Solution

1. Preparation

Gather tools and parts: OBD-II scanner, socket set, power steering fluid, and safety gloves.
Ensure the vehicle is parked on a level surface with the engine off and the keys removed from the ignition.

2. Check Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level against the dipstick.
If low, add the recommended power steering fluid type (refer to the owner's manual for specifics).
Inspect the fluid for contamination; if dirty, a fluid change may be necessary.

3. Inspect and Tighten Connections

Visually inspect the wiring harness connected to the EPS unit for wear or disconnections.
Use a socket set to tighten any loose bolts on the steering column or steering gear that may contribute to play or instability.

4. Testing Power Steering Pump

Start the engine and turn the steering wheel from side to side to observe any changes in responsiveness.
Use a pressure gauge to measure the output pressure of the power steering pump; it should fall within the manufacturer's specifications.

5. Replace Faulty Components

If the EPS module is faulty, replace it by disconnecting the battery, removing the module, and installing a new one according to the manufacturer's instructions.
Reconnect all electrical connections and ensure they are secure.

6. Final Assembly and Testing

Reassemble any components that were removed during the repair.
Start the vehicle and perform a test drive to ensure steering response is normal and there are no unusual noises.
