The VSA system keeps your car stable and maintains traction when accelerating, braking, or turning suddenly.
This technology instantly identifies any instability or loss of traction and then applies the brakes to specific wheels to keep the vehicle stable. It keeps track of wheel speed, steering angle, and lateral acceleration using sensors placed throughout your car.
Now the question is what does it mean when your acura vsa warning light become on. Is it safe to drive with VSA light on. Let’s have a look on this article to resolve your query.
VSA system prevents the car from sliding while making sharp turns.
What does the Acura VSA Light On Mean?
If the VSA light on your dashboard is on, the stability control system is not operating properly. Because of this, your car may be more likely to slide or crash during sharp bends or stops.
Now, is it safe to drive with vsa light on? No, you and your passengers may be in danger if you drive with the VSA light on, and it could also seriously damage your car.
Why Acura Check VSA System Light Become On – 7 Reasons To Check
The VSA light in your car could turn on for a variety of reasons. This is a list of the most typical causes:
1. Insufficient Brake Fluid
The hydraulic pressure created by the brake fluid is what drives the VSA system. There might not be enough pressure to operate the VSA system when the brake fluid level is low, turning on the warning light.
According to a report by Honda Motor Company, when the brake fluid level falls below a specified limit, the sensor sends a signal to the electronic control unit (ECU).
The ECU then turns on the VSA warning light on the dashboard to notify the driver of the low brake fluid level.
2. An Unreliable Steering Angle Sensor
In an Acura, the steering angle sensor detects the steering wheel’s angle and sends that information to the VSA control module. This determines the direction and amount of wheel rotation.
If the sensor is faulty, it can send incorrect signals to the VSA control module, which can affect the vehicle’s stability and trigger the warning light.

3. Faulty VSA Modulator Control Unit
The VSA modulator control unit controls the hydraulic pressure in the braking system, which is essential for the efficient operation of the VSA system.
If the control unit malfunctions, it can cause a loss of hydraulic pressure or incorrect pressure regulation, which can affect the VSA system’s performance.
4. Low Battery Voltage
Low battery voltage can damage the VSA system’s capacity to receive and interpret information from the wheel speed sensors and control the brake pressure. This can result in the VSA light turning on in an Acura.
5. Wheel Speed Sensor Issues
The VSA system uses wheel speed sensors to assess each wheel’s speed and compare it to the other wheels to determine the direction and stability of the vehicle.
The VSA control module may interpret the data incorrectly and activate the warning light if one sensor gives the wrong signals.
6. Uniform Wheel Size
According to a study, if the wheel sizes on your car are not uniform, the rotational speed of each wheel can vary, which can trigger the VSA system. This can cause the VSA light to turn on.
7. Worn Brake Pads
The functionality of the ABS and VSA systems can be impacted by worn braking pads. When the brakes are applied, the ABS and VSA systems work together to maintain control and stability by modulating the brake pressure to each wheel. As a result, the VSA light may turn on to indicate a problem.
