RADAR SENSOR AIMING [MAZDA RADAR CRUISE CONTROL (MRCC) SYSTEM]

WARNING:

1. Park the vehicle on level ground.

CAUTION:

2. 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:

3. 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:

4. Secure the end of the leveling line over point B.

NOTE:

5. Pull the unsecured end of the leveling line over the vehicle and to the front and adjust it so that it passes over point A.
6. Mark the line (position A) at the point 5 m {16 ft} from point A and in the direction forward of the vehicle.

NOTE:

7. Install the SST (reflector and plum bob) to the SST (tripod).
8. Adjust so that the height of the SST (reflector) from the floor surface is 710 mm {28.0 in}.

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

NOTE:

10. Set the SST (stand) with the SST (plum-bob) and the marking aligned.

NOTE:

11. Visually inspect the surfaces of the radar sensor and the radiator grille ornament for the following:
12. Connect the M-MDS to the DLC-2.

CAUTION:

13. After the vehicle is identified, select the following items from the initialization screen of the M-MDS.
a. Select "Electrical".
b. Select "SBS/MRCC".
c. Select "Reader Aiming".
14. Perform the aiming adjustment following the instructions on the screen.
15. If "Aiming has been unsuccessful." is displayed on the screen, repair according to the error code in the following chart.

CAUTION:
