Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Scan and Clear Codes

Use the OBD-II scanner to read and document any DTCs.
Clear the codes and test drive the vehicle to see if the stability control light returns. If it does, note the new codes for further diagnosis.

3. Inspect and Replace Wheel Speed Sensors

Locate each wheel speed sensor near the brake rotor.
Disconnect the sensor wiring harness and remove the sensor using a socket wrench.
Inspect the sensor for wear or damage; replace if necessary.
Reinstall the new sensor, ensuring proper torque specifications (typically around 7-10 ft-lbs).
Reconnect the wiring harness.

4. Test Steering Angle Sensor

If necessary, recalibrate the steering angle sensor using a scan tool.
Follow the manufacturer's procedure for calibration to ensure proper function.

5. Reconnect Battery and Test

Reconnect the battery and ensure all connections are tight and secure.
Perform a test drive to check for the stability control light and verify system function.
