Solution

1. Preparation

Gather tools and parts.
Disconnect the battery to prevent electric shock.
Ensure the vehicle is on a flat surface and secured with wheel chocks.

2. Inspect and Replace Fuse/Relay

Locate the EPS fuse in the fuse box.
- Tools Required: Fuse puller or pliers.
Remove the fuse and inspect it; replace if blown.
Check the EPS relay for proper operation and replace if faulty.

3. Fluid Check and Replacement

Remove the power steering reservoir cap.
Check the fluid level; if low, top it off with the recommended power steering fluid (typically Honda PSF).
If fluid is dirty or contaminated, drain and replace it:
1. Disconnect the return hose from the power steering pump.
2. Allow the old fluid to drain into a container.
3. Reconnect the hose and refill the reservoir with new fluid.

4. Repair Wiring and Connectors

Visually inspect the wiring harness connected to the EPS motor.
Repair or replace damaged wires or corroded connectors as needed.

5. Replace EPS Motor (if necessary)

If diagnostics indicate a faulty EPS motor:
1. Remove the steering column cover.
2. Disconnect the EPS motor connector.
3. Unbolt the EPS motor from its mounting bracket.
4. Install the new EPS motor, aligning it properly.
5. Reconnect the wiring harness.

6. Calibration

If a steering angle sensor calibration is required:
- Use the manufacturer’s diagnostic tool to perform the calibration procedure as per specifications.
