Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Disconnect the negative battery terminal to prevent any electrical shorts.

2. Addressing Error Codes

If any error codes were retrieved from the OBD-II scanner, note them down.
Clear the codes and take the vehicle for a short test drive to see if the ABS light returns.

3. Replace Faulty Components

ABS Wheel Speed Sensors:
- Remove the wheel and tire to access the wheel speed sensor.
- Disconnect the sensor wiring harness.
- Remove the retaining bolt and the sensor from its mounting point.
- Install the new sensor in reverse order, ensuring it is securely fastened and connected.
Brake Fluid Replacement:
- With the vehicle raised, remove the master cylinder cap.
- Use a turkey baster to extract old brake fluid from the reservoir.
- Refill with fresh brake fluid (DOT 3 or DOT 4 as specified).
- Bleed the brakes to remove any air from the system.

4. Check and Replace Fuses

Locate the fuse box and refer to the diagram for the ABS fuse.
Remove the fuse and check for continuity with a multimeter.
If blown, replace it with a fuse of the same amperage.

5. Reconnect Battery

Reconnect the negative battery terminal and ensure it is tight.
Recheck all connections and components for security.
