Solution

1. Preparation

Gather all necessary tools and parts before starting.
Ensure the vehicle is parked on a level surface and the ignition is off.
Wear safety glasses and gloves.

2. Retrieve Trouble Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn on the ignition without starting the engine.
Navigate through the scanner menu to read ABS-related trouble codes.
Document any codes for reference.

3. Inspect Fuses

Locate the fuse box under the dashboard or hood.
Identify the ABS fuse using the diagram on the fuse box cover.
Remove the fuse and check for continuity using a multimeter or by visually inspecting it.
Replace any blown fuses with a new one of the same amperage.

4. Check Wheel Speed Sensors

Lift the vehicle and remove the wheel that corresponds to the ABS light.
Locate the ABS wheel speed sensor near the brake rotor.
Disconnect the sensor connector and inspect for dirt or damage.
Clean the sensor with electrical contact cleaner if necessary, and reconnect it.

5. Check Brake Fluid Level

Open the hood and locate the master cylinder reservoir.
Inspect the brake fluid level; it should be within the "MIN" and "MAX" marks.
If low, add the appropriate brake fluid (DOT 3 or DOT 4 recommended by Honda).

6. Test ABS Pump

Reconnect the OBD-II scanner and clear any trouble codes.
Turn the ignition on and listen for the ABS pump activation sound.
If the pump does not activate, further testing of the ABS module may be required.
