Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the ignition off.
Disconnect the battery to prevent any electrical shorts.

2. Inspect the Steering System

Visual Inspection:
- Check the steering column for any physical damages or loose connections.
- Inspect the electric power steering motor for signs of wear or corrosion.

3. Test Power Supply

Voltage Check:
- Reconnect the battery after inspection.
- Turn the ignition to the "ON" position without starting the engine.
- Use a multimeter to check the voltage at the power steering motor connector. It should typically read between 12 to 14 volts.

4. Check Steering Angle Sensor

Sensor Testing:
- Locate the steering angle sensor (usually found near the steering wheel).
- Use a multimeter to verify the sensor’s output voltage while turning the steering wheel. Confirm that it varies appropriately with the wheel's position.

5. Functional Test

Road Test:
- Start the vehicle and take it for a short drive.
- Pay attention to the steering feel at various speeds and during tight turns.
- Listen for any abnormal noises or feedback from the steering system.
