What is a Ford Transit Mk7 airbag control unit?
The Ford Transit Mk7 airbag control unit is your vehicle's central safety unit, continuously monitoring sensor data and precisely deploying the airbags and seatbelt pretensioners in the event of a collision. It also stores important crash information for diagnostics and signals malfunctions to ensure the safety of the Ford Transit Mk7's occupants at all times.
This module, also known as the Restraint Control Module (RCM), is designed for Ford Transit Mk7 models from 2007 to 2013.
It continuously monitors the entire airbag system, including the sensors and ignition circuits, in order to react quickly and reliably if necessary.
Why is the Ford Transit Mk7 airbag control unit faulty?
A Ford Transit Mk7 airbag control unit is usually defective if it permanently stores crash data after an accident, requiring replacement or a professional reset. Other common causes of failure include internal electronic faults, short circuits, or moisture damage. These defects require immediate and professional Ford Transit Mk7 airbag control unit repair to ensure vehicle safety.
After an accident, the airbag control unit is often no longer functional because it cannot delete crash data once it has been stored.
Aging, internal component defects or external influences such as water ingress can also damage the electronics and cause the system to fail.
