1.DSC switch

The DSC system is active whenever the ignition is switched on. When pressed, the switch provides a momentary 12 volt signal to the ABS ECU to switch the off the DSC function (DSC indicator in cluster illuminated.) When pressed again, the DSC function switches back on (DSC Indicator in cluster goes off.)

The DSC function can determine if the vehicle is close to roll over and will cut engine torque to ensure that vehicle speed does not increase, thus reducing the chance of vehicle rolling over.

If the DSC function fails, the air suspension drops to between standard and motorway height, to provide increased stability.
