Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.
Ensure the vehicle is securely lifted if necessary.

2. Inspect and Replace EPS Fuse

Locate the fuse box (refer to the owner’s manual for exact location).
Remove the cover and identify the EPS fuse.
Use a fuse puller or needle-nose pliers to remove the fuse.
Inspect for any signs of damage and replace with a fuse of the same amperage.

3. Check and Replace Power Steering Fluid

Locate the power steering reservoir.
Remove the cap and check the fluid level; if low, fill with the manufacturer-recommended power steering fluid.
If the fluid is dark or contaminated, drain and replace completely:
- Disconnect the return line and drain the old fluid into a container.
- Reconnect the line and refill the reservoir with new fluid.

4. Inspect Wiring and Connectors

Visually check the wiring harness connected to the EPS motor and control module.
Look for frayed wires, corrosion, or loose connections.
Repair or replace any damaged wiring or connectors.

5. Test EPS Motor and Control Module

Using a multimeter, check the voltage at the EPS motor while turning the steering wheel.
If the voltage is not within specifications, the motor or control module may need replacement.
Follow manufacturer specifications for any replacement procedures.

6. Reassemble and Reconnect Battery

After completing repairs, ensure all components are properly reassembled.
Reconnect the negative battery terminal.
Clear any diagnostic codes using the OBD-II scanner.
