In most cases, drivers don’t want their dashboard to light up with warning lights while they’re driving.
When you keep getting warning messages on the dashboard of your car, it can be very frustrating and cause you great concern.
A Check VSA System warning message is among the most common Acura warning messages.
This article is organized so that I can explain the significance of the alert, as well as the main causes and recommendations for its resolution. Let’s begin.
VSA System in Acura
It helps optimize stability in vehicles by using Vehicle Stability Assist (VSA).
Several components of your vehicle are continually monitored by the electronic system. These include the yaw rate, wheel speed, steering angle, and lateral acceleration.
You are also alerted through the Check VSA System message when the system detects instability and imminent loss of control.
In this respect, it is obvious that the VSA system is a very important component that should be maintained in optimal condition at all times.
By modulating the engine’s power and applying brakes to specific wheels as needed, this system assists drivers in maintaining control of their vehicles.
Acura’s “Check VSA System” Message: What Does It Mean?
An Acura’s “Check VSA System” message indicates that there may be a problem with its vehicle stability assistance system.
In extreme driving conditions, such as when driving on slippery roads, this system provides an extra level of stability and traction.
Your vehicle will not slide or lose control if it is equipped with this feature.
There are a number of reasons why the Check VSA System alert appears on Acura vehicles, including faulty wheel speed sensors, malfunctioning yaw rate sensors, and improper alignment of the wheels.
Find out why and how you can resolve this warning light message by reading on.
Why does Acura’s “Check VSA System” alert appear?
Check VSA System messages on Acura dashboards are caused by the following factors:
1. Yaw sensor failure
In order for the VSA system to function properly, the yaw sensor is essential. Using this device, you can determine how much your car rotates around its vertical axis.
You will not be able to accurately calculate the VSA system’s accuracy if you have a defective yaw sensor.
Furthermore note that failing yaw sensors can cause various parts of the VSA system to undergo wear and damage, as well as causing electrical problems.
In the future, you may wish to check the yaw sensor in your Acura before checking the Check VSA System.
2. Sensor failure on the wheel speed
As well as the wheel speed sensor, the wheel angle sensor plays an important role in the VSA system.
Vehicle wheels are tracked with this sensor. It measures their rotational speed.
A wheel’s traction loss is determined by the information collected by the VSA system.
Wheel speed sensors that fail transmit data inaccurately or stop transmitting data at all. It is therefore possible to take appropriate action after seeing the warning message.
3. Problems with ABS modules
There are also warning messages that can be triggered by ABS module issues.
Besides being closely coupled to the VSA system, the ABS module controls the performance of the entire ABS system.
You might have to check VSA System in Acura if the ABS module is damaged.
4. Misalignment of the wheels
The warning message can also be caused by this issue, which isn’t always obvious.
The steering response of your vehicle and its stability are significantly affected by improperly aligned wheels.
As a result of its reliance on accurate wheel location information, the VSA system must function correctly.
If you’ve recently had impacts or driven on roads with many potholes or off-road, you should have your Acura’s wheel alignment checked.
5. Sensor for steering angle
The sensor may be giving your VSA system problems. I should have mentioned it earlier.
As your car follows your directions, the steering angle sensor detects deviations.
Especially when navigating tight bends or driving on slippery roads, a faulty steering angle sensor can cause an accident.
A computer glitch or physical damage may have caused the steering angle sensor to be damaged.
After ruling out the above possible causes, check this sensor if you see the Check VSA System message.
6. Modulator for VSA is faulty
When the VSA system is activated, this modulator controls the brake pressure. VSA’s performance is largely influenced by this component.
Therefore, a warning message will be displayed if the VSA system is damaged. In order to eliminate any possible issues with the modulator, make sure to check it.
7. Mismatched Tires
It is also possible that the Check VSA System alert can be caused by mismatched tires on your Acura.
The VSA system functions best when there is consistent traction at all wheels.
To avoid wearing out your wheels, use wheels with similar tread patterns, sizes, and wear levels.
Acura Check VSA System Fix and Reset
Acura Check VSA System can be fixed in a number of ways. The following are just a few:
Certified technicians should inspect your vehicle:
The Check VSA System in Acura can be caused by a variety of serious issues.
You should not attempt to repair any problems on your own unless you are a certified technician.
Additionally, you can visit an Acura Service Center if you have an Acura vehicle.
Your car should be aligned and calibrated as needed:
The alignment and calibration of the wheels is another possible fix. Ensure that all the wheels are aligned correctly by having a technician adjust the angles.
Replacement of VSA modulator:
Replace the VSA modulator immediately if you have determined it’s the cause of the warning message.
If the yaw sensor is defective, it may need to be replaced, as may the steering angle sensor, the wheel speed sensor, and the wheel speed sensor.

Frequently Asked Questions
What is the VSA System?
The Vehicle Stability Assist (VSA) system, also known as Electronic Stability Control (ESC), is designed to enhance vehicle stability during cornering and maintain traction on slippery surfaces. It achieves this by regulating engine output and selectively applying brakes to individual wheels when necessary.
How does the VSA System work?
The VSA system monitors various sensors to detect conditions like understeer or oversteer. When it activates, you may notice a reduction in engine power and some noise from the hydraulic brake system. The VSA indicator light will blink during operation, indicating that the system is actively helping to stabilize the vehicle.
What should I do if the VSA indicator light stays on?
If the VSA system indicator light remains illuminated while driving, it may indicate a problem with the system. In this case, it is advisable to pull over safely, turn off the engine, and restart it. If the light returns, you should have your vehicle checked by an Acura dealer as soon as possible.
Can I disable the VSA System?
Yes, you can partially disable the VSA functionality by pressing and holding the VSA OFF button until you hear a beep. However, this will reduce traction control effectiveness. It is recommended to turn VSA back on after situations like getting stuck in mud or snow.
Is it safe to drive if the VSA System is not functioning?
While you can drive without the VSA system, it is important to exercise extra caution as the vehicle will lack enhanced stability and traction control features. Always drive at speeds appropriate for road conditions and maintain a safe distance from other vehicles.
Where can I find more information about my Acura’s VSA System?
For detailed information about your specific model’s VSA system, refer to your owner’s manual or visit Acura’s official website where you can download relevant documents regarding vehicle stability assist functionalities.
