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. (See DTC TABLE [BLIND SPOT MONITORING (BSM)] .)

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.

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.

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.

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.
