What is a Volvo S60 Series 2 airbag control unit?

The Volvo S60 Series 2 airbag control unit is the central safety unit for your vehicle, precisely activating all occupant restraint systems, such as airbags and seatbelt pretensioners, in the event of an accident. It continuously monitors sensors, stores relevant crash data, and ensures the proper functioning of the entire safety system.

This device, known as the Restraint Control Module (RCM), is essential for occupant safety. It collects signals from acceleration sensors and seatbelt pretensioners to trigger the necessary safety measures in the event of a collision.

As the heart of the Supplemental Restraint System (SRS), it not only controls the deployment but also the permanent monitoring of all airbag and belt tensioner components.
