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.

It sounds like a traction control system and is known as “Automatic Stability Control” (ASC). They are made to improve operating stability, particularly when cornering and accelerating. The light is normally supposed to turn “OFF” quickly after the ignition is turned on.
If the warning light is on:
When the indicator light does not turn off after the engine has started or during routine operation, there is a problem.
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.
How does BMW ASC operate?
ASC leverages the diagnostic capabilities provided by the ABS wheel sensors in addition to using them to track the rate of wheel rotation. The electronic “brain” of the engine compares the speeds of the front and rear wheels to determine wheel spin.
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 information 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 Lexus’ ASC stand for?
The Lexus LFA supercar is famed for its tremendous soundtrack, which is the absolute definition of spine-tingling loudness, whether heard from within or outside the car.
The V10’s acoustics were tuned to deliver an exhaust note resembling that of a Formula 1 car, and a trio of optimized sound channels were used to fill the interior with thunderous intake and exhaust noises, so these characteristics weren’t an afterthought.
To increase the joy of driving, similar elements have been added to the Lexus IS line.
For example, the IS 250 F Sport has an Intake Sound Creator to produce a sportier engine note. Similar to the LFA, the Intake Sound Creator amplifies the natural vibration of the intake pulse using a specific damper (see diagram of intake tubing below), then directs the amplified vibration into the cabin as an appealingly athletic intake roar.
The IS 300h improves the driving experience entirely through a new method. Active Sound Control (ASC), a new technology that is a first for Lexus, adds audio to the engine sound through a dedicated loudspeaker concealed below the dashboard. The exhilarating sound of acceleration and deceleration is delivered by the volume-adjustable ASC even when the hybrid system’s engine is turned off and the vehicle is just using its electric motor for propulsion (see below). However, when Eco or EV mode is chosen, the audio feed is immediately turned off.

What does my car’s ASC button do?
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.
What does Mini Cooper’s ASC stand for?
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 ASC in a Jaguar stand for?
29.06.2021, Glossary. On Jaguar and BMW vehicles, the ASC (Automatic Stability Control) technology has been implemented. In 1997, it initially debuted. It limits the engine’s output, which aids in preventing slippage.
The meaning of an ASC light
System ASC Service When a car’s required light comes on, something is wrong with the car’s stability, traction, ABS, or 4WD. Another interpretation is that they are all crippled. Given that the ASC system is linked to the ABS and your vehicle’s traction, it needs to be serviced.
How does ASC t function?
Based on the inputs from the wheel speed sensors, the ASC+T control calculates the degree of slip. The control module calculates the vehicle’s speed by averaging the speeds of the two front wheels. To assess the amount of slip, the front and rear wheel speeds on each side are tracked.
When is ASC switchable off?
It may feel like the engine is bogging down when accelerating on slick surfaces. If you’re participating in AutoX or track racing, you should turn it off. The wheels won’t be independently braked by ASC.
Why does the traction control indicator on my BMW keep flashing?
The traction control light may indicate an issue that isn’t yet “hard coded,” or a condition that won’t go away permanently, if it illuminates sporadically. Use particular caution on slippery roads if a light is flickering since it could also indicate that the system is not entirely functional.
When traction is lost, such as during snowy or rainy conditions, many traction control systems may turn on the warning light. Usually, the light appears when the system steps in to keep traction. To become familiar with how your traction or stability system functions, it’s a good idea to study the relevant part in your vehicle’s owner manual.
The traction control system has been turned off and there is no traction control accessible if the traction control light turns on and stays on without blinking. The driver information center may even send out a message informing the motorist that the traction control system has been disabled and urging them to drive carefully, especially in wet conditions and when dealing with ice and snow.
Having the car correctly diagnosed at a reputable repair facility is the only method to effectively treat either of the aforementioned concerns. Always request a complete computer system scan from the repair shop. The light may not always be caused by a problem with the traction control system. The traction control system may occasionally first exhibit symptoms of an engine management system issue, such as an intermittently bad throttle position sensor in the electronic throttle control.
The powertrain system’s fundamental mechanical parts also need to be thoroughly evaluated. Wheel slide can be caused by anything that would result in a jerky or rough application of power, which makes worn drivelines, axles, and constant velocity joints questionable. Wheel spin can be caused by even a forceful transmission shift or a seriously misfiring engine, which will turn on the traction control light.
