Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery terminal to prevent accidental electrical shorts.

2. Scan and Clear Codes

Use the OBD-II scanner to read any error codes related to the stability control system.
Document any codes found for reference.
Clear the error codes and recheck if the stability control light returns.

3. Inspect ABS Sensors

Locate the ABS sensors on each wheel hub.
Remove any dirt or debris around the sensors.
Check the wiring harness for any frays, corrosion, or loose connections.
If a sensor is found faulty, replace it with a new one, ensuring proper alignment and securing connections.

4. Brake System Check

Inspect brake fluid levels in the reservoir; refill with manufacturer-recommended fluid if low.
Check for any leaks in brake lines or around the master cylinder.
If brake pads are worn unevenly, replace them and ensure the brake system is properly bled to remove air.

5. Reassemble and Reconnect

Reconnect the negative battery terminal.
Ensure all components are securely fastened and that no tools are left in the engine bay.
