Solution

1. Preparation

Gather tools and parts required.
Disconnect the battery negative terminal to ensure safety while working on electrical components.

2. Inspect and Clean Wheel Speed Sensors

Tools Required: Socket set, cleaning brush, brake cleaner.
Remove the wheel corresponding to the sensor showing issues.
Locate the wheel speed sensor and disconnect the electrical connector.
Remove the sensor from its mount and clean it with brake cleaner to remove any debris.
Reinstall the sensor and reconnect the electrical connector.

3. Check Brake Fluid Level

Inspect the brake fluid reservoir under the hood.
If the fluid is low, top it up with the manufacturer-recommended brake fluid type (typically DOT 3 or DOT 4).
Reconnect the battery terminal.

4. Reset VSC System

Tools Required: OBD-II scanner.
Use the OBD-II scanner to clear any stored trouble codes related to the VSC system.
Start the vehicle and check if the VSC light remains illuminated.

5. Replace Faulty Components (if necessary)
