Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is turned off.
Disconnect the battery to avoid electrical short circuits.

2. Inspect and Clean ABS Sensors

Remove the wheel corresponding to the ABS light.
Locate the ABS sensor mounted on the wheel hub.
Clean the sensor and its mounting area with brake cleaner to remove dirt and debris.
Reinstall the wheel and lower the vehicle.

3. Check and Repair Wiring

Inspect the wiring harness connected to the ABS module for any frays or disconnections.
Use a multimeter to check for continuity in the wiring.
Repair or replace damaged wiring as necessary.

4. Replace Faulty ABS Sensor (if necessary)

If the ABS sensor is found to be faulty during inspection, remove it from the wheel hub.
Install the new ABS sensor, ensuring it is properly aligned.
Reconnect any electrical connectors and secure the wiring.

5. Refill Brake Fluid (if necessary)

Open the master cylinder reservoir cap.
Check the brake fluid level; if low, top off with the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
Reinstall the cap securely.

6. Reconnect Battery and Test

Reconnect the battery terminals.
Start the vehicle and check if the ABS warning light is still illuminated.
Perform a test drive to ensure the ABS functions correctly.
