What is a Jaguar XF Sportbrake X250 airbag control unit?
The Jaguar XF Sportbrake X250 airbag control unit is the central safety unit in the vehicle, continuously monitoring the sensor system and deploying the occupant restraint systems, such as airbags and seatbelt pretensioners, precisely and instantly in the event of a collision. It also stores important crash and diagnostic data, which is essential for later fault analysis and Jaguar XF Sportbrake X250 airbag control unit repair.
This important component is located in the driver's compartment, usually protected under the center tunnel or a seat, to ensure optimal protection and functionality. It is crucial for the passive safety of all occupants.
The system works seamlessly with acceleration and impact sensors to detect the precise time and severity of an accident. Once triggered, it stores all relevant information for future diagnostics.
A functioning airbag control unit is therefore not just a component, but the brain of the entire occupant protection system in the Jaguar XF Sportbrake X250.
Why is the Jaguar XF Sportbrake X250 airbag control unit defective?
The Jaguar XF Sportbrake X250 airbag control unit may be defective because crash data is often stored after an accident, blocking the system and triggering a permanent error message; alternatively, an internal hardware or software error or a faulty configuration may lead to failure, requiring a Jaguar XF Sportbrake X250 airbag control unit repair.
The most common reason for a defective airbag control unit is the storage of crash data after a collision. This data signals to the vehicle that the system has been deployed and is now locked.
In addition to accidents, internal errors such as faulty circuits or memory problems can damage the control unit. Such problems often manifest themselves as an illuminated airbag warning light without any apparent external damage.
Configuration errors or incompatible software updates can also lead to control unit failure. In these cases, professional diagnosis and specialized repair are essential to restore full functionality.
Common error codes for Jaguar XF Sportbrake X250 airbag control unit repair
During Jaguar XF Sportbrake X250 airbag control unit repair, specific error codes often occur that signal internal problems, configuration errors, or the presence of stored crash data in the control unit itself and require targeted repair to restore the vehicle's safety functions.
- 24 → RCM (Restraint Control Module) internal error → Describes a problem within the hardware or software of the airbag control unit.
- 54 → RCM configuration error → Indicates incorrect or incomplete programming of the control unit.
- 13 → Crash data memory full → Indicates that event data is stored after an accident that needs to be deleted.
These error codes are manufacturer-specific for Jaguar and are read using a diagnostic tool. They help the workshop determine the exact cause of the malfunction and find an effective solution.
Code 13, in particular, often requires a reset of the control unit to clear the airbag warning light and allow the module to be reused. A professional repair is a cost-effective alternative to purchasing a new one.
What part numbers are available for the Jaguar XF Sportbrake X250 airbag control unit repair?
For Jaguar XF Sportbrake X250 airbag control unit repair, the primary OEM part number CX23-14D374-AD is the only official and verified reference; alternatively, the identifier DDJ8A is used, which, however, denotes identical hardware, while no separate supplier part numbers exist, which facilitates clear identification.
Part number CX23-14D374-AD is the correct OEM number for the airbag control unit in the Jaguar XF X250, including the Sportbrake model. It is valid for model years from approximately 2011 to 2015.
Although DDJ8A is often seen in retail stores, this identifier represents the same hardware as CX23-14D374-AD. When repairing or replacing a control unit, an exact match of the number is crucial for compatibility.
There are no standalone part numbers from suppliers such as Bosch or Continental listed explicitly for this Jaguar module. Therefore, the OEM number is the primary reference for successful repair or replacement part procurement.
