Solution

1. Preparation

Gather necessary tools and parts. Ensure the vehicle is parked on a level surface and the engine is off.
Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, brake fluid.

2. Address Fault Codes

Use the OBD-II scanner to read and note any fault codes.
Clear the codes and perform a test drive to see if they return. If they do, proceed with further inspection based on the codes received.

3. Inspect and Replace Components

Brake Fluid Inspection:
- Open the hood and locate the brake fluid reservoir. Check the fluid level and condition.
- If the fluid is low, refill it with the manufacturer-recommended brake fluid.
Wheel Speed Sensors:
- Raise the vehicle using jack stands and remove the wheel to access the wheel speed sensors.
- Inspect each sensor for dirt buildup or physical damage. Clean or replace as necessary.
Brake Light Switch:
- Locate the brake light switch near the brake pedal. Test its function with a multimeter.
- If faulty, replace the brake light switch.

4. Final Checks

Recheck all connections and ensure no wires are frayed or disconnected.
Reinstall wheels (if removed) and lower the vehicle.
Test drive the car to verify that the "Check VSC System" warning has cleared.
