Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, brake cleaner.
Safety Warnings: Disconnect the battery before working on electrical systems to prevent shorts.

2. Address Error Codes

Use the OBD-II scanner to retrieve and note any ABS-related trouble codes.
Research the specific codes to determine the faulty component.

3. Inspect Fuses and Relays

Locate the fuse box (usually under the dashboard or hood).
Remove the ABS fuses and check them for continuity using a multimeter.
Replace any blown fuses and ensure all relays are functioning properly.

4. Check Brake Fluid and System

Check the brake fluid reservoir; refill if low with the manufacturer-recommended brake fluid.
Inspect the brake lines for leaks, paying special attention to connections and fittings.

5. Inspect Wheel Speed Sensors

Lift the vehicle using a jack and secure it with jack stands.
Locate each wheel speed sensor on the brake assembly.
Clean any dirt or debris from the sensor area and verify the wiring integrity.
Use a multimeter to check the sensor’s resistance; replace any faulty sensors.

6. Inspect ABS Control Module

Visually check the ABS control module for signs of physical damage or corrosion.
If necessary, remove the module and clean the contacts with electrical cleaner.
Reinstall the module ensuring all connections are secure.

7. Reconnect Battery and Test

Reconnect the battery and start the vehicle.
Clear any stored codes using the OBD-II scanner.
Take the vehicle for a test drive to check if the ABS light remains off and the braking system operates correctly.
