What is ASC


ASC is a brand of Traction Control. It reduces engine power if the wheels begin slipping under heavy acceleration.

BMW used this brand for their first traction control system, which was replaced with ASC+T. ASC+T also brakes the slipping wheel to more quickly regain traction. Later ASC+T was replaced with DSC, their stability control brand.

Traction control systems have been replaced by more comprehensive stability control systems (mandatory on new cars in many countries), which ensure the car is always pointing in the direction you are steering.

I have a 1999 BMW 323I five speed, but when ever I shift to 3rd gear the asc light comes on and the car will not pick up speed


ASC light is part of the ABS system. ASC means slip control system.When this light comes on because it is integrated with the DME or for a better term ECM (control module) It commands trottle reduction. The ASC uses the wheel speed sensor your only fix is get the ABS or (brake inspection) look at The computure engine management thinks you are slipping.

I have bmw 530d and abs asc and other 1 its on after 2 miles i been on service and mecanic sed presure sensor interference,i change presure sensor and delithed all cods but its on agan.


Hi.The problem of your car sounds like a faulty ABS/ASC control unit. It is the common problem of this model cause the Control Unit is too close to exhaust manifold resulting to dammage internal parts of ABS/ASC control unit. But although this is the common problem of your car, I still suggesting you to re-hook up diagnostic tools and double check the condition of wiring harness, plug connections and power supply of related fault codes you will retrieved and if the problem still existing then I recommend you to replace the ABS/ASC Control unit and do Coding for new control unit.
I hope this tip will help you to solve your problem.
Thanks

ABS and ASC warning lights stay on 2000 530d


Check to see if your brake pads and rotors are in good condition. Or if you have replaced the pads yourself and have not reset the wheel sensors this would cause the ABS Antilock Brake System light and the ASC Automatic Stability Control light to stay on as the ASC uses the ABS brakes with computer assistance to control the car

Asc trac control not available light comes on


the ABS controller (the box that hooks up to the ABS pump) is bad.
There are 2 plugs. The top one has a sort of slider that you pull up to disconnect the plug, the bottom one is a bit tricker, but keep fiddling, it will come off. The next fun part is the 4 FEMALE TORX fasteners that hold the box on. You'll need this socket (it's a T5 female IIRC) to remove the box. Be careful fishing it through the brake lines. Remove the unit and send it to ASI inc. 423-921-9085,
212 e. Washington St, Rogersville TN, 37857. They will rebuild your unit for $55 and a lifetime guarantee, and you can drive the car while the unit is out being serviced. You'll have the ABS, CHECK ENGINE, ASC/TRAC NOT AVAILABLE AND LOW BRAKE FLUID lights in, and your handbrake light will also be gone. When you get the unit back, disconnect the battery reinstall the unit, connect the batter and erase the codes (I cleared mine with a cheapo PepBoys model) PROBLEM SOLVED.! These ABS controllers are cheap POS parts made in the Phillipines....I'd settle for LUCAS any day.

My ASC+T Indicator Lamp lights and car can't move...


When your ASC light is on this is to let you know your Automatic Stability Control system is switched off press the ASC button Till light is off /ASC is on this works with your rev limiter and should stabilized your idle. If the problem persists have your throttle control unit checked as this can trigger the ASC light as well and may also activate the ABS light if not fixed

Asc alwayes on after i changed he ABS box


hello mazeer, when you changed the abs/dsc/asc control unit did you have the replacement coded to your vehicle. Also after changing to another unit, it is usually necessary to recalibrate the sensors. if your vehicle does not recognize the replacement unit, you will have a constant warning lamp. Most dealers/shops charge appr. 1hr to code and calibrate the control unit.

My car is bmw 525i 2000 model asc sensor alwayes on after i change abs box


if you changed the asc module, the module has to be programmed/coded after replacement. If it was a new part there should be no problem programming the new control unit. I would recommend taking the vehicle to the dealership to allow them to program the control unit.If you have access to the programming don't forget to take the asc module out of "end of belt line mode" and most likely the steering angle sensor will have to be aligned
