Solution

1. Preparation

Gather tools and parts: Ensure all necessary tools and replacement parts are readily available.
Safety check: Disconnect the vehicle battery before working on the ABS system.

2. Inspect Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove any dirt or debris around the sensors using a clean cloth.
Check the wiring harness for damage or disconnections.
If damaged, replace the faulty wheel speed sensor.

3. Check ABS Fuse

Open the fuse box located under the dashboard or hood.
Locate the ABS fuse and visually inspect it for continuity.
If the fuse is blown, replace it with a new one of the same amperage.

4. Examine the ABS Control Module

Remove any covers or panels obstructing access to the ABS control module.
Inspect the module for signs of moisture, corrosion, or physical damage.
If the module is faulty, replace it with a compatible unit.

5. Refill Brake Fluid

Check the brake fluid level in the master cylinder reservoir.
If low, add the recommended brake fluid (DOT 3 or DOT 4) to the proper level.
Bleed the brake system if necessary to eliminate air pockets.

6. Reconnect Battery and Test

Reconnect the vehicle battery.
Start the engine and check if the ABS light remains illuminated.
Perform a test drive to ensure the ABS system is functioning correctly.
