Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Fuses

Sub-steps:
1. Locate the fuse box (usually under the dashboard or in the engine compartment).
2. Refer to the fuse diagram to identify the ABS fuse.
3. Remove the fuse and check for any signs of damage; replace with a new fuse of the same amperage if necessary.

3. Inspect and Replace Wheel Speed Sensors

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the wheel to access the wheel speed sensor.
3. Disconnect the sensor's electrical connector.
4. Remove the sensor from its mounting location.
5. Install the new wheel speed sensor in reverse order, ensuring it is securely fastened.
6. Reconnect the electrical connector and reinstall the wheel.

4. Brake Fluid and Line Inspection

Sub-steps:
1. Check the brake fluid reservoir; if low, top off with the manufacturer-recommended brake fluid.
2. Inspect brake lines for any visible leaks or damage; replace any damaged sections.
3. Bleed the brake system if brake fluid was added or lines were replaced.

5. Reconnect Battery and Clear Codes

Sub-steps:
1. Reconnect the negative battery terminal.
2. Use the OBD-II scanner to clear any stored ABS error codes.
3. Start the vehicle and check if the ABS light remains off.
