Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and safety goggles.
Ensure the vehicle is parked on a flat surface and the ignition is off.

2. Check and Replace Fuses

Sub-steps:
1. Locate the fuse box under the dashboard or in the engine compartment.
2. Identify the ABS fuse using the diagram on the cover.
3. Remove the fuse using a fuse puller and check for continuity with a multimeter.
4. Replace any blown fuses with the same amperage rating.

3. Inspect and Clean Wheel Speed Sensors

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Locate the wheel speed sensors on each wheel hub.
3. Disconnect the sensor harness and remove the sensor using a socket set.
4. Clean any debris or dirt from the sensor and the mounting area.
5. Reinstall the sensor and reconnect the harness securely.

4. Check Brake Fluid Level

Sub-steps:
1. Open the hood and locate the brake master cylinder reservoir.
2. Inspect the fluid level; if low, add the manufacturer-recommended brake fluid.
3. Check for any leaks around brake lines and connections.

5. Clear Codes and Test Drive

Sub-steps:
1. Reconnect the OBD-II scanner and clear any stored ABS error codes.
2. Start the vehicle and check if the ABS light remains off.
3. Conduct a test drive to ensure the ABS system operates correctly.
