Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface, and engage the parking brake.
Disconnect the vehicle's battery to ensure safety while inspecting electrical components.

2. Scan for Fault Codes

Use an OBD-II scanner to read any diagnostic trouble codes (DTCs).
Document any codes related to the VSC system and proceed with targeted repairs based on the codes.

3. Inspect and Replace Faulty Components

A. Wheel Speed Sensors

Tools Required: Socket set, torque wrench
Sub-steps:
1. Remove the wheel to access the wheel speed sensor.
2. Unplug the sensor connector and remove the mounting bolts.
3. Install the new sensor and torque the bolts to manufacturer specifications.
4. Reconnect the sensor and wheel.

B. Brake Fluid

Tools Required: Brake fluid, funnel, clean cloth
Sub-steps:
1. Check the brake fluid reservoir for proper level and condition.
2. If low, add the appropriate brake fluid (DOT 3 or DOT 4 as specified).
3. Clean any spills.

C. Brake Pedal Switch

Tools Required: Multimeter
Sub-steps:
1. Locate the brake pedal switch and disconnect the wiring harness.
2. Use a multimeter to test continuity; replace the switch if it fails the test.
3. Reconnect the wiring harness.

4. Clear Fault Codes

After repairs are made, use the OBD-II scanner to clear any stored fault codes.
Reconnect the battery if it was disconnected earlier.

5. Test Drive

Take the vehicle for a test drive to ensure the VSC system is functioning correctly and that the warning light does not reappear.
