How Does the VSC System Work?
The Vehicle Stability Control (VSC) is governed by a computer system which uses sensors to gather information about the vehicle being driven. It compares this information with driver actions and road results and decides what the best course of action is. The VSC system control is located on the anti-lock braking system and it includes an anti-skid system.
The main purpose of the VSC driver assistance system is to help the vehicle go at a suitable speed and to curtail oversteer and understeer. It helps reduce the chances of skidding or moving sideways by applying braking torque on the opposite lock which prevents the skid or limits the skid. The driver assistance system combined with the ABS system control the braking to ensure that the driver has a safer ride.
You can also reset the VSC System without travelling to the service station and having special car tools. While there is no reset button on the VSC system, you can easily reset the system using the power steering.
Steps to Reset the VSC System:
Step 1. Start the engine
Step 2. Turn the ignition key to the ACC position (this turns off the engine)
Step 3. Wait at least five seconds
Step 4. Turn the ignition key to the OFF position again
Step 5. Turn the ignition key back to the ACC position (this turns on the engine)
Step 6. Start the engine and drive normally
What Causes the VSC System Light to Go On?
There are a wide variety of reasons why the VSC system may not be functioning correctly. Some of the most common issues include:
- Loose wheel lug nuts
- Excess wear on a tire’s tread
- Under-inflation or over-inflation of a tire
- Sliding around due to an unequal tire load distribution
- Sticking due to road conditions or other factors
- Problematic speed sensors
- Broken speedometer cables
- Faulty brake system due to corrosion, damage, or wear and tear
- Defective ignition switch
- Exhaust leak
In any of these situations, the system calculates the difference between the rotational speed of the wheels and the rotational speed of the tires. If the system finds an inconsistency between the two, it orchestrates the necessary measures to stabilize your vehicle’s speed and lets you know what is going on with visual indicators and audible alarms.
The most common of these include the appearance of the VSC light and the activation of the TC Lock feature.
When you drive on the highway or a clear road, the front wheels move smoothly and in harmony with the rear wheels. When one of them begins to rotate slower or faster than the other, the TC Lock feature comes in to play.
When to Use the VSC off Button
A very common warning light to come on on your dash is the VSC off light. It is the vehicle stability control light. It indicates the activation of traction control. Using your VSC off button, you can turn off or reset the light depending on how you want to use it.
The VSC system is a technology designed to keep your vehicle under control in emergency situations such as when your car is fishtailing out of control. For example, it will apply breaks to one of the wheels in order to maintain traction.
You use your VSC off button in a few different scenarios. Hard braking is one of the most common situations when you might see the VSC light come on. Another common one is when you switch from drive to reverse, especially if you switch at a high speed. This can be particularly dangerous if your tires are wet. If you do experience these scenarios, you should use your VSC off to reset the light.
On the other hand, you might have a light that comes on when your wheels are spinning for no reason whatsoever. In this case, you probably just need to turn your traction control off or turn off the ABS (stability control) system.
You probably know when they’re activated because it can make your steering wheel vibrate or if you have the “off” ABS button.
Is it Safe to Drive with the Check VSC System Light On?
Many drivers are a bit nervous when they see the Check VSC system light on their dashboard. They think that it is a warning light that means they’re not safe to drive. However, it often means that the system just needs to be reset.
The stability control system is a safety feature included in many modern vehicles. Since it is a safety feature, you might be wondering what the problem is if the light comes on.
The Check VSC system light means that the system has detected an issue that might be dangerous. Some of the possible issues include low or high tire pressure, a loose or damaged wheel, a defective hydraulic brake master cylinder, a loose or jammed brake pedal, and failed steering angle sensor.
A few mechanics believe that the light may come on when they are not using it, or it may come on only when the steering wheel and the car are in motion. In order to reset it, they say, turn off the engine, turn the wheel left and right a few times, and restart the engine.
Whether or not you should trust this method is up for debate. The NHTSA clearly states that the light is a warning that you need to check the safety systems. Your safest bet is to bring it into a service center for checking.
How to Reset the VSC Light
The Vehicle Stability Control System (VSC) is a feature of many Subaru vehicles, which helps to maintain control when the driver encounters a situation that requires the additional of wheel spin or braking. When engaging the VSC system, the light on the dashboard will lit up. This indicates that the VSC system is currently engaged. If the light is lit up and the car is still driving smoothly, then the VSC is on.
Also, it is possible that the VSC light will turn off, but the VSC system is still working. This indicates a fault in the system. In this case, the driver should have the vehicle checked by a qualified Subaru technician.
There are a number of faults in the system that result in the VSC light being lit up, and as a consequence, the VSC system being switched off when it should not be.
The most common cause of the VSC light being lit up is when the battery is flat. If the driver has been out in the car for a long time and then returns and finds the car has gone flat, the VSC system will be activated.
As can be seen from above, a fair amount of care and maintenance is required after the car has been purchased.
Owners need to keep the car in a good state of repair if it is to retain its value and if it is to provide them with safety and reliability.
However, don’t be put off by the amount of maintenance, because many people enjoy working on their vehicle. It’s a shame that we don’t drive through the countryside just looking at all the changes and the beauty of the seasons.
We’re constantly too busy, and the thing we drive around in is just something we depend on. It’s fortunate that car ownership doesn’t just mean using your vehicle to get from A to B. There is a practicality about cars that means you might have some appreciation for them. We’ll always need a car, so make the most of it while you have it.
