Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to ensure safety while working on electrical components.

2. Address Error Codes

Connect the OBD-II scanner and record any diagnostic trouble codes (DTCs).
Clear the codes and take the vehicle for a test drive to check if the stability control light reappears.

3. Wheel Speed Sensor Inspection

Remove the wheel of the affected axle to access the wheel speed sensors.
Inspect the wiring harness for frays or disconnections.
Clean the sensor area and connector with electrical contact cleaner.
Reinstall the wheel and torque it to the manufacturer's specifications.

4. Brake System Inspection

Check the brake fluid level in the master cylinder reservoir.
If low, inspect for leaks in brake lines or calipers.
Top off with the manufacturer-recommended brake fluid if necessary.

5. Steering Angle Sensor Calibration

If DTCs indicate a steering angle sensor issue, follow the manufacturer’s procedure for recalibration using a diagnostic tool.
Ensure that the steering wheel is centered before recalibration.

6. Final Checks and Reassembly

Reconnect the battery and turn on the ignition.
Check for any remaining error codes.
Test drive the vehicle to ensure stability control light is off and systems are functioning correctly.
