If the print or copy's dimensions are not as specified, adjust settings and reprint or recopy the illustration so that the print or copy's dimensions are as specified.
(f) Target sheet attachment
(1) Place the prepared target sheet on a piece of cardboard of the same size with the black area on the top right as shown in the illustration. Then use double-sided tape to fix the target sheet in place.
NOTICE:
Do not attach reflective tape such as scotch tape, etc. to the target face as this may affect target recognition.
(2) Hang a weight with a pointed tip from the center of the target sheet. Then with double-sided tape, attach the target sheet to the reflector so that the weight aligns with the mark-off line of the SST (laser radar adjusting reflector).
SST : 09870-60000
09870-60010
09870-60020
NOTICE:
* Perform this procedure as accurately as possible.
* Attach the target sheet so that it is horizontal with the ground.
(3) Move the reflector up and down to position the center of the target at the height shown in the illustration, and the fix it in place.
Dimension A:
1270 mm (50.0 in.)
SST : 09870-60000
09870-60010
09870-60020
NOTICE:
Perform this procedure as accurately as possible.
(g) Target placement point measurement
NOTICE:
* Do not place black and white patterned objects near the target.
* Face the vehicle toward a wall with no patterns, or make sure the background behind the target has no patterns.
* Perform this procedure as accurately as possible.
* Do not place reflective materials in the area behind the target.
* Make sure there are no patterns on the wall behind the target.
* Make sure the distance between the target and wall is within 3 m (9.84 ft.).
* Make sure the target's shadow is not on the wall as the camera may have a recognition error.
(1) From the center of the front and back bumpers (center of the emblems), hang a weight with a pointed tip, and then mark the front bumper center point A and the rear bumper center point B on the ground.
(2) Draw a line that connects points A and B, and then extend the line approximately 2 m (6.56 ft.) beyond the front of the vehicle.
HINT
Secure the end of a string to point B. Then hold the other end of the string approximately 2 m (6.56 ft.) in front of the vehicle and move it to the left or right to align the string with point A to make a straight line.
(3) Mark point C 990 mm (39.0 in.) from the front bumper center point A (placement point 1).
(4) From point C, move 700 mm (27.6 in.) towards the front bumper center point A and mark point D.
(5) From point C, place marking tape at the point 700 mm (27.6 in.) perpendicular to the line that connects points A and B.
NOTICE:
Place the tape so that there is plenty of surface area along the perpendicular line.
(6) Using measuring tape {5 m (16.4 ft. or more)} and point D as the center point, draw the part of a 990 mm (39.0 in.) circle that overlaps the marking tape (line E).
(7) Mark point F where the following intersect: 1) from point C, the point that is 700 mm (27.6 in.) perpendicular from the line that connects point A and B; and 2) line E.
(8) Set the measuring tape from point C to F. Then mark point G 740 mm (29.1 in.) from point C (line extending from point C to F) (placement point 2).
(9) Set measuring tape from point F to C. Then mark point H 740 mm (29.1 in.) beyond point C (placement point 3).
(10) Set a string between points G and H, and then draw a line on the ground (target placement line).
(h) Object recognition camera sensor height measurement
NOTICE:
* Do not place black and white patterned objects near the target.
* Face the vehicle toward a wall with no patterns, or make sure the background behind the target has no patterns.
* Perform this procedure as accurately as possible.
* Do not place reflective materials in the area behind the target.
* Make sure there are no patterns on the wall behind the target.
* Make sure the distance between the target and wall is within 3 m (9.84 ft.).
* Make sure the target's shadow is not on the wall, as the camera may have a recognition error.
(1) Measure the distance (X mm or in.) from the ground to point H for the front left wheel arch.
(2) Measure the distance (Y mm or in.) from the ground to point H for the front right wheel arch.
