Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check and Replace ABS Fuse

Locate the fuse box, typically under the dashboard or in the engine compartment.
Use a fuse puller to remove the ABS fuse and inspect it for continuity.
If the fuse is blown, replace it with a new fuse of the same amperage rating.

3. Inspect and Clean Wheel Speed Sensors

Raise the vehicle using a jack and secure it with jack stands.
Locate the wheel speed sensors on each wheel hub.
Disconnect the sensor connector and remove any dirt or debris around the sensor.
Clean the sensor with a soft cloth and reconnect it securely.

4. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Inspect the fluid level; if low, top it off with the manufacturer-recommended brake fluid.
If the fluid is contaminated, consider flushing the brake system.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and check if the ABS light remains on.
Perform a test drive to confirm that the ABS system is functioning correctly.
