Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent any electrical issues.

2. Scan and Clear Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Retrieve ABS fault codes and note any specific codes displayed.
Clear the fault codes using the scanner.
Reconnect the battery terminal after clearing codes.

3. Inspect ABS Wheel Speed Sensors

Locate the ABS wheel speed sensors at each wheel hub.
Remove any debris or dirt obstructing the sensor's view of the wheel.
Check the sensor harness for damage and ensure all connections are secure.

4. Check ABS Fuses

Locate the fuse box (usually found under the dashboard or hood).
Identify the ABS fuse using the diagram on the fuse box cover.
Use a multimeter to test the fuse for continuity; replace if it is blown.

5. Inspect Brake Fluid Level

Check the brake fluid reservoir for proper fluid levels.
If low, top off with the manufacturer-recommended brake fluid type (DOT 3 or DOT 4).
Inspect for any leaks in the brake lines or connections.

6. Reassemble and Test

Reconnect any components that were disconnected during the inspection.
Start the vehicle and observe if the ABS light remains on.
Conduct a test drive to ensure the ABS system is functioning correctly.
