Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in a safe, flat area and secure it with wheel chocks.
Disconnect the vehicle's battery (negative terminal) for safety.

2. Inspect the ABS Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Remove the ABS fuse and inspect it for continuity using a multimeter.
If the fuse is blown, replace it with a new one of the same amperage.

3. Check Wheel Speed Sensors

Raise the vehicle and securely support it on jack stands.
Locate the wheel speed sensors on each wheel.
Disconnect the electrical connectors and inspect for corrosion or damage.
Clean or replace damaged sensors as needed.

4. Inspect Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Check the fluid level; it should be between the "MIN" and "MAX" marks.
If low, top off with the manufacturer-recommended brake fluid (DOT 3 or DOT 4).

5. Test ABS Control Module

Reconnect the battery after completing previous steps.
Use an OBD-II scanner to clear any existing codes.
Perform a test drive to check if the ABS light remains off.
If the light returns, the ABS control module may need replacement.
