Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the negative battery terminal to prevent any electrical issues.

2. Inspect and Replace ABS Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Remove the cover and identify the ABS fuse using the diagram on the fuse box.
Remove the fuse and inspect it. If it is blown, replace it with a new fuse of the same amperage.

3. Check Brake Fluid

Open the hood and locate the brake fluid reservoir.
Check the brake fluid level; if low, top up with the manufacturer-recommended brake fluid (Honda DOT 3 or DOT 4).
Inspect the fluid for contamination; if dirty, a brake fluid flush may be necessary.

4. Inspect ABS Wheel Speed Sensors

Lift the vehicle and remove the front and rear wheels as needed for access.
Locate the ABS wheel speed sensors on each wheel hub.
Inspect the wiring and connectors for damage or corrosion.
Clean any dirt or debris from the sensor and the tone ring it reads.

5. Test ABS Module and Pump

Reconnect the battery terminal and use an OBD-II scanner to check for any new error codes.
If codes persist, engage the ABS pump by using a scan tool that can activate the ABS system.
Listen for the pump operation and check for any leaks or unusual noises.
