This is a genuine OEM Adaptive Restraints Control Module (RCM) / Airbag ECU for the Jaguar S-Type fitted with the 4.2L V8 petrol engine. The module controls the Supplemental Restraint System (SRS), monitoring crash sensors, seat belt pretensioners, and airbag deployment systems to ensure proper occupant protection.


Manufactured to Jaguar factory specifications, this restraint control module ensures correct communication with the vehicle SRS network and OEM safety systems—ideal for replacing faulty, crash-locked, or water-damaged airbag ECUs.
