The Service Stability System of a vehicle goes by different names. Sometimes it is called the Vehicle Dynamic Control, the Vehicle Stability Control, the Dynamic Stability Control, or the Electronic Stability Control. Whichever you call it, it always bothers us when this warning light comes on. So, what does it mean when the Service Stability System warning light flashes or flickers?
The Service Stability System is a computer system of your vehicle that detects when you seem to start skidding. It will automatically apply the brakes to allow you to steer in the correct direction safely.
Read on to learn more about your vehicle’s Service Stability System, including why its light comes on and how to fix it.
Service Stability System [Causes and How to Fix this Warning Light]
Refers to the Vehicle’s Computer System That Detects Skidding
The Service Stability System refers to the computer system of your vehicle that detects when your vehicle tends to start skidding. It will automatically apply the brakes, allowing you to steer safely in the correct direction.
Compares the Steering Wheel Angle with the Actual Direction Where the Vehicle Is Going
This computer system works by comparing the steering wheel angle with the actual direction where the vehicle is going. It also takes into consideration the road speed of each wheel.
Automatically Adjusts the Brakes
If the system detects a lateral slip in the tires, it automatically adjusts the brakes. It also adjusts the throttle differential and/or the suspension to completely bring back the vehicle into line.
Works on Wet or Icy Pavements and Dry Ones
What’s great about this Service Stability System is that it works not only on wet or icy pavements but also on dry ones. Impressively, it is capable of detecting skids more quickly than you do. It is possible to correct your driving even without you knowing it.
Flashing Service Stability System Warning Light
So, how would you know if it did correct you? The Service Stability System warning light on your dashboard will flash or flicker as you drive. Some vehicles even emit a beep when this happens.
Does Not Enhance Car’s Performance
However, you should remember that the Service Stability System does not enhance performance. Most of all, it does not replace your safe driving practices.
An example of this is if you are forced into an extreme steering correction to avoid a deer that suddenly appears in front of you. If you violently maneuver the car, it will most likely exceed the system’s limits.
Not Capable of Increasing Traction
The Service Stability System is also not capable of increasing traction. At the same time, it does not make you corner faster.
Service Stability System Components
The Electronic Control Unit (ECU) is the brain of the Service Stability System. It also controls other vehicle systems such as the following:
- Climate Control System,
- Traction Control System, and
- Anti Lock Braking System (ABS).
The Service Stability System consists of several sensors. These include the following:
- Steering Wheel Angle Sensor
- Wheel Speed Sensor
- Lateral Acceleration Sensor
- Yaw Rate Sensor
- Other Sensors
1. Steering Wheel Angle Sensor
The Steering Wheel Angle Sensor measures the position angle and rate of turn of the steering wheel. It is positioned in the vehicle’s steering column. It identifies where you want to steer.
2. Wheel Speed Sensor
The Wheel Speed Sensor refers to a type of tachometer. It is a sender device that reads the speed of a car’s wheel rotation. In essence, this sensor detects how fast your wheels are spinning.
3. Lateral Acceleration Sensor
The Lateral Acceleration Sensor measures the g-force from a turn and then sends information to the ECU. It detects how fast the vehicle is moving in a sideways manner.
4. Yaw Rate Sensor
The Yaw Rate Sensor detects whether the vehicle tends to spin around the vertical axis. It assists the Service Stability System in determining the driving-dynamic state of the vehicle. In essence, this sensor detects how much the vehicle is turning.
5. Other Sensors
Longitudinal Acceleration Sensor
There are Service Stability Systems that also feature a Longitudinal Acceleration Sensor. This sensor determines the forward and backward acceleration of a car.
This includes not only normal acceleration but also decelerating braking forces. This sensor sends information about road pitch.
Roll Rate Sensor
Another type of sensor is the Roll Rate Sensor. Some Service Stability Systems have this to enhance error corrections coming from the Wheel Speed Sensor, the Lateral Acceleration Sensor, the Yaw Rate Sensor, and the Steering Wheel Angle Sensor.
Service Stability System Light on Different Car Brands
The Service Stability System Light on a Cadillac is added to your vehicle’s anti-lock braking system.
It works by determining if your Cadillac loses directional control as you drive it. This system consists of several types of sensors. Some of which are the Yaw Sensor and the Steering Wheel Position Sensor.
When your Cadillac senses that you are losing directional control, it automatically applies brakes to specific wheels. This is in its attempt to correct the vehicle’s position if it seems to be sliding or losing traction.
Similarly, the Service Stability System light on a Buick flashes or flickers to alert you that it is currently working actively.
Your Buick might be sensing that you are in the wrong direction and that there is a risk of skidding. It will automatically apply the brakes to one or two wheels to help you steer in the correct direction.
The Service Stability System of a Buick has several types of sensors. But the most common cause for the system light to flash or flicker is when there is a faulty steering wheel position.
What Does the Service Stability System Light Mean
The Service Stability System has been around since 1983. But it was only in 2012 that all cars manufactured and sold in the United States were mandated to be equipped with this system.
There are different reasons why the Service Stability System light illuminates. These include the following:
- Your Vehicle’s Service Stability System Is Doing Its Job
- Service Stability System Malfunctions
1. Your Vehicle’s Service Stability System Is Doing Its Job
As we all know, when a warning light on our vehicle’s dashboard starts to flash or flicker, it tends to bother us. This is because we know that there’s something wrong with our car and it needs immediate attention.
Active Service Stability System
However, it is different in the case of the Service Stability System of a vehicle. When this system flashes or flickers, it is currently working actively. Suffice to say that it is doing its job efficiently.
When your car’s Service Stability System detects a risk of skidding, it will gently apply the brakes automatically. It will also guide you to steer safely in the correct direction.
Prevents the Risk of Skidding
When your vehicle does this, the warning light on your car’s dashboard will flash or flicker. This then indicates that it is assisting you in preventing the risk of skidding.
In some vehicles, the warning light flashes regularly. There are, however, vehicles in which the warning light flickers fast. Whichever manner it flashes or flickers, it is communicating the same thing.
Now, when the warning light flashes or flickers, what does it mean? It means that you have restored full control of the vehicle, and everything is in place. You will also notice that the Anti Lock Braking System light has come off too.
2. Service Stability System Malfunctions
A flashing or flickering Service Stability System Warning Light may mean it is doing its job efficiently. But it may also mean that the system is malfunctioning. In which case, you will notice the continuous flashing on startup.
The best way to address this is, first, to not panic. Next, make sure to bring your car to a service center or your trusted mechanic. This way, they will be able to address the issue immediately.
Again, what does it mean when your car says service stability system? The Service Stability System detects when your car starts to skid. Then, it gently applies the brakes to help you drive in the right direction.
What Causes the Service Stability System to Flash Continuously on Startup
If the Service Stability System flashes continuously on startup, it is malfunctioning. Since this system consists of different sensors, one or two may be faulty. It is even possible that more sensors are damaged.
Failing Wheel Speed Sensor or the ABS Sensor
In most cases, the wheel speed sensor or the ABS sensor is the culprit. In which case, you will also notice the ABS warning light illuminating. But it is not uncommon that they get faulty. Over time, they also get dirty, or their wires wear out. This occurrence, however, is easy to fix.
Faulty Steering Angle Sensor
Another issue triggering the Service Stability System warning light is when the steering angle sensor gets faulty.
