VSC light is the Vehicle Stability Control light. VSC, which stands for Vehicle Stability Control, is a system utilized by Toyota and Lexus to manage traction control. When the VSC light illuminates on the vehicle’s dashboard, it indicates a problem with the traction control system, resulting in the temporary disabling of the VSC and ABS (Anti-lock Braking System) systems. The SC system enhances the vehicle’s grip on the road by reducing engine power to the wheels and applying brake force through the ABS system when necessary. This helps prevent wheel slippage and loss of traction, particularly in challenging driving conditions. If the dashboard displays a “VSC OFF” warning light, it signifies that the traction control is completely deactivated. In such instances, the traction control system will not intervene or assist if the vehicle experiences a loss of grip or traction. It is worth noting that newer Toyota or Lexus models may show a “Check VSC system Light” message instead of the standard VSC light.
