Solution

1. Preparation

Gather tools and materials needed for the repair.
Ensure the vehicle is on a level surface and securely lifted if necessary.
Disconnect the battery to prevent any electrical issues.

2. Inspect and Replace ABS Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Remove the cover and locate the ABS fuse. Use the diagram on the fuse box cover for reference.
Check the fuse for continuity using a multimeter; replace it if it is blown.

3. Check ABS Wheel Speed Sensors

Remove the wheel associated with the ABS sensor being tested.
Locate the ABS sensor on the wheel hub and disconnect the wiring harness.
Inspect the sensor for dirt or damage. Clean or replace as necessary.
Reconnect the sensor and reinstall the wheel.

4. Inspect Wiring Harness

Trace the wiring from the ABS sensors to the ABS control module.
Look for frayed wires, loose connections, or corrosion.
Repair or replace damaged wiring as needed to ensure solid connections.

5. Test and Refill Brake Fluid

Open the brake fluid reservoir under the hood and check the fluid level.
If low, top up with the recommended brake fluid (DOT 3 or DOT 4, as per the owner's manual).
Check for any leaks in the brake system that may be causing fluid loss.

6. Reconnect Battery and Clear Error Codes

Reconnect the battery after completing repairs.
Use the OBD-II scanner to clear any error codes.
Start the vehicle and check if the ABS light remains off.
