What is a Jaguar XFR X250 airbag control unit?
The Jaguar XFR X250 airbag control unit, also known as the Restraint Control Module (RCM), is the central component of your vehicle's passive safety system. It is responsible for processing impact data, deploying the airbags and seatbelt pretensioners as appropriate in the event of an accident, and monitoring system integrity to ensure your safety.
This genuine Jaguar part is specifically designed for the XFR X250 platform, which was typically produced between 2008 and 2014.
It continuously monitors various sensors in the vehicle to precisely determine the impact force and direction and initiate appropriate protective measures.
Why is the Jaguar XFR X250 airbag control unit defective?
A Jaguar XFR X250 airbag control unit can fail because it permanently stores crash data after an accident, preventing it from being deployed again. Internal malfunctions such as hardware defects, voltage fluctuations, loose fasteners, or corrupted configuration data can also lead to failure, necessitating a professional Jaguar XFR X250 airbag control unit repair.
Common causes of failure include ground point problems or age-related wear of the RCM's internal components.
In many cases, the control unit is not completely "broken," but merely blocked by stored crash data that requires a reset.
This causes the airbag warning light to stay on and the system to no longer be operational.
Common error codes for Jaguar XFR X250 airbag control unit repair
During a Jaguar XFR X250 airbag control unit repair, specific error codes are often read out, indicating internal problems with the control unit. These codes are crucial for diagnosis and indicate whether a crash data reset, reprogramming, or a repair of the module is necessary to restore full functionality.
- 12 (B1342) → Internal error in the airbag control module (RCM) → Possible causes are loose fasteners, voltage problems or a defect in the control module itself.
- 24 → RCM internal errors → Often after accidents or hardware defects in the airbag control unit; causes the warning light to illuminate.
- 54 → RCM configuration error → Occurs, for example, after incorrect programming or if the control unit memory is damaged.
- 13 → Crash data stored in the control unit → The module contains crash information and must be reset or repaired to be usable again.
These codes are exclusively ECU related and usually require specialized diagnosis and professional Jaguar XFR X250 airbag control unit repair.
A high-quality airbag OBD scanner is essential for correctly reading and clearing these B-codes.
