What should I do?
Expert:  Matt replied 12 months ago.

Hello

DSC is the dynamic stability control so is most likely to be something to do with restricting wheel spin / skid by restricting power and or braking the wheel(s)

so the system has seen a fault and ideally the next step is to plug the car with with a scan tool to read off the code and point to the fault

However with ABS / DSC systems 99% of the time its a problem with one of the wheel speed sensors and I'd first check the connections at all four corners first for any signs of corrosion or chafed wiring.

The sensor is located in the wheel hub so you'll have to remove each wheel in turn to inspect them all.

Also check that the toothed wheel that the sensor points to is clean and free of any debris.

you can check each sensor's function by plugging the two output wires into an AC voltmeter and spinning the wheel quite quickly, you should get a voltage signal that increases with rev's.

Its possible that the fault is only a bad connection to one of the wheel sensors.

This may be remedied by removing each wheel in turn and unplugging each sensor and cleaning the contacts with a squirt of electrical contact cleaner. Then refitting.
