Solution

1. Preparation

Gather tools and parts required for repairs.
Ensure the vehicle is parked on a flat surface and securely lifted if needed.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Address Diagnostic Trouble Codes

Sub-step 1: Using an OBD-II scanner, clear any existing DTCs after taking note of them for reference.
Sub-step 2: Reconnect the battery and start the vehicle to check if the ABS light reappears.

3. Repair or Replace ABS Components

Sub-step 1: If a faulty ABS sensor is identified, remove the wheel and brake components as necessary to access the sensor.
Sub-step 2: Disconnect the wiring harness and remove the mounting bolt(s) to extract the defective sensor.
Sub-step 3: Install the new ABS sensor, ensuring it is properly aligned and secured, then reconnect the wiring harness.
Sub-step 4: Reassemble any removed components, ensuring all fasteners are torqued to manufacturer specifications.

4. Brake Fluid and System Check

Sub-step 1: If the brake fluid is low or contaminated, drain the old fluid and replace it with new brake fluid that meets Honda specifications (typically DOT 3 or DOT 4).
Sub-step 2: Bleed the brake system to remove air from the lines, ensuring all brakes are fully operational.

5. Final Checks

Sub-step 1: Reconnect the negative battery terminal.
Sub-step 2: Start the vehicle and perform a test drive to ensure the ABS light does not reappear and that braking performance is restored.
