What causes VSA light to come on?
The Vehicle Stability Assist (VSA) system is a critical safety feature in many modern vehicles, designed to help maintain traction and stability during challenging driving conditions. When the VSA light illuminates on your dashboard, it’s a signal that something may be amiss with this system. In this article, we’ll explore the common causes of the VSA light coming on and what you should do about it.
Understanding the VSA System
The VSA system works by monitoring your vehicle’s speed, steering angle, and wheel rotation to detect any loss of traction or stability. If the system senses that your car is skidding or losing control, it automatically applies braking to individual wheels and adjusts engine power to help you regain control. The VSA light serves as an indicator for the system’s status.
Common Reasons the VSA Light Comes On
There are several reasons why the VSA light might illuminate on your dashboard. Here are the most common causes:
- System Activation: The VSA light may briefly come on when the system is actively working to stabilize your vehicle. This is normal and usually happens during sharp turns, slippery roads, or sudden braking.
- Faulty Wheel Speed Sensors: The VSA system relies on wheel speed sensors to monitor traction. If one or more of these sensors fail, the system may not function properly, triggering the VSA light.
- Steering Angle Sensor Issues: The steering angle sensor helps the VSA system determine the direction of your steering. A malfunctioning sensor can cause the light to come on.
- Brake System Problems: Since the VSA system works closely with your vehicle’s brakes, issues such as low brake fluid, worn brake pads, or a malfunctioning ABS (Anti-lock Braking System) can trigger the light.
- Electrical or Software Malfunctions: Like any electronic system, the VSA system can experience glitches or software errors, leading to the light being illuminated.
What to Do When the VSA Light Comes On
If the VSA light comes on, here’s what you should do:
- Check for Temporary Activation: If the light turns off after a few seconds, it’s likely that the system was temporarily activated and there’s no cause for concern.
- Inspect Your Tires: Uneven tire wear or incorrect tire pressure can affect the VSA system. Ensure all tires are properly inflated and in good condition.
- Check Brake Fluid Levels: Low brake fluid can impact the VSA system. Top off the fluid if necessary, but consult a professional if the issue persists.
- Visit a Professional Mechanic: If the light remains on or is accompanied by other warning lights, it’s best to have your vehicle inspected by a qualified mechanic. They can diagnose the issue using specialized tools and ensure your VSA system is functioning correctly.
Why You Shouldn’t Ignore the VSA Light
The VSA system is a vital safety feature that helps prevent accidents by maintaining control of your vehicle. Ignoring the VSA light could compromise your safety, especially in adverse driving conditions. Addressing the issue promptly ensures that your car remains safe and reliable on the road.
Conclusion
While the VSA light can be alarming, it’s often a sign of a manageable issue. By understanding the common causes and taking appropriate action, you can ensure your vehicle’s stability and safety systems are in top condition.

Frequently Asked Questions
Will low tire pressure cause VSA light to come on?
If the low tire pressure indicator comes on, or the multi-information display shows a ''CHECK TPMS SYSTEM'' message, the VSA system automatically turns on even when the VSA system is turned off by pressing the VSA OFF switch (see page ).
What does VSA and triangle light mean?
Vehicle Stability Assist system
If you see that warning light triangle with an exclamation mark appear there's a simple explanation. This icon stands for your Honda vehicle's Vehicle Stability Assist system and will illuminate your dashboard when an issue with the system is detected.
How to get the VSA light off?
Press and hold the VSA OFF button until you hear a beep to turn VSA on or off. The VSA OFF indicator appears when the system is off. Traction control stops functioning, which may make it easier when trying to free your vehicle if it is stuck in mud or snow.
Is it OK to drive with VSA light on?
VSA System Indicator Light
If the light returns, then arrange a service inspection to diagnose the fault. In the meantime, it's perfectly safe to drive your car, but the VSA system won't be there to protect you in difficult conditions, so it's a good idea to drive with extra care until the problem is fixed.
How much does it cost to fix a VSA system?
When you notice the system starts malfunctioning and showing significantly visible or sensible symptoms, you will have to dig deep into the core price and solutions. Repairing a VSA system malfunction will cost between $1,200 and $1,800.
What causes VSA to malfunction?
There's a myriad of reasons why your VSA light could be on, ranging from minor hiccups to more serious system failures. Some common triggers include wheel-speed sensor issues, low brake fluid, and problems with the steering angle sensor.
What should I do if the triangle with exclamation point comes on in my car?
This indicator lets you know that there's a Critical Warning Message that you need to read as soon as possible, but it doesn't actually indicate a specific problem. Really, the triangle with an exclamation point is a catch-all warning light, designed to alert you to issues that your other lights won't catch!
Does VSA affect steering?
Vehicle Stability Assist™5 with traction control is designed to help the driver retain steering control while cornering and during maneuvers that could cause a loss of traction and directional control. VSA works by controlling brake pressure or engine power—or a combination of the two—depending on the situation.
Can low tire pressure cause traction control light to come on?
Again, technically, yes—but it could make driving more dangerous. You should try checking your tire pressure and adding air if needed whenever you notice this light is illuminated—but, if it's lit up along with the ABS traction control light, it's best to get your vehicle checked out as soon as possible.
How much to fix electronic stability control?
Depending on the vehicle, a replacement steering angle sensor can cost about $250, including labor. On occasion, a software reset or update might fix a problem with your ESC. Labor rates can also vary by vehicle make and model, as well as your region.
