Radar Test Procedure

  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. Move the vehicle to 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)] .)
    NOTE:
  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.
    NOTE:
    • The center of the brand emblem indicates the center position of the vehicle.

  8. Secure the end of the leveling line over point A,
    NOTE:
    • Use a commercially-available leveling line.

  9. Pull the unsecured end of the leveling line over the vehicle and to the rear and adjust it so that passes over point B.
  10. Mark the line (position C) within the range of 156.8 cm {61.73 in}  from point B and in the direction rearward of the vehicle.

  11. Mark the points (points D and E) (SST (reflector) installation reference points) 170.5 cm {67.13 in}  from point C on the line which runs perpendicular to the vehicle center line (SST (reflector) installation reference point).

  12. Pull the connected points D, C and E lines (SST (reflector) installation line).
  13. Install the SST (reflector and plum bob) to the SST (tripod).
  14. Adjust so that the height of the SST (reflector) from the floor surface is 50 cm {20 in}  .

  15. Level the SST (reflector) by adjusting the leveling bubble on the SST (tripod) so that it is centered on the bubble reference line.

  17. Adjust the reflecting surface of the SST (reflector) so that it faces the radar emission surface (near a rear bumper corner) of BSM control module.
  18. Perform the radar test using the M-MDS.
  19. Connect the M-MDS to the DLC-2.
  20. After vehicle identification, the following can be selected from the M-MDS initialization screen.
    1. "Electrical"
    2. "BSM Radar Test"
  21. Select either the left or right side of the BSM control module.
    NOTE:
    • The radar test can be performed on either the left or right side, however, perform aiming on both the left and right sides.
  22. Verify the M-MDS display.
    • If "TEST PASSED" is displayed
      • Radar test is completed
    • If "TEST FAILED" is displayed
      • Perform an inspection according to the following chart.
Step Inspection Action
1 VERIFY REFLECTOR POSITION 
  • Verify if the reflector installation position is correct.
  • Is the reflector set in the correct position?
 Yes Go to the next step.
No Set the reflector in the correct position and perform the BSM radar test.
2 INSPECT REAR BUMPER 
 Yes Replace the rear bumper and perform the BSM
(See REAR BUMPER REMOVAL/INSTALLATION .)
No Go to the next step.
3 VERIFY IF BSM CONTROL MODULE OR BSM BRACKET IS MIS-INSTALLED AND IF THERE IS DISTORTION TO VEHICLE INSTALLATION SURFACE 
  • Verify whether a BSM control module or BSM bracket has been mis-installed, and if there is distortion to the vehicle installation surface.
  • Is there poor installation or distortion?
 Yes Repair or replace the malfunctioning part and perform the BSM radar test.
No Go to the next step.
4 RE-PERFORM THE BSM RADAR TEST 
  • Perform the BSM radar test.
  • Repeat the M-MDS operation for the BSM radar test 2 or 3 times (Steps 20 to 21).
  • Is "Procedure completed correctly." displayed?
 Yes BSM radar test is completed.
No Replace the BSM control module.
