One of the most popular factory-installed optional extras is the BMW Motorrad ASC (Automatic Stability Control) rider aid system. This is because BMW Motorrad’s anti-slip control system restricts the amount of engine drive torque delivered in accordance with the state of the road’s surface and, therefore, the friction coefficient.
This prevents rear wheel spin and improves power transmission, considerably raising active riding safety in risky circumstances like riding in the rain. You can turn off the system instantly, even while moving, if electronic regulation is not necessary, such as on a racetrack.

Since I assume you don’t have an owner’s handbook, you should go buy one. Since users on this site occasionally make mistakes, if you already have one, it’s quite obviously answered there, and you should reference it for any fundamental questions you have. A manufacturer’s statement is preferable.
ASC stands for traction control, however. When the light is off, ASC is in operation. If the light is steady on, it indicates that your ASC is off, or not doing anything. It means it started working a little if it flashes while you’re driving.
The fact that ASC would fully cut power if it detects wheel spin is unpleasant. This can occasionally be a real pain. For instance, if you pump the pedal to try to squeeze in with the 70 MPH traffic on that 5 foot merge from Treas Island onto the Bay Bridge east, your wheels will start to spin a little. ASC will, regrettably, cut your throttle. When that occurred, I was going in front of a Mack truck, and it was terrifying to watch it come crashing down as my car lost power.
Automatic Traction Control and Stability Control (ASC-X)
Automatic Stability Control + Traction (ASC + T), a BMW-only technology that was first featured on the BMW 7 Series, is a suspension control system that helps minimize engine output by ensuring that the car can move or accelerate without experiencing wheelspin.
If necessary, the system can be turned off.
How does it function?
ASC-(Automatic X’s Stability Control and Traction) advantages include:
* On a slick surface, the wheels no longer block when the accelerator is removed.

The ASC button should be pressed once to turn it off and once again to turn it back on. I’m aware that turning off ASC turns off the traction control, but I’m not sure if it also turns off the “fake LSD” behavior (does anyone know?).
The behavior changes if the ASC button is held pressed for 10 seconds. Instead, until the car is turned off and then back on, ASC is disabled. This apparently disables traction control on specific BMW models while maintaining the “fake LSD” characteristic. Does this apply to e46s?
NOTE: Although there are two levels of “off” for the DSC button, that is NOT what I am referring to. Instead, I am referring to the ASC button, about which everyone seems to agree that there are only two possible states.
My ASC button: What does it do?
Hey, I just acquired an e36, and it has an ASC button directly above third gear. After pushing it, I believe nothing happened (nothing lights up or anything). What is the ASC switch supposed to do, please?
I think that’s traction control, but I’d think something would light up because every other car I’ve seen with it has a dash light.
Since it isn’t the car’s speed, age, or anything else about it that matters, congrats to those of you who hold on to an old car and appreciate it for what it is today. Instead, it is the enjoyment element, and the majority of us simply adore our old e36 M3s.
Mine also doesn’t light up, and Blub is out. Traction control will turn on automatically when the automobile is turned on. Turning off the traction control requires just one button press. Once more, it will be on. However, the automobile turns on each time it is started.
run the machinery You’ll notice if you run the car through the gears quickly after hard starting it, then click the button and do it again. Alternately, you can try a burnout, turn it off, and then you’ll be able do a one.
How does the BMW DSC operate?
We have had a lot of inquiries concerning the capabilities of dynamic stability control now that snow, ice, and other winter messes are appearing all over the planet (DSC). A brief summary of each of its functions and the fundamentals underlying them can be found in the information that follows. We sincerely hope that the material provided is helpful and helps you find some of the answers to your inquiries. The data presented here applies to the more recent models of DSC-equipped vehicles.
There is no need to touch any buttons at startup because DSC is ON by default. Wheel spin, yaw rate of the car, and other features are all detected by DSC using a variety of sensors. It may apply the brakes as necessary, reduce engine power, and, with Active Steering, it can make slight steering corrections to better maintain control of the vehicle. In plain English, all of the nannies are turned on by default and help to prevent the automobile from spinning out. A warning light will flash in the instrument cluster when DSC is intervening.
