Circuit/System Verification

With scan tool installed, clear the DTCs. Turn the steering wheel through its full range and back to straight ahead to center the steering angle sensor. Using a scan tool, observe the Steering Wheel Position parameter changes smoothly while turning steering wheel through the entire range. Correlate zero reading with wheels in the straight ahead position. Drive the vehicle through a variety of maneuvers turning to the left, right and then straight ahead at a speed greater than 20 km/h (13 mph).

• If the DTC did not set as a current DTC see diagnostic aids.
