Dsc light stays on just wana no what to do

If the light stays on, the TCS, DSC or the brake assist system may have a malfunction and they may not operate correctly. Take your vehicle to an Authorized Mazda Dealer. In addition to the indicator light flashing, a slight lugging sound will come from the engine. This indicates that the TCS/DSC is operating properly.

You need the dealership or an auto electrician with a pro grade scan tool computer to check the live data and record it as you are driving.

There is a UFO flying near you.
wait until it passes, if your car still doesn\'t work, call the FBI.

you have a short circuit somewhere and I think an auto electrician would be the best bet.

The DSC light stands for Dynamic Skid Control or in lawmen's terms Traction Control. If the light stays on you have a problem with this system. You will need to have it diagnosed by someone who has the tools and expertise to find the problem. More than likely you are going to have to take it to a Jaguar dealer.

The first thing you need to look for is a light that isn't shutting off. Could be your interior light, a trunk light, glove box, tail light etc. If no lights, could be your starter solenoid is not shutting off. Try disconnecting the battery while you are at work, and see if it starts after. ( if you can't find any lights that stay on)

this indicates thatone of your wheel speed sensor is faulty. when you start up and the light stays on the system does a check and if one sensor does not respond the light will stay on deactivating the system.if the light goes of and comes on when driving the car can have the incorrect wheel size or the bearing gear can be defectivve

When the DSC Dynamic Stability Control light is ON your traction control is OFF. It will sometimes trigger the ABS light and the Rev Limiter it is an engine protection FAIL SAFE mode.
Check your brake switch on the brake pedal, this sounds like the problem wen replaced it will reset the Rev limiter, if the ABS light comes Check the wheel sensors

car is sensing a problem with the stability control system (DSC) or the antilock brake system (ABS). usually an ABS problem will turn off the DSC, so DSC may be ok, just ABS needs a look at.

since its an '08 model, it should still be covered by the BMW warranty provided you live in the USA. take it in and have them fix it. not safe driving with both systems deactivated.

DSC is your dynamic stability control, you probably went over something really hard and caused a fault, this is a normal response. If the fault stays on disconnect the battery and leave for five mins then reconnect, if you still have the same robelem your DSC module is faulty, it is located on the rear axel it is a block with an arm connected to the axel mid way on the axel.
Has nothing to do with yor abs the juddering was probably you driving over something which triggered the fault.
hope this helps
