Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery terminal for safety.

2. Inspect and Replace Fuse

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Remove the cover and identify the power steering fuse using the diagram on the cover or the vehicle's manual.
Use a multimeter to check for continuity. Replace the fuse if it is blown.

3. Check Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; it should be between the minimum and maximum marks.
If low, top off with the recommended power steering fluid (consult the owner's manual for specifications).

4. Inspect Electric Power Steering Motor

Locate the electric power steering motor, typically mounted on the steering column.
Check for loose or damaged wiring connectors.
If necessary, remove the motor by unscrewing it from the mount and visually inspecting it for any physical damage.

5. Test and Replace Steering Angle Sensor (if needed)

Locate the steering angle sensor, typically integrated into the steering column.
Disconnect the sensor and use a multimeter to test its resistance and voltage output.
If the readings are outside specifications, replace the sensor with a new one.

6. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and check for proper operation of the power steering system.
Ensure the steering assist is functioning correctly during a test drive.
