What is a Jaguar XJR X350 airbag control unit?
The Jaguar XJR X350 airbag control unit is the central safety unit that activates all occupant restraint systems in the event of an accident. It precisely monitors a multitude of sensors, stores relevant crash data, and ensures the immediate and correct deployment of all airbag modules and seatbelt pretensioners in the vehicle to ensure maximum occupant safety.
This fully electronic module uses advanced multiplexing technology for fast and secure data communication. It processes signals from crash sensors, seat occupancy, and seatbelt status to respond precisely in an emergency.
In the event of a collision, the system records acceleration data and triggers passive safety systems as needed. At the same time, it stores important accident information that can be retrieved later for diagnostic purposes.
Why is the Jaguar XJR X350 airbag control unit defective?
A Jaguar XJR X350 airbag control unit can fail for a variety of reasons, commonly due to electronic malfunctions such as short circuits or overvoltage damage, but also due to environmental influences such as moisture. After an accident, the control unit is usually also marked as defective, as it stores crash data and requires a reset before further function can be ensured.
Common causes include internal component failures or disruptions in the vehicle's power supply. Aging processes in the electronics can also lead to failure over time, necessitating a Jaguar XJR X350 airbag control unit repair.
Another important point is the storage of crash data after an accident. This data blocks the control unit and must be professionally erased before the module can function again. A repair is often more cost-effective than a new part.
Common error codes for Jaguar XJR X350 airbag control unit repair
During a Jaguar XJR X350 airbag control unit repair, various error codes may occur that indicate specific problems with the airbag system. These codes are crucial for a precise diagnosis, although the exact Jaguar-specific error codes require a VIN query. However, typical generic codes are helpful in initial troubleshooting and locating the defect.
- B0010 → Driver Deployment Circuit Error → Problem in the driver airbag circuit, often caused by a broken wire or sensor malfunction.
- B0091 → Control Module Malfunction → A general error indicating internal problems in the airbag control module itself.
- B0020 → Side impact sensor malfunction → Defect or malfunction of a side impact sensor responsible for the side airbags.
- B0040 → Passenger Airbag Module Error → A malfunction or defect in the passenger airbag module or its wiring.
What part numbers are available for Jaguar XJR X350 airbag control unit repair?
There are various part numbers for the Jaguar XJR X350 airbag control unit repair, which can vary depending on the year of manufacture, equipment, and supplier. 100% identification is only possible by comparing the vehicle identification number (VIN) with official Jaguar catalogs such as JEPC or by checking the number directly on the control unit, as public lists often only provide exemplary information.
Well-known exemplary OEM numbers from Jaguar (Ford) include 3C2Q-14B056-AA and 3C2Q-14B056-AB. These are often found in professional databases such as TecDoc and are critical for accurate identification.
Suppliers such as Bosch and Autoliv also produce these control units and have their own numbers on the components. A typical example for Bosch is 0 265 700 013, while Autoliv may use numbers such as 901 032 000.
However, these details are only examples and serve as a first guide for Jaguar XJR X350 airbag control unit repairs. The number printed on the control unit's housing is often the most reliable source without a direct VIN query from a dealer or special diagnostic databases.
