LANE RECOGNITION CAMERA SENSOR INSTALLATION

Note


  • If the lane departure warning camera bracket is deformed or damaged, replace it together with the windshield glass.

  • If the lane departure warning camera is dropped, replace it with a new one.

  • When replacing the windshield glass of a vehicle equipped with a lane departure warning camera, make sure to use a Lexus genuine part. The lane departure warning camera may not be able to be installed due to a missing bracket or the lane departure alert system may not operate properly due to a difference in the transmissivity or black ceramic border.

        *a Pointed Tip Weight
        *b Mark-off Line

        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 SST (laser radar adjusting reflector).

        SST
        09870-60000   ( 09870-60010, 09870-60020 )

      Note


      • 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 the distance between the target and wall is within 3 m (9.84 ft.).

      • Make sure the shadow of the target is not on the wall as the camera may have a recognition error.

        *1 Line
        *a Approximately 2 m (6.56 ft.)
        *b Point A
        *c Point B

        From the center of the front and rear bumpers (center of the emblems), hang a weight with a pointed tip, and 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 extend the line approximately 2 m (6.56 ft.) beyond the front of the vehicle.

        Tech Tips

        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 (placement point 1) 1120 mm (3.67 ft.) from the front bumper center point A.

        *g Place tape (gray area) approx. 400 mm from point C *h Point G (Placement Point 2)
        *i Point H (Placement Point 3) *j Lane Departure Warning Camera Position

      4. From point C, move 300 mm (11.8 in.) towards the front bumper center point A and mark point D.

      5. From point C, place marking tape at the point 400 mm (1.31 ft.) perpendicular to the line that connects points A and B.

        Note

        Place the tape so that there is plenty of surface area along the perpendicular line.

      6. Using a measuring tape of 500 mm (1.64 ft.) or more, and point D as the center point, draw the part of a 500 mm (1.64 ft.) circle that overlaps the marking tape (line E).

      7. Mark point F at the point where line E and the point that is 400 mm (1.31 ft.) from point C, and is perpendicular to the line that connects point A and B, intersect.

      8. Set the measuring tape from point C to F. Then mark point G (placement point 2) 780 mm (2.56 ft.) from point C (line extending from point C to F).

      9. Set the measuring tape from point F to C. Then mark point H (placement point 3) 780 mm (2.56 ft.) beyond point C.

      10. Set a string between points G and H, and draw a line on the ground (target placement line).

    7. Memorize camera/target position.
