Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is turned off.
Disconnect the battery to prevent any electrical shorts.

2. Scan and Clear Fault Codes

Use the OBD-II scanner to check for stored fault codes.
Clear any codes present and retest the system to see if the light returns.

3. Inspect Wheel Speed Sensors

Remove the wheel on the affected side to access the wheel speed sensor.
Clean the sensor and its connector.
Reconnect the sensor and ensure it is properly secured.

4. Check Brake System

Inspect brake fluid level in the reservoir. Top off with the manufacturer's specified brake fluid if necessary.
Examine brake pads for wear, replacing them if they are below the manufacturer's thickness specifications.

5. Steering Angle Sensor Calibration

Follow the vehicle's service manual for the specific calibration procedure of the steering angle sensor.
Use a diagnostic tool to perform the calibration if necessary.

6. Reassemble and Test Drive

Reinstall the wheel and lower the vehicle to the ground.
Reconnect the battery.
Conduct a test drive to verify that the stability control light no longer illuminates and that the system functions correctly.
