Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Body Sensor Cluster Stability Sensor (BSC) (DSTC Only)
The body sensor cluster stability sensor (BSC) is under the right-hand front seat. The sensor is supplied with 12 V and is grounded in the brake control module (BCM). The information from the body sensor cluster stability sensor (BSC) is used for stability calculations in the brake control module (BCM). The body sensor cluster stability sensor (BSC) contains a yaw angle sensor which measures the yaw angle speed in °/s, and a lateral acceleration sensor which measures lateral acceleration in m/s2 . The body sensor cluster stability sensor (BSC) for AWD also contains an acceleration sensor which measures longitudinal acceleration
The body sensor cluster stability sensor (BSC) communicates with the brake control module (BCM) via an internal controller area network (CAN).
The body sensor cluster stability sensor (BSC) can be diagnosed by the brake control module (BCM).
When replacing the body sensor cluster stability sensor (BSC), the brake control module (BCM) must be calibrated using VIDA (Volvo scan tool) or manually according to the test drive.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
