Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, fluid pump.
Disconnect the negative battery terminal to prevent electrical shorts.
Ensure the vehicle is parked on a level surface with the ignition off.

2. Inspect and Replace the EPS Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Remove the EPS fuse using a fuse puller.
Inspect the fuse for continuity; replace if blown with a fuse of the same amperage.

3. Check and Replace EPS Relay

Locate the EPS relay in the fuse box.
Remove the relay and test it for continuity using a multimeter.
Replace the relay if it is faulty with a new relay of the same specifications.

4. Inspect and Repair Wiring Connections

Visually inspect the wiring harness connected to the EPS motor and control module.
Look for signs of wear, corrosion, or loose connections.
Repair or replace any damaged wiring or connectors as necessary.

5. Fluid Maintenance

If the power steering fluid is low or contaminated, flush the system.
Use the manufacturer-recommended power steering fluid.
Fill the reservoir to the appropriate level and bleed the system of any air by turning the steering wheel from lock to lock with the engine running.

6. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and check for any warning lights on the dashboard.
Test the steering system for proper operation.
