Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and set the parking brake.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect ABS Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Clean any dirt or debris from the sensor area.
Visually inspect the wiring and connectors for damage.
If damaged, replace the sensor with a new one.

3. Check and Replace Brake Fluid

Inspect the brake fluid reservoir for low fluid levels.
If low, top off with the recommended brake fluid (DOT 3 or DOT 4, depending on your vehicle).
If the fluid is dark or contaminated, perform a brake fluid flush and replace with new fluid.

4. Replace ABS Fuse

Locate the fuse box and identify the ABS fuse.
Remove the fuse and inspect it; replace it with a new fuse of the same amperage if it is blown.

5. Test and Reconnect Battery

Reconnect the negative battery terminal.
Start the vehicle and observe if the ABS warning light has turned off.
If the light remains on, further diagnostics may be necessary.
