Solution

1. Preparation

Gather tools and equipment (OBD-II scanner, multimeter, socket set).
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical shorts.

2. Inspect ABS Wheel Speed Sensors

Remove the wheel to access the ABS sensor.
Disconnect the sensor's electrical connector.
Use a multimeter to measure the resistance of the sensor; it should typically be between 1.0 to 1.5 kΩ.
Clean any debris from the sensor and its mounting area.
Reconnect the sensor and wheel, ensuring the connection is secure.

3. Check ABS Control Module and Wiring

Locate the ABS control module and visually inspect for any physical damage or corrosion.
Use a multimeter to check the power and ground circuits at the ABS module connector.
Repair or replace damaged wiring as necessary.

4. Replace ABS Fuse (if blown)

Locate the fuse box and identify the ABS fuse.
Remove the fuse and inspect it for continuity; if blown, replace with a fuse of the same amperage.
Reinstall the fuse and ensure it is seated properly.

5. Reset ABS Light

Reconnect the battery.
Use an OBD-II scanner to clear any stored ABS codes.
Start the vehicle and check if the ABS light remains off.
