A common problem with Toyota and Lexus vehicles is that you might find the “VSC OFF” and “Check Engine” lights lit simultaneously. We’ll walk you through what this means and ideas to fix it.
Most Toyota owners will find that when the Check Engine and VSC lights are lit, there is a problem with an O2 Sensor or gas cap. Try tightening or replacing the gas cap for a hopefully cheap fix.
VSC System OFF and Check Engine Light is On
If you notice that the “VSC Off” icon is on, don’t worry because your car is still safe to drive. But, you must be careful on the snow or slippery road because the car won’t stabilize itself. VSC stands for “Vehicle Stability Control.” It is likely that “Traction Control” will not work while this light is illuminated. On some vehicles, the “skidding vehicle” or “TRAC OFF” light may also be lit as well.
How to Fix the Problem
To fix the ‘VSC Off,’ you might have to read codes for diagnostic information. An OBD2 Scanner can help you pinpoint the exact cause of the problem, whether it’s an ABS or engine sensor. When the VSC Off light turns on, the check engine light goes on too. To reset both without a scanning tool, disconnect and re-connect the terminals after 10 minutes.
To be sure of the problem, you may want to take your vehicle to an Auto Zone or NAPA store to have them plug in a code reader to determine the problem. Another option would be to take the vehicle in for service.
If your problem turns out to be O2 sensor related, you can continue driving the vehicle without problems, but you may not achieve the most efficient gas mileage. O2 sensors can be difficult or easy to replace depending on the make and model of the vehicle. Some require access under the vehicle, while others are accessible under the hood.
VSC System ON
When the VSC System is ON, it automatically redirects engine power from certain wheels, playing an active role in stabilizing your car from losing traction. In Toyota and Lexus models, traction control ensures that a vehicle does not skid in hostile weather by correcting its course.
Models with a VSC system include:
- Toyota Camry
- Toyota Avensis
- Toyota Verso
- Toyota Sienna
- Lexus RX400H
- Lexus is250
- Lexus is220d
