Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and brake fluid.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Retrieve Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition key to the "ON" position without starting the engine.
Follow the scanner instructions to retrieve and note any error codes related to the VSC system.

3. Inspect Wheel Speed Sensors

Raise the vehicle and securely support it on jack stands.
Remove the wheel to access the wheel speed sensors.
Visually inspect each sensor for damage, dirt, or corrosion, and check the wiring connections.
Use a multimeter to test sensor resistance; compare results with manufacturer specifications.

4. Check Brake Fluid Level

Locate the brake fluid reservoir and check the fluid level.
If low, top off with the recommended brake fluid type (usually DOT 3 or DOT 4).
Inspect for any leaks in the brake lines or around the master cylinder.

5. Test VSC Control Module

Reconnect the battery terminal.
With the OBD-II scanner still connected, clear any error codes and perform a test drive.
Monitor the system for any reoccurrence of the VSC warning light.
If the warning persists, it may indicate a faulty VSC control module, requiring replacement.
