BLIND SPOT MONITORING (BSM) RADAR TEST

Introduction

- The BSM radar test examines the reflectivity from the SST (reflector) by forcibly emitting radar to the SST.
- One BSM control module is installed on the left and right sides. Perform the radar test for each of them.
- Perform the radar test on level ground. The correct test results cannot be obtained if the vehicle and reflector are set at different heights or different angles.
- A radar test cannot be performed correctly if obstructions which interfere with radar emitting adhere to the BSM control module or the rear bumper. Perform the following procedure before performing the radar test.

- Verify that there is no water or dirt adhering to the radar emitting surface of the BSM control module and the rear bumper.
- Verify that there is no problem with the radar emitting surface of the BSM control module and the rear bumper such as dirt, application of metallic stickers, or repairs using putty application.

- Perform the DTC inspection for the BSM using the M-MDS and verify that no DTCs are displayed.

- If any DTCs are displayed, perform troubleshooting according to the corresponding DTC inspection. Blind Spot Monitoring (BSM) - DTC Table

Radar Test Procedure

1. Remove any occupants and unload cargo from the cabin and trunk compartment so that the vehicle is in an unloaded condition.

2. Adjust the air pressure of each tire to the specified value.

3. Park the vehicle on a flat, level surface.

4. Verify that there is no obstruction within a 3,500 mm {137.8 in} radius from the BSM control module as shown in the figure.






CAUTION:
- If an obstruction such as a drain lid or a person is within a 3,500 mm {137.8 in} radius from the BSM control module, it will interfere with radar emitting and skew the radar test results. Remove any obstruction which is within a 3,500 mm {137.8 in} radius from the BSM control module.

5. Adjust the SST (plum-bob) so that it is aligned with the center of the brand emblem, determine the center position at the front of the vehicle, and mark the center position on the floor surface.






NOTE:
- The center of the brand emblem indicates the center position at the front of the vehicle.
- A commercially-available plum-bob (weight: 150 g {5.29 oz}) can be substituted for the SST.

6. Adjust the SST (plum-bob) so that it is aligned with the center of the brand emblem, determine the center position at the rear of the vehicle, and mark the center position on the floor surface.






NOTE:
- The center of the brand emblem indicates the center position at the front of the vehicle.
- A commercially-available plum-bob (weight: 150 g {5.29 oz}) can be substituted for the SST.

7. Position the leveling line over the marked positions at the front and rear of the vehicle, and then mark the position on the floor surface 1,540 mm ± 8 mm {60.63 in ± 0.3 in} from the vehicle rear.

CAUTION:
- If the center position at the vehicle rear is set first, the leveling line could be misaligned. Determine the center position at the vehicle front first, then set the center position at the vehicle rear.

NOTE:
- Use a commercially-available leveling line.





8. Mark the position on the floor where a right angle is formed by the lines which cross at the point 1,540 mm ± 8 mm {60.63 in ± 0.3 in} from the vehicle rear and the point 1,780 mm ± 8 mm {70.08 in ± 0.3 in} from the vehicle side which is perpendicular to the vehicle's center line.






9. Set the SST (reflector) installation surface level using the bubble level built into the SST (tripod).






10. Install the SSTs (reflector and plum-bob) to the SST (tripod) and adjust the height of the reflector at its center to 580 mm ± 8 mm {22.8 in ± 0.3 in}.






11. Verify visually that the reflecting surface of the reflector is facing the BSM control module, and position the SST (tripod) so that the SST (plum-bob) is positioned over the marked position.






NOTE:
- The BSM control module installation position is indicated in the figure.





12. Perform the BSM radar test according to the screen instructions using the M-MDS.

13. Connect the M-MDS to DLC-2.






14. After the vehicle is identified, select the following items from the initialization screen of the M-MDS.

- When using the IDS (laptop PC)

- Select the "Electrical".
- Select the "BSM Radar Test".

- When using the PDS (Pocket PC)

- Select the "All Tests and Calibrations".
- Select the "BSM Radar Test".

15. Perform the procedure according to the directions on the screen.

16. Verify the M-MDS display.

- "TEST PASSED" is displayed

- Radar is normal.

- "TEST FAILED" is displayed

- Perform the inspection according to the following table.
