Note
•  The blind spot monitoring (BSM) radar aiming procedure stores the radar angles in the blind spot monitoring (BSM) control module based on the forced emission of radar at a SST (Doppler simulator or reflector) and performing aiming based on the induced tolerance with the radar as it is currently installed and reflected from the SST (Doppler simulator or reflector).
•  The blind spot monitoring (BSM) radar aiming is performed when the blind spot monitoring (BSM) control module, blind spot monitoring (BSM) bracket or the rear bumper is replaced.
•  As there are two blind spot monitoring (BSM) control modules, one each on the left and right, radar aiming is performed for each side.
•  Radar aiming cannot be performed correctly if obstructions which interfere with radar emission are stuck on the blind spot monitoring (BSM) control modules or the rear bumper. Perform the following procedure before performing the radar aiming.
―  Verify that there is no water, mud, soiling, sticker adhesion, or repairs done using putty application on the surface of the rear bumper, and that there is no mud, soiling or scratches on the blind spot monitoring (BSM) control modules.

Radar test procedure(doppler simulator)

1.  Empty the vehicle by having all occupants leave the vehicle and remove all the cargo except for the spare tire, jack and tools equipped on the vehicle.

2.  Adjust the air pressure of each tire to the specified value. (See WHEEL AND TIRE SPECIFICATION.)

3.  Park the vehicle on level ground.

Caution
•   If the setting surface height and angle between the vehicle and the SST (reflector) differs, a correct radar test cannot be done. Perform the radar test with the vehicle and SST (reflector) set on level ground.

4.  Verify that there are no obstructions which interfere with radar emissions such as metal objects in the radar emission area shown in the figure.

Caution
•  If the radar test is performed in the shaded area shown in the figure with obstructions such as covered drain gutters in the floor or other metal reflective objects, it could result in the radar test not being performed correctly. Move all obstructions out of the area, and when performing the radar test, do not have personnel standing in the area.

5.  Using the M-MDS, perform a DTC inspection of the BSM control modules and verify that no DTCs are displayed. (See DTC INSPECTION [BLIND SPOT MONITORING (BSM) CONTROL MODULE].)

Note
•  If any DTCs are displayed, perform malfunction repair referring to the applicable DTC troubleshooting. (See DTC TABLE [BLIND SPOT MONITORING (BSM) CONTROL MODULE].)

6.  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 (point A) on the floor surface.

Note
•  The center of the brand emblem indicates the center position of the vehicle.

7.  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 (point B) on the floor surface.

ac5uuw00007411

11.  Mark the points (points D and E) (SST (Doppler simulator) installation reference points) 67.0—67.4 cm {26.4—26.5 in} from point C on the line which runs perpendicular to the vehicle center line (SST (Doppler simulator) installation reference point).

ac5uuw00007412

12.  Pull the connected points D, C and E lines (SST (Doppler simulator) installation line).

Note
•  Verify that the green lamp on the SST (Doppler simulator) unit illuminates.
ac5wzw00010411

14.  Loosen the fixing knobs on the side of the SST (Doppler simulator) and adjust the height of the SST (Doppler simulator) so that the height is between 84—86 cm {33.1—33.8 in} from the floor.

ac5wzw00010412

Caution
•  If the knobs are loosened excessively, the SST (Doppler simulator) could fall and become damaged. Support the SST (Doppler simulator) with one hand while loosening the fixing knobs.
