Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle's battery to ensure safety while working on electrical systems.

2. Inspect and Replace Power Steering Fluid

Remove the power steering fluid reservoir cap.
Drain old fluid using a fluid extractor or siphon.
Replace with manufacturer-recommended power steering fluid.
Reinstall the reservoir cap and ensure it is secure.

3. Repair or Replace Electrical Components

If loose or corroded connections are found, clean and tighten connections.
If the EPS motor is faulty, disconnect it and remove it from the steering column.
Install a new EPS motor by reversing the removal process.
Connect the electrical harness securely.

4. Reassemble and Test System

Reconnect the battery.
Turn the steering wheel from lock to lock several times to bleed air from the system.
Check for any leaks around the fluid reservoir and the EPS motor connection.
Start the vehicle and monitor the steering feel.
