Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to prevent any electrical short circuits.

2. Check and Replace Fuses

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Inspect the VSA fuse; if blown, replace it with a fuse of the same amperage.
Reconnect the battery.

3. Inspect and Clean Wheel Speed Sensors

Raise the vehicle securely on jack stands.
Remove the wheel to access the wheel speed sensor.
Clean the sensor and mounting area with brake cleaner to remove any debris.
Check the wiring and connector for damage or corrosion; repair or replace as needed.

4. Test and Replace Brake Fluid

Check the brake fluid reservoir for the correct fluid level; refill with Honda Genuine Brake Fluid if low.
If fluid appears contaminated, perform a brake fluid flush to replace it entirely.

5. Replace Brake Pedal Switch

Locate the brake pedal switch near the brake pedal assembly.
Disconnect the electrical connector and remove the switch.
Install the new switch and reconnect the electrical connector.

6. Recheck ABS Module

Inspect the ABS module connections for corrosion or damage.
If issues persist, consider replacing the ABS module as a last resort.
