Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery terminal to ensure safety.

2. Inspect and Replace Wheel Speed Sensors

Sub-steps:
- Locate the wheel speed sensors at each wheel hub.
- Clean the area around each sensor to prevent dirt from entering during removal.
- Disconnect the electrical connector from the sensor.
- Remove the sensor using the appropriate socket or wrench.
- Install the new sensor by reversing the removal process, ensuring it is seated properly and the connector is secure.

3. Check and Replace ABS Fuse

Sub-steps:
- Locate the fuse box under the dashboard or hood.
- Identify the ABS fuse using the fuse diagram.
- Remove the fuse and check for continuity using a multimeter.
- If the fuse is blown, replace it with one of the same amperage.

4. Inspect and Add Brake Fluid

Sub-steps:
- Locate the master cylinder reservoir.
- Check the brake fluid level; if low, add new brake fluid that meets Honda specifications (DOT 3 or DOT 4).
- Close the reservoir cap securely after adding fluid.
