Solution

1. Preparation

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

2. Address Faulty Wheel Speed Sensors

Locate the wheel speed sensors at each wheel.
Remove any dirt or debris around the sensor area to prevent contamination.
Disconnect the electrical connector from the sensor.
Remove the sensor using a socket set (usually 10mm socket).
Inspect the sensor for damage; replace if necessary.
Reinstall the new or cleaned sensor and reconnect the electrical connector.

3. Check and Replace ABS Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Use a fuse puller to remove the ABS fuse.
Inspect the fuse for continuity; replace with a new fuse of the same amperage (refer to your owner's manual for specifications).
Reinstall the fuse and ensure it is seated properly.

4. Inspect and Repair Wiring

Visually inspect the wiring harnesses connected to the ABS module for any signs of wear or damage.
Use a multimeter to test for continuity in the wiring. Repair or replace any damaged wires.
Ensure all connections are secure and free of corrosion.

5. Reconnect Battery and Clear Codes

Reconnect the battery terminals.
Use the OBD-II scanner to clear any ABS fault codes.
Start the vehicle and check if the ABS light is still illuminated.
