System Operation: DSD
WARNING: This page is about a different car, the 2015 Land Rover LR2, 2014 Land Rover LR2, and 2013 Land Rover LR2. However, it is still accessible from the selected car via links, so may be relevant.
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.
