Radar test procedure (doppler simulator): Notes

  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:
  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 6.45-6.75 m {254-265 in} from point A and in the direction rearward of the vehicle.

  12. Pull the connected points D, C and E lines (SST (Doppler simulator) installation line).
  13. Insert the SST (AC-DC converter) into the side of the SST (Doppler simulator) and turn on the power.

    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.
  15. Level the SST (Doppler simulator) by turning the SST (Doppler simulator) adjustment knobs and adjust so that the leveling bubble is centered on the reference line.

  19. Remove the SST (plum bob).
  20. Perform the radar test using the M-MDS.
  21. Connect the M-MDS (IDS) to DLC-2.
  22. After the vehicle is identified, select the following items from the initial screen of the M-MDS.
    1. "Electrical"
    2. "BSM test"
    3. "Aiming by using Doppler"
  23. Select either the left or right rear BSM control module and perform the radar test according to the instructions on the M-MDS screen.
  24. Select either the left or right blind spot monitoring (BSM) control module and perform the radar test according to the instructions on the M-MDS screen.
  25. Verify the M-MDS display.
    • If "Procedure completed successfully" is displayed
      • The radar aiming procedure is complete
    • If "This test found error." Or, "Procedure not completed successfully" is displayed.
      • Perform an inspection according to the following table.
    Step Inspection Action
    1 DOPPLER SIMULATOR POSITION SET VERIFICATION
    • Verify if the Doppler simulator installation position is correct.
    • Is the Doppler simulator set in the correct position?
    		 Yes Go to the next step.
    No Set the Doppler simulator in the correct position and perform the blind spot monitoring (BSM) radar aiming.
    2 INSPECT REAR BUMPER
    • Remove the rear bumper. (See REAR BUMPER REMOVAL/INSTALLATION .)
    • Perform the blind spot monitoring (BSM) radar aiming procedure.
    • Is "Procedure completed successfully." displayed?
    		 Yes Replace the rear bumper and perform the BSM radar aiming procedure.
    (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 aiming procedure.
    No Go to the next step.
    4 REPEAT REAR MONITORING RADAR AIMING
    • Perform the blind spot monitoring (BSM) radar aiming procedure.
