8. Release the SCS short command with the HDS.
9. Turn the steering wheel 90 degrees or more from the center position to left and right position.
10. With the HDS communicating with the BODY ELECTRICAL, test-drive, with only the driver in the vehicle, in a straight line for 98.4 feet (30 m) at 16 mph (25 km/h) or more.
11. Select the AFS from the HDS, and enter the DATA LIST.
12. Make sure the STEERING CENTER LEARN information in the DATA LIST is finished. (If the learn is not completed, repeat the steps 9 and 10.)
