Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to prevent any electrical shorts.

2. Inspect and Replace ABS Fuse

Locate the fuse box under the dashboard or hood.
Remove the ABS fuse and check it for continuity using a multimeter.
If the fuse is blown, replace it with a new one of the same amperage.

3. Check and Replace Wheel Speed Sensors

Lift the vehicle using a jack and secure it with jack stands.
Locate the wheel speed sensors on each wheel hub.
Disconnect the sensor wiring harness and remove the sensor using a socket set.
Inspect the sensor for dirt or damage and replace if necessary.

4. Inspect ABS Module Wiring

Visually inspect the wiring harness connected to the ABS module for any frays or corrosion.
If damaged, repair or replace the wiring as needed.
Reconnect all electrical connectors ensuring they are secure.

5. Refill Brake Fluid

Check the brake fluid level in the master cylinder reservoir.
If low, add the appropriate type of brake fluid (consult the owner's manual for specifications).
Bleed the brakes if necessary to remove any air trapped in the system.

6. Reconnect Battery and Test

Reconnect the battery terminals securely.
Start the vehicle and check if the ABS light remains illuminated.
Perform a test drive to ensure ABS is functioning properly.
