Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Retrieve and Analyze Error Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Retrieve any stored codes related to the VSC system and note them for reference.

3. Inspect and Replace Faulty Components

Brake Fluid Check:
- Remove the brake fluid reservoir cap.
- Check the fluid level and condition; if dirty or low, top off with the recommended brake fluid (DOT 3 or DOT 4).
ABS Sensor Inspection:
- Lift the vehicle and remove the wheel to access the ABS sensor.
- Disconnect the sensor connector and visually inspect for any damage or dirt.
- If damaged, replace the ABS sensor.
Brake Pedal Switch Check:
- Locate the brake pedal switch under the dashboard.
- Use a multimeter to test if the switch is closing when the brake pedal is pressed.
- If faulty, replace the brake pedal switch.

4. Repair or Replace Wiring and Control Module

Inspect the wiring harness connected to the VSC control module for wear or damage.
Repair any frayed wires and ensure all connectors are clean and securely connected.
If the control module is determined to be faulty based on diagnostic codes, replace it following manufacturer guidelines.

5. Clear Codes and Test Drive

Once repairs are completed, use the OBD-II scanner to clear any diagnostic trouble codes.
Start the vehicle and conduct a test drive to ensure the VSC system is functioning properly.
