If you're the proud owner of either a Toyota or Lexus, you might've come across the acronym, VSC. It otherwise stands for Vehicle Stability Control, which is Toyota's way of naming its electronic stability program. Compared to more conventional traction control software, electronic stability control systems like VSC are much more advanced and capable. VSC is handily able to take control of your car's brakes and engine to ensure that your car is more stable. For example, if you're losing control of your car on a snowy road, VSC will reduce the engine power and gradually up the braking force to keep you steady.
