What is the restraint control module?

The Restraint Control Module (RCM) is a critical component in a vehicle's safety system, responsible for monitoring and controlling the deployment of airbags and seatbelt pretensioners during a collision. It processes data from various sensors to determine the severity of an impact and activates the appropriate safety measures to protect occupants. The RCM also performs self-diagnostics to ensure the proper functioning of the airbag system and may store crash data for analysis after an incident.
