Solution

1. Preparation

Gather all required tools and parts.
Ensure the vehicle is on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; it should be within the marked range.
If low, add the recommended fluid type (typically Honda Power Steering Fluid).
If the fluid looks dirty or contaminated, proceed to flush the system.

3. Inspect and Replace Components

Inspect the steering angle sensor:
- Locate the sensor on the steering column.
- Check for loose connectors; reconnect if necessary.
- If the sensor is damaged, remove it by unbolting and replacing it with a new one.
Inspect the EPS motor:
- Check the motor for any signs of wear or damage.
- If faulty, remove the EPS motor assembly and replace it with a new unit following the manufacturer’s specifications.

4. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any stored error codes.
Start the vehicle and check if the steering assist warning light remains off.
