Forward Collision-Avoidance Assist (FCA) Radar Alignment

The Forward Collision-Avoidance Assist (FCA) system is designed to prevent a potential collision or reduce its impact when the driver applies the brakes inadequately, late, or not at all to avoid a collision.

For the radar sensor to operate correctly, it must be aligned correctly parallel to the vehicle's direction of travel. For this reason, the radar sensor alignment procedure must be performed each time the sensor is reinstalled or replaced with a new one.

If the sensor alignment procedure is not performed under the conditions specified above, the smart cruise control system may not operate correctly.

Forward Collision-Avoidance Assist (FCA) Radar Alignment

  1. Park the vehicle horizontally on level ground.

  2. Mark the center point of the emblem (A) and the center point on the windshield glass (B).

  3. Attach the SCC calibration laser (SST No.: 09964-C1200) to the tripod (SST No.: 09964-C1300).

  4. Using the SCC calibration reflector [SST No.: 09964-C1100] (A), adjust the wire (D) so that the center point of the emblem (B) and the center point on the ground (C) are perpendicular to each other.

  5. Install the vertical/horizontal laser [SST No.: 09964-C1200] (A) at a distance of more than 4.2 m (12.5 ft) from the front of the vehicle.

  6. Align the vertical laser line with (A) and (B) using the vertical/horizontal laser (C) [SST No.: 09964-C1200].

  7. Mark (C) at a distance of 1.0–3.8 m (3.3–12.5 ft) from (A) in front of the vehicle.

  8. Remove the SCC calibration laser [SST No.: 09964-C1200] (B) from the tripod [SST No.: 09964-C1300] (A).

  9. Install the reflector [SST No.: 09964-C1100] (B) on the stand [SST No.: 09964-C1300] (A).

  10. Align the vertical weight (B) of the SCC calibration reflector [SST No.: 09964-C1100] (A) with point (C).

  11. Using the level vial (B) of the stand [SST No.: 09964-C1300] (A), set the reflector horizontally.

  12. Set the height of the SCC calibration reflector [SST No.: 09964-C1100] (A) to 330 mm (13.0 in.).

  13. Visually check the radar sensor and front bumper surface again for any objects.

  14. Connect the KDS to the vehicle DLC and start the sensor alignment.

  15. After selecting the correct vehicle model, select "Radar Sensor Alignment" from the auxiliary functions in the KDS menu.

  16. Perform the sensor alignment by following the instructions shown on the KDS monitor.

  17. If the sensor alignment fails, check the alignment conditions. Turn the ignition off, then repeat the sensor alignment procedure.

Inspection

Forward Collision-Avoidance Assist (FCA) System Malfunction Check Procedures:

  1. Inspect the front bumper appearance and accident history (bumper appearance, vehicle service history, and bumper replacement history).

    → If the vehicle has been involved in a collision, the FCA mounting bracket may be bent.

  2. Check whether the radar sensor cover on the bumper is contaminated.

    → If the cover is dirty, the FCA may be obstructed by foreign substances during operation.

  3. After starting the engine, check the FCA warning message on the instrument panel and the DTC. (Refer to the DTC chart.)

  4. After starting the engine, stop the vehicle for more than 5 seconds.

    → If the system initialization (yaw rate sensor offset compensation) is not completed, the FCA will not operate.
