Solution

1. Preparation

Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical shorts.
Gather necessary tools and parts.

2. Retrieve and Interpret Diagnostic Codes

Using the OBD-II scanner, connect it to the vehicle's diagnostic port.
Record any trouble codes that appear, particularly those related to the VSC or ABS systems.
Clear the codes and conduct a test drive to see if the warning reappears.

3. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove any dirt or debris from the sensor and mounting area using a soft cloth.
Check the wiring for any signs of wear or disconnection; repair or replace as necessary.

4. Check Brake Fluid and System

Inspect the brake fluid reservoir for proper fluid level—top off with manufacturer-recommended brake fluid if low.
Look for leaks in brake lines and components; replace any damaged parts.
If the fluid is contaminated, flush the brake system.

5. Test and Calibrate Steering Angle Sensor

Using a diagnostic tool, navigate to the steering angle sensor settings.
Follow the tool’s prompts to calibrate the sensor as per manufacturer specifications.
Clear any codes and retest the VSC system.
