Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Inspect and Clean Wheel Speed Sensors

Locate the ABS wheel speed sensors on each wheel.
Remove any dirt or debris around the sensors using a soft brush or cloth.
Check the wiring harness for any signs of wear or damage.
Reconnect any loose connectors securely.

3. Replace Faulty ABS Fuse (if necessary)

Locate the fuse box and identify the ABS fuse using the owner's manual.
Remove the ABS fuse using a fuse puller.
Inspect the fuse; if blown, replace it with a new fuse of the same amperage rating.
Reinstall the fuse and close the fuse box.

4. Check and Refill Brake Fluid

Inspect the brake fluid reservoir for the fluid level.
If low, use the manufacturer-recommended brake fluid type to refill it to the proper level.
Ensure there are no leaks in the brake lines or reservoir.

5. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any ABS-related error codes.
Start the vehicle and check if the ABS light remains off.