DTC (Dynamic Traction Control) is a DSC sub-function in select vehicles. By briefly pressing the DTC button, it is turned on. This feature has been activated, as shown by a light in the instrument cluster. DTC DOES NOT cut the engine’s power; instead, it permits the wheels to spin and raises the angle at which the system will start applying the brakes (thereby doing away with the yaw rate sensors). This system feature was created to give the driver the ability to spin the wheels in order to navigate through snow, ice, and other conditions that call for wheel spin. While some sensors are turned off, others are still in operation. In dry weather, this function also offers a sportier driving experience while serving as a modest safety net. After experimenting with this system on the track, DTC would still cut in and apply braking, making it difficult to fully extend the rear end while letting you continue to drive through at full throttle. Similar to DSC, a blinking caution light signifies that the system is taking action.
By pressing and holding the DTC button for 3 seconds, DSC/DTC can be switched OFF. The nannies are now off and you are on your own, so stay within your capabilities! The danger signal light (as shown above) will continue to be lit in the instrument cluster.
The e-Diff is a feature of the DSC system that does operate even when everything is turned off. This is included in 1 series vehicles and 3ers made after March 2008. With the introduction of the most recent 7 Series and 5 Series models, vehicles with xDrive are now equipped with both this and the capability to vector drive power to the outside wheel by applying brake pressure. In essence, the e-Diff imitates the idea of a limited slip differential (LSD). By applying brakes to the rotating wheel, it achieves this while also transferring more power to the wheel with superior traction. If you want to, you can remove strips from it. In DTC mode, this feature is likewise operational.
It’s crucial to keep in mind that no technology, no matter how smart, can overcome the laws of physics and driver competence, even though DSC and its companions give you an extra level of safety. In other words, use caution when driving in poor road conditions and drive safely within your capabilities.
What does my mini’s ASC button do?
Automatic Stability Control, or ASC Rear brakes are applied by ASC if the rear wheels spin more quickly than the front wheels using speed sensors at each wheel and throttle position. To increase traction, it can also close the throttle valve and turn off specific fuel injectors.
What does my car’s DSC button do?
Describe DSC. The suspension control system known as DSC, or dynamic stability control, extends beyond the functions of ABS, Cornering Brake Control (CBC), and Automatic Stability Control (ASC). Through a variety of sensors, it operates by keeping track of the individual wheel speeds, yaw rate, and longitudinal and lateral acceleration.
This safety net on your automobile is called Dynamic Stability Control (DSC), and it is a feature of BMW. Every time you start your BMW, it immediately activates.
The steering angle sensor, engine speed, throttle position, brake pedal position, and force are all inputs to the dynamic stability control module. All of this data is supplied into the DSC process and control module.
The ideal driving situation is continuously calculated by the DSC computer and compared to the actual situation. If the vehicle oversteers or understeers, the calculated ideal deviates from the measured status, and DSC will intervene via the engine management system within a few milliseconds by either applying brakes to different wheels, cutting fuel, and/or a few other methods that are too detailed for this brief presentation.
A setting called Dynamic Stability Control can keep your BMW operating within the bounds of physics. The bulk of the time, you want a controlled environment where you can keep the car on its intended course. If power exceeds grip, the DSC system will activate the brakes individually if necessary to prevent a wheel from slipping.
If it notices wheel slide, Dynamic Stability Control may even reduce the power to the wheel. It becomes considerably more complicated when the all-wheel drive system is added. DSC basically means that you shouldn’t drive with your tail out or do donuts in the snow. By observing the yaw of the vehicle, the input from the steering wheel, and the pressure applied to the gas pedal, it can detect when you are ready to spin the vehicle and intervene once again.
DSC is a fantastic safety feature in any vehicle and has and will continue to save many vehicles and their occupants.
ASC control unit: what is it?
When driving in challenging conditions or when performing emergency maneuvers, the Active Stability Control (ASC) technology aids drivers in maintaining control. The control unit, which collaborates with the anti-lock braking system of the car to provide appropriate traction, receives alerts from many sensors that continuously monitor the amount of available wheel traction. ASC warns the control unit if it notices any slipping or loss of control, and the control unit then applies the brakes to particular wheels to maintain the car going in the driver’s intended direction.
