Solution

1. Preparation

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

2. Inspect and Clean Wheel Speed Sensors

Remove the wheel where the ABS light is indicated.
Locate the wheel speed sensor and disconnect the electrical connector.
Clean the sensor and the area around it with brake cleaner.
Reconnect the sensor and ensure it is securely mounted.

3. Check Brake Fluid and Lines

Open the hood and locate the brake fluid reservoir.
Inspect the fluid level, and top it off with the manufacturer-recommended brake fluid if low.
Visually inspect brake lines for leaks or damage; replace any damaged lines.

4. Test ABS Module and Pump

Reconnect the battery and use the OBD-II scanner to clear any existing error codes.
Test the ABS pump operation by activating it through the scanner or manually; ensure it engages and disengages correctly.
If the pump does not operate, consider replacing the ABS module.

5. Reassemble and Test

Reinstall any components removed during inspection.
Reinstall the wheel and securely tighten lug nuts to manufacturer specifications.
Perform a test drive to ensure the ABS light does not re-illuminate and that the brakes function properly.
