Solution

1. Preparation

Gather the necessary tools and parts.
Disconnect the negative terminal of the battery to ensure safety while working on electrical components.

2. Check Power Steering Fluid

Locate the power steering reservoir.
Remove the cap and check fluid level; add Honda power steering fluid if low.
Inspect the fluid condition; if it appears contaminated, proceed to replace it.

3. Replace Power Steering Fluid (if necessary)

Use a turkey baster to remove old fluid from the reservoir.
Refill with new Honda power steering fluid.
Start the engine and turn the steering wheel from lock to lock to circulate new fluid.

4. Inspect and Replace Fuse

Locate the fuse box (typically under the dashboard or in the engine compartment).
Identify the EPS fuse using the fuse diagram on the cover.
Remove the fuse and inspect it; replace it with a new fuse of the same amperage if blown.

5. Repair or Replace EPS Motor

If the EPS motor is found to be faulty during testing, disconnect the electrical connectors and remove the motor.
Install a new EPS motor by reversing the removal process, ensuring all connectors are secured.
