DSC Sensor

The lateral-acceleration and yaw-rate sensors are combined in a single housing and designated the DSC sensor. The active front steering system is also provided with a second DSC sensor in addition to the DSC sensor fitted as standard.

DSC sensor 1 is located under the right front seat. DSC sensor 2 is located under the left front seat.

The two DSC sensors are technically identical but coded by means of the software so that they cannot be mixed up. DSC sensor 2 is used for redundant signal acquisition of yaw rate and lateral acceleration.

Both sensors supply yaw-rate and lateral acceleration signals. The use of two DSC sensors makes it possible to perform the plausibility check.
