Solution

1. Preparation

Gather tools and safety equipment.
Disconnect the battery to prevent electrical shock.
Ensure the vehicle is on a flat surface and securely supported.

2. Inspect and Replace EPS Fuse

Locate the fuse box; consult the owner’s manual for the exact location.
Remove the cover and identify the EPS fuse.
Use a fuse puller to carefully remove the fuse.
Inspect the fuse for continuity; replace with a new fuse of the same amperage if faulty.

3. Check and Top Up Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level against the dipstick markings.
If low, add the recommended type of power steering fluid (typically Honda PSF fluid) until it reaches the proper level.

4. Inspect Wiring and Connectors

Visually inspect the wiring harness leading to the EPS motor for frays or damage.
Ensure all connectors are securely attached and free of corrosion.
If any issues are found, repair or replace the damaged components.

5. Test Electrical Supply

Reconnect the battery.
Using a multimeter, check the voltage at the EPS motor connector while the ignition is on.
Ensure the voltage is within manufacturer specifications (usually around 12V); if not, further electrical diagnosis may be needed.

6. Reassemble and Clear Codes

Reattach any components removed during inspection.
Use the OBD-II scanner to clear any fault codes.
Reconnect the battery and ensure all systems are functioning properly.
