The journey from Carl Benz’s patented open-roofed three-wheeled contraption, which started it all, has been a long one for automobile technology.
Power, comforts, and luxuries that no one in the 19th century could ever dream of have been provided by the factories and assembly lines for the past two centuries.
A lot has been incorporated into our vehicles.
We have refined the original function of transportation, introducing concepts like the automatic transmission and the Hill Start assist, as well as building in fail-safes that serve to protect and help the driver.
One of the fail-safes is the VSA, a technology that is very useful when installed.
Check VSA System Means
If the check VSA system warning light comes on, you should take it to a car mechanic to have it checked out.
There could be a fault with your brake switch, wheel speed sensor, yaw rate sensor, or VSA control module.
What is VSA?
This should sound familiar to people who drive an Acura. There is an exclamation mark on the triangular light symbol on the dashboard.
That is the light from the VSA. The vehicle stability assistant is put into the car to help guide traction on the road.
The VSA helps in:
- When driving in dangerous conditions, it helps the car to stay on track.
- It helps the traction between the tires and the road. It can either limit the wheel slip rate or reduce the engine speed.
What Does It Mean When the Light Comes on?
There is a triangular symbol with an exclamation mark on the dashboard, which is where the VSA light is located.
This implies that you can turn the light on or off when the system is turned off.
It serves as a reminder to switch on the car’s in-built safety options since you wouldn’t want to have one of the car’s in-built safety options off.
There is another VSA light, a more important one. It indicates whether or not there is a problem with the VSA system.
The VSA system light is what it is called. It is important to keep track of the condition of one of the most important safety technologies in the car by paying attention to this.
When this particular light comes on, it shows that it’s time for you to make repairs.
What Causes VSA System Light to Go on?
The guidance and control of the car and its traction during dangerous situations are dealt with by the VSA system.
Problems related to these things would only come on if they are faulty or not in the best condition.
If you are handy enough, you can either do it yourself or take it to a mechanic. Some things might cause the VSA warning light to light up.
Faulty Brake Switch
The VSA system is connected to the car’s brakes. Is it possible? The first course of action when a car is on is stability.
The vehicle can maintain this by reducing the engine output and the speed of the car. The brake light switch is connected to the pedal system.
When the brake is pressed the brake lights switch on and send a signal to the control module that the brakes have been engaged.
The anti-lock brake, push-button start, and VSA are some of the most important car systems. When the brake switch malfunctions, the VSA will come on.
The cost of fixing a faulty brake switch is not that high and is the best outcome of a faulty system. You will pay around $150 for parts and labor.
Wheel Speed Sensor Fault
It’s been known for a long time that a VSA wouldn’t function well if it was driven with unleveled wheels. Why is it that this is happening?
The wheel speed sensor is taken out of balance on readings. The wheel speed sensors read the speed of the wheels and send them back to the car’s control module.
The whole system would be hard to read and function if there was a faulty sensor. The VSA wouldn’t know how to fix the problem if the sensor wasn’t able to pick out a problem.
If you have a wheel speed sensor failure, it will cost you around $200-$250.
Yaw Rate Sensor Failure
You can tell from this pattern that most VSA problems are caused by the fact that there are small sensors that the system cannot function without.
There is a yaw rate sensor. The yaw rate helps to determine if the vehicle is in danger of sliding. The light would come on if the system was fully online.
The yaw rate sensor is more expensive to fix. You can expect to pay $700 for labor.
VSA Control Module
The Antilock braking system, the EBS, and the Traction control system are included in the control module of the VSA.
It stands to reason that the VSA system wouldn’t function properly. The most likely to fail is the control module, but it will be expensive to replace when it does.
A dealership will ask a lot of money for labor and parts.
How to Diagnose This Issue?
If you like to take matters into your own hands, there is a simple way to identify what’s causing the warning on your dashboard.
You need to have a code reader in your car. Depending on the codes displayed, you can identify the part that needs to be replaced.
If you don’t know what the error code means, please check the Acura OBD-II Trouble Codes.
How to Reset Acura Light VSA?
If you turn off the car and turn it back on, you’ll be able to reset the Acura VSA light.
This isn’t guaranteed to work, but it can sometimes cause the warning to go away. There is a diagnostic tool that you can get to reset the system.
Is the VSA the Same As Traction Control?
No. The two parts of the car are different. The traction control regulates the spin of the tires when the vehicle is in motion.
How to Identify When VSA Is On or Off?
When you decide to accelerate, your engine’s output can tell you if the VSA is on. The exclamation mark on the triangular symbol is not on.
When the VSA system is turned on, this comes on. Premium protection from the uncertainty of dangerous roads is assured by your system’s failsafe.
It’s a good idea for it to be on so that you are protected 24/7.
Is It OK to Drive with VSA Light on?
One of the most important safety features of your car is the VSA.
It is important to ensure that the system works at all times, as driving with a fault in the system can become a hazard.
If you fix the problem, you may be able to drive the car, but you need to remember that the vehicle lacks one of the main safety systems.
What Is the Cost to Fix a VSA System?
Depending on what is causing the issue, the cost to fix the system will be between $150 and $1500.
The cost to fix a faulty brake switch is about $150, while a bad VSA module costs around $1500.
It is possible to save money by buying second-hand parts, but be aware that there are risks and a shorter warranty.
To make sure you don’t replace the wrong part, you must have the car inspected by a professional mechanic.
One of the most important safety mechanisms your Acura comes equipped with is the VSA system, so make sure it works as it should.
A fault in the system won’t cause the car to go into limp mode, but you should fix it immediately.
