DSC Button

The DSC button is located on the SZM however the SZM provides no processing, it is simply a housing for the button which is a hardwired input to the DSC control unit.

The function of the button is different than for 2wd vehicles. Brake intervention remains active for the ADB function after pressing the button to turn off the DSC. 

Only ASC engine intervention and DSC yaw intervention are deactivated. 

The DSC warning lamp will be illuminated to remind the driver that these functions have been disabled. Pressing the button again returns the system to normal status.
