Solution

1. Preparation

Gather tools and parts. Ensure the vehicle is parked on a level surface, and the ignition is off.
Tools required: OBD-II scanner, multimeter, socket set, torque wrench, brake cleaner.

2. Address Fault Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Retrieve and note any ABS fault codes.
Clear the fault codes and see if they return after a test drive.

3. Inspect and Clean Wheel Speed Sensors

Locate the ABS wheel speed sensors at each wheel hub.
Remove any dirt or debris around the sensors using brake cleaner.
Check the wiring harness for any signs of wear or damage.
If a sensor is faulty, remove it using a socket set, replace it, and torque to manufacturer specifications.

4. Check ABS Module and Wiring

Inspect the ABS control module for any corrosion or loose connections.
Use a multimeter to test the wiring for continuity and proper voltage.
If any wiring is damaged, repair or replace as necessary.

5. Brake Fluid Inspection

Check the brake fluid level in the master cylinder reservoir.
If the fluid is low, top up with the recommended fluid type (DOT 3 or DOT 4).
Inspect for any leaks in brake lines or around the master cylinder, repairing as needed.
