How Does the VSC System Works?

The main function of VSC is to help prevent wheel slip and loss of traction by decreasing engine power and separately applying brake force to each of the four wheels.  The VSC system of Toyota takes into consideration many sensors like:

  • Yaw Rate sensor
  • Steering angle sensor
  • ABS
  • Traction control sensors

When the VSC system takes control it generates stability correction to immediately place the vehicle back into the “Stable operation”, thereby reducing the number of road accidents.

The VSC is just like the internal traction control system of the car. The VSC system jerks to life whenever you drive through slippery roads and lose traction, thereby helping you steer the car properly. Each wheel of the car has electronic sensors that communicate with the Powertrain Control Module (PCM) of the car.

When the driver encounters steering control problems, the VSC system automatically reduces engine speed, while giving braking power to the wheels. The wheel sensors will then pass on the information about the horizontal and vertical motion of the wheels. So, if you notice the check VSC system light coming on, it means you could be having problems with your sensors, or the steering rack.
