System Operation: DSD

The DSD mode is used if the ABS module cannot operate the brakes or achieve a minimum deceleration rate, and the EPB module has no valid wheel speed signals. In the DSD mode, the EPB module uses the G sensor to monitor deceleration. To maintain vehicle stability, the EPB module initially applies a low clamp load to the brakes. When the G sensor signal indicates the vehicle has stopped, the EPB module fully applies the parking brake.
