Solution

1. Preparation

Gather tools and equipment: OBD-II scanner, socket set, torque wrench, and any specific tools for the steering system.
Ensure the vehicle is parked on a level surface with the ignition off.

2. Inspect Steering System Components

Sub-steps:
1. Visually inspect the power steering fluid level in the reservoir. Top up if necessary with the correct fluid type as specified in the owner's manual.
2. Check for leaks in the power steering system, including hoses and the steering rack.
3. Inspect the condition of the steering column and joints for wear or damage.

3. Test Steering Assist Motor

Sub-steps:
1. Disconnect the battery to ensure safety before working on electrical components.
2. Locate the steering assist motor (usually mounted on or near the steering column).
3. Using a multimeter, test the motor for proper voltage and continuity according to specifications found in the service manual.
4. If the motor is faulty, replace it with a new unit.

4. Reconnect and Program

Sub-steps:
1. Reconnect the battery and clear any stored codes using the OBD-II scanner.
2. If necessary, perform any required steering angle calibration via the scanner, as per the service manual.
3. Test the steering system again to confirm proper function.
