Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the negative terminal of the battery to prevent electrical shorts.

2. Address Fault Codes

Use the OBD-II scanner to retrieve and document any fault codes.
Clear the codes and see if they return after a test drive.

3. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Remove any dirt or debris using a clean cloth.
If damaged, replace the wheel speed sensors with new ones.

4. Check Brake Fluid and System

Open the hood and locate the brake fluid reservoir.
Ensure the fluid is at the correct level; top off with the manufacturer-recommended brake fluid if necessary.
Inspect brake lines for leaks or damage and repair as needed.

5. Test Throttle Position Sensor

Utilize a multimeter to check the voltage output of the throttle position sensor.
If the readings are inconsistent or out of specification, replace the throttle position sensor.

6. Reconnect Battery and Test Drive

Reconnect the negative terminal of the battery.
Start the vehicle and take it for a test drive to ensure the VSC light does not reappear and the vehicle handles normally.
