ASR: your car's anti-slip system

The abbreviation ASR comes from the English language and stands for Anti-Slip Regulation. This helps to minimize the loss of traction on the drive wheels of your vehicle. Thus, this electronic equipment allows for better road holding and increased safety, especially in hard-to-reach places with snow or ice.

🚘 How does the ASR system work in your car?

ASR stands for anti-slip system your car is equipped. This system prevents loss of wheel traction and, in particular, facilitates the startup and acceleration phases. In practice, this system brakes a spinning wheel to give the other wheel full access to the engine torque.

Thus, it allows drive safely on a snowy, icy road or get out of a rut on the sidewalk or dirt road.

Therefore, ASR focuses on a pair of motors your vehicle by making it accessible for better wheel grip. Thus, it allowsquickly adjust the trajectory of your car and avoid losing control on slippery roads.

This security system is installed on most modern cars, and not on any particular type of vehicle. Indeed, it is just as useful for a city car as it is for an SUV when those vehicles are in difficult road conditions. This greatly reduces the risk of an accident or collision when the vehicle loses traction.

⚡ What is the difference between ASR, ESP and ABS?

These 3 acronyms represent 3 separate safety systems, but they complement each other completely to ensure that your vehicle is as safe as possible on different journeys. They all play a role in the wheels of the car. Thus, each of them responds to a specific role:

• L'ASR : It works at the engine torque level and improves wheel traction. It only activates when the wheels are spinning.
• The ESP : it plays a role in wheel slip, not wheel slip. The electronic stability control ESP consists of several sensors that calculate the wheel speed. In this way, it adjusts the vehicle's trajectory to prevent wheel skid and therefore loss of trajectory, mainly on winding roads with very tight bends.
• ABS : This protective anti-lock braking system will prevent the wheels from locking, especially when you press the brake pedal sharply or quite hard. This is especially useful when you are driving on a road with poor traction, as it prevents the vehicle from slipping.

⚠️ What are the symptoms of ASR failure?

It may be that your ASR system is faulty or has an electronic problem. In this case, you may be informed by the following events:

1. The wheels will turn : This is especially important when driving on roads covered with snow or ice;
2. Loss of traction : if you often drive in mountainous areas, you will feel a weak traction of the wheels;
3. Le dashboard display message : it will inform you through a signal that the ASR is defective. In some cases, this can also cause the ABS warning lamp to come on.

As soon as you develop these symptoms, you will need to see a professional as soon as possible, because a failure of the ASR system could put you in danger on the road. Indeed, loss of traction significantly increases the risk of an accident or loss of vehicle control.

💶 How much does it cost to repair an ASR system?

The ASR system is an electronic device equipped with sensors: therefore, a self-diagnosis must be performed to check its operation. Using the diagnostic case, the mechanic will be able to retrieve the fault codes stored by your vehicle's computer and correct them.

This is a maneuver that can 1 to 3 hours of work depending on how quickly the problem is detected. On average, it costs from 50 € and 150 € in garages.

Anti-skid control (ASR) is much less well-known than ESP or ABS, but its role is just as important. In fact, if your wheels weren't equipped with this technology, they would skid much more and could get stuck more easily in certain conditions and on certain types of roads.
