Body sensor cluster stability sensor (BSC) is located under the right front seat. The sensor is supplied with 12 V and is grounded in Brake control module (BCM). Information from Body sensor cluster stability sensor (BSC) is used for stability calculations in Brake control module (BCM).

Body sensor cluster stability sensor (BSC) contains: 

• A yaw angle speed sensor that measures yaw angle speed in °/s.
• A lateral acceleration sensor that measures lateral acceleration in m/s² .
• An acceleration sensor that measures longitudinal acceleration. This sensor is available with different sensitivities depending on vehicle variant. A version is available for AWD, and another for (with higher sensitivity) is available for vehicles with transmission MPS6 that has the function HSA- Hill Start Assist.
• A roll angle sensor measures the roll angle speed in °/s. (only vehicles with roll control RSC).

The body sensor cluster stability sensor (BSC) communicates with the brake control module (BCM) via an internal CAN network.

The body sensor cluster stability sensor (BSC) can be diagnosed by the brake control module (BCM).

Upon replacement of the body sensor cluster stability sensor (BSC), the brake control module (BCM) must be calibrated following the information in VIDA (Volvo scan tool) vehicle communication or manually as determined by the test drive.
