Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative battery terminal to ensure safety during repairs.

2. Inspect and Clean ABS Sensors

Remove the wheel covering the ABS sensor.
Clean the sensor and the tone ring with a brake cleaner to remove any debris.
Reinstall the wheel and torque the lug nuts to the manufacturer’s specifications.

3. Replace Faulty Wheel Speed Sensors (if required)

If the diagnostic indicated a faulty sensor, remove the damaged sensor by unscrewing it from its housing.
Install the new wheel speed sensor and secure it in place.
Reconnect the electrical connector ensuring a snug fit.

4. Check and Replace Brake Fluid (if required)

Open the brake fluid reservoir cap.
If the fluid is contaminated or low, use a brake fluid siphon to remove old fluid.
Refill with the appropriate type of brake fluid (DOT 3 or DOT 4 as specified by Honda).
Replace the reservoir cap securely.

5. Clear Error Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear the error codes from the ABS system.
Test the vehicle to ensure the ABS light remains off after repairs.
