What Does the Service StabiliTrak Message Mean?

Today, modern cars are equipped with advanced systems that enhance the driving experience, such as StabiliTrak, an electronic stability control system designed for GM and similar systems for other brands. However, when the Service StabiliTrak warning appears on the dashboard, it can be confusing.

Stabilitrak helps you stay straight by monitoring and adjusting your vehicle’s steering, braking, and traction. This system uses sensors to determine the position of the steering wheel and tires and checks that they match your vehicle’s direction of travel.

In this guide, we take a closer look at Service StabiliTrak systems and provide expert tips on what to do when this warning light comes on. We also discuss how to reset the light when appropriate.

What is StabiliTrak?

StabiliTrak is GM’s proprietary electronic stability control system, developed in partnership with Delphi Automotive and first introduced in 1996. The system is designed to prevent loss of control by automatically adjusting the vehicle’s brakes and engine power when necessary.

Whether navigating icy roads, swerving suddenly, or driving on uneven terrain, StabiliTrak helps maintain vehicle stability and prevent dangerous skidding or rollovers.

StabiliTrak improves vehicle stability by monitoring several vital inputs, such as steering wheel angle, yaw rate, and wheel speed. By constantly analyzing these factors, it can quickly detect potential instability and intervene to help you stay in control.

This system has become a hallmark of Chevrolet’s commitment to safety, underscoring its dedication to delivering secure, dependable vehicles.

According to the Insurance Institute for Highway Safety, electronic stability control systems such as StabiliTrak reduce the risk of fatal single-vehicle crashes by up to 38%.

How does StabiliTrak technology work?

StabiliTrak is a safety feature included in every GM vehicle, which is GM’s version of electronic stability control (ESC). StabiliTrak helps keep the car safely on the road by monitoring and adjusting the steering, braking, and traction of the vehicle.

The system uses sensors to determine the position of the steering wheel and tires and checks that they match the direction the vehicle is moving. If the system senses that the vehicle is out of control, it makes automatic adjustments to bring it back under the driver’s control by applying brake pressure to certain wheels, encouraging the car to straighten out.

StabiliTrak is activated when the vehicle sensors detect a difference between the driver’s intended path and the direction the vehicle is actually moving.

The system can activate in a split second and helps the driver avoid a potential spinout or accident. StabiliTrak is always on and monitoring the driver’s driving, keeping the driver in control and on the road.

If the system senses that there is a problem, the driver will see a warning message on the dashboard.

What does the service StabiliTrak light mean?

The “Service StabiliTrak” warning light indicates a problem with the stability control system. The StabiliTrak system is not the same as the traction control system, which only applies when the car is in motion and fishtailing.

The “Service StabiliTrak” warning light can appear when the car is in motion or idle. It can be caused by a malfunctioning sensor, a disabled system, or a bad signal. If the warning light comes on, it is not recommended to drive the vehicle until the problem is fixed.

However, the message may appear when driving on a slippery surface, which is evidence that the system is working correctly.

To fix the problem, the driver should pay close attention to the warning light and try to figure out what could be wrong. It is recommended to take the vehicle to a mechanic to diagnose and fix the problem.

Once the problem is fixed, the warning light can be reset. If the StabiliTrak warning light comes on, the Traction Control System will be turned off, and the driver will need to drive accordingly if in certain conditions.

Stabilitrak vs. Electronic Stability Control

Stabilitrak is a traction control system that is more advanced than Electronic Stability Control (ESC) systems. Traction control and stability control are two different ideas, but both can be lifesaving devices.

Traction control stops wheelspin by applying brake pressure and controlling the throttle, while stability control is an evolution of traction control that bites one or three wheels, or even cuts the power, to send a car in an intended direction.

Stability control often cuts power and brake wheels to help maintain control of a vehicle when the tires lose grip or can’t find traction.

Are StabiliTrak and traction control systems the same?

StabiliTrak and traction control are not the same, although they both work to improve traction and stability.

Traction control is a technology that prevents the wheels of a car from slipping, especially when accelerating on slick surfaces.

StabiliTrak, on the other hand, is a more comprehensive system that uses sensors to monitor the vehicle’s speed, steering angle, and yaw rate to maintain stability by adjusting engine power and applying brakes to individual wheels.

StabiliTrak also works with other vehicle systems, such as traction control and the anti-lock braking system (ABS), to offer a complete solution for enhancing vehicle stability and handling.

While stability control is just traction control with more vehicular education and better tools, StabiliTrak is more advanced than ESC systems.

StabiliTrak helps the car go in a straight line once it is already moving, using sensors to determine the position of the steering wheel and tires compared to the direction the car is moving.

If the car begins to fishtail on a slippery road, StabiliTrak will kick in to help correct the course and bring the car back to its intended route by applying brakes to individual wheels and altering engine power.

What causes the service StabiliTrak warning to come on?

The “Service StabiliTrak” warning light may illuminate for several reasons. The most common causes of the warning light include problems with the StabiliTrak system, such as sensor or control module failure, a brake system issue, such as low brake fluid or a broken brake control module, and issues with the traction control system.

