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 prevent electrical shorts.

2. Retrieve and Clear Codes

Reconnect the OBD-II scanner and retrieve any fault codes.
Clear the codes and see if the ABS light returns after a test drive.

3. Inspect ABS Sensors

Raise the vehicle and remove each wheel.
Inspect each ABS sensor for physical damage or dirt buildup.
Clean any dirt or debris from the sensor area and check the mounting points for security.

4. Check Wiring and Connections

Visually inspect the wiring harness connected to the ABS sensors for any frays or breaks.
Reconnect any loose connections securely.

5. Test ABS Control Module

Using a multimeter, check for power and ground at the ABS control module.
If there are no readings, check the fuses related to the ABS system.

6. Brake Fluid Inspection

Check the brake fluid reservoir for proper fluid level and condition (should be clear, not dark or contaminated).
If low, top off with the recommended brake fluid type as specified in the owner's manual.

7. Reassemble and Test

Reinstall the wheels and lower the vehicle.
Reconnect the negative battery terminal and perform a test drive to check if the ABS light remains off.
