Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secured with wheel chocks.
Wear safety gloves and goggles.

2. Scan for Codes

Use an OBD-II scanner to retrieve any ABS-related trouble codes.
Document the codes for further analysis.

3. Inspect Wheel Speed Sensors

Locate the wheel speed sensors at each wheel.
Disconnect the sensor wiring harness and inspect for corrosion or damage.
Clean the sensors with electrical contact cleaner and reattach.
If damaged, replace the sensors with new ones.

4. Check ABS Module

Access the ABS module, typically located near the brake master cylinder.
Inspect wiring harnesses for loose connections or frayed wires.
If codes indicate a faulty module, replace it with a compatible unit.

5. Inspect Brake Fluid and Leaks

Open the brake fluid reservoir and check fluid level. Refill if low with the manufacturer's recommended brake fluid.
Inspect brake lines and connections for leaks; repair or replace as necessary.

6. Test Drive and Clear Codes

After repairs, perform a test drive to ensure ABS functionality.
Re-scan with the OBD-II scanner to clear any stored ABS codes and verify that the ABS light is off.