However, there are aspects beyond these systems that could cause the malfunction. The most common causes of a Service StabiliTrak message include:

• Bad throttle position sensor
• Defective ABS sensors
• Malfunctioning steering angle sensor/steering wheel position sensor
• Old or corroded spark plugs
• Bad fuel pump
• Engine misfire
• Issues with the Active Fuel Management (AFM) system
• Defective brake switch
• Bad tire pressure monitor sensor
• Malfunctioning body control module
• Use of E85 fuel

It’s also possible that a bad fuel pump is causing the issue, even though the StabiliTrak isn’t part of the fuel system.

For this reason, it’s important to monitor all the symptoms that the car is exhibiting to make a proper diagnosis. If there are other things going wrong at the same time, it will be much easier to diagnose.

Symptoms of a Bad Service StabiliTrak System

• Warning message: The illuminated StabiliTrak light on the vehicle dashboard is one of the clear symptoms of a bad StabiliTrak System.
• Trouble Code: Your Vehicle computer may have triggered a trouble code relating to speed sensor failure, steering wheel sensor failure, and ABS fault.
• Reduced acceleration or power: In certain conditions, a bad StabiliTrak System may lead your car to lose acceleration or power, making it difficult to drive.
• Strange noise: When this system fails, you may hear strange sounds from the vehicle compartment.
• Limp mode: The vehicle computer may turn on the limp mode when it recognizes a problem with your service StabiliTrak System.
• Reduced stability control: Your car may be more prone to understeering, oversteering, or skidding, leading to loss of control and possible accidents.
• Hard starting conditions: When your service StabiliTrak System has failed, your car will be hard to start or may not start at all.
• Loss of traction control. The vehicle may experience reduced traction control or may become difficult to handle, especially in slippery or wet conditions.

Can you drive with the service StabiliTrak warning light on?

The “Service StabiliTrak” warning light indicates a problem with the stability control system, which helps maintain the vehicle’s traction and stability. While it is safe to continue driving when the StabiliTrak light comes on, it is not recommended.

The systems that would normally help control the car in a sliding situation are not working, so the driver should drive carefully when necessary. If the traction service light is also on, there is likely an issue with the system, and the driver should have the vehicle serviced.

It is important not to disregard the warning notice, as it indicates that there is a problem with the car’s stability control system. The light can indicate a variety of problems that need to be addressed before the traction control system operates correctly. If the StabiliTrak light stays on, the driver should have the vehicle serviced.

If the StabiliTrak light comes on due to a computer glitch or software failure, the light can be easily reset without having to visit an automotive shop.

However, if the light comes on due to a malfunctioning system controller, the computer in the vehicle may need to be reset, which may require a visit to the dealership where the vehicle was purchased.

How to Reset Service StabiliTrak Message?

Resetting the Service StabiliTrak message is a simple process that can be done without a scan tool. Here are the steps to reset the Service StabiliTrak message on most Chevy and GM vehicles:

• Check the StabiliTrak button. When manually pressed, the light stays on.
• Consider weather systems and road conditions. If there is a reason for the system to be automatically disarmed, that could be the reason the warning light is on.
• Turn the steering wheel clockwise. If the light goes out, the StabiliTrak system is probably fine. If the light stays on, continue with the following steps.
• Park the vehicle. Go away and do something else for about 15 minutes. This time gives the system a chance to reset itself.
• Restart the vehicle. If the message is no longer displayed, you do not need to service the vehicle. Otherwise, it’s time for a full diagnosis.

Another way to reset the StabiliTrak system is to turn off the car and let it sit for a few minutes. To turn off the StabiliTrak system, press the ESC button and hold it for six or more seconds. The sound of a buzzer indicates that the StabiliTrak is off.

It is important to note that resetting the Service StabiliTrak message does not fix the underlying issue. If the warning light turns on again, it is important to address the issue promptly to ensure safe driving conditions.

If the owner’s manual does not provide a procedure for turning off the Service StabiliTrak message, or if the message turns on again after trying to reset it, it is best to take the vehicle to a qualified mechanic. They will have the necessary tools and expertise to diagnose and fix the issue.

Difference Between StabiliTrak System and Traction Control System

While traction control and StabiliTrak are different systems, they both exist for improving vehicle traction and stability. However, they have different methodologies and functions to achieve this.

The traction control system works on the premise of lessening the amount of acceleration of the wheels, and it has been used primarily on slick or slippery surfaces. In the example of slippery surfaces, the traction control system will limit the acceleration of the rear wheels by imposing limiting engine power or braking at each of the rear wheels.

The StabiliTrak system is an advanced stability control system. The purpose of the StabiliTrak system is to provide for improved stability of the vehicle in various driving conditions.

As previously stated, the StabiliTrak system improves stability by utilizing data from the additional sensors. The onboard sensors capture the necessary data on aspects of the vehicle, such as speed, steering angle, and yaw rate.

Once the vehicle speed, steering angle, and yaw rate are calculated and display potential instability with the driving condition, then the StabiliTrak system can improve stability through modulating engine power or by controlling the brakes at each wheel.

In some vehicle systems, these two systems operate separately from each other. In many vehicle systems, the two systems work together, contributing to one integrated stability control system.

There can be problems with both the traction control system and the electronic stability control system from electrical issues such as faulty wiring, bad sensors, or faulty electrical components.	StabiliTrak System
