What is a Jaguar XKR-S X150 airbag control unit?
The Jaguar XKR-S X150 airbag control unit is the central safety unit that activates all occupant restraint systems in the event of an accident. It monitors sensors, stores crash data, and ensures the proper functioning of all airbag modules in the vehicle to ensure maximum safety.
This essential module, often located in the center tunnel, processes signals from impact and acceleration sensors. In the event of an impact, it triggers the airbags and seatbelt pretensioners within milliseconds.
The control unit for the Jaguar XKR-S X150 (model years 2007 to 2014) is a complex system that continuously monitors the vehicle's safety functions.
Why is the Jaguar XKR-S X150 airbag control unit defective?
A Jaguar XKR-S X150 airbag control unit can fail for a variety of reasons, often after an accident due to stored crash data or due to electrical problems such as overvoltage. These defects prevent the safety system from functioning properly and require professional repair.
After an accident, airbag control units irreversibly store "crash data," making further use of the module impossible without professional reprogramming. This is the most common reason for a Jaguar XKR-S X150 airbag control unit repair.
Other reasons may include internal electronic faults, moisture damage, or voltage spikes in the vehicle electrical system, which can damage the control unit's sensitive circuits and cause failure.
Faulty sensors or belt tensioners can also indirectly affect the control unit by constantly producing error codes and impairing its function, making diagnosis essential.
Common error codes for Jaguar XKR-S X150 airbag control unit repair
Diagnosing a faulty Jaguar XKR-S X150 airbag control unit often begins with reading specific error codes that indicate internal problems or communication disruptions. These codes help pinpoint the cause of the failure and initiate repair.
- **B1000**: Control unit communication error → Meaning: The airbag control unit cannot communicate correctly with other systems → Cause: Internal fault of the control unit or bus error.
- **B0061-64**: Passenger belt pretensioner control unit error → Meaning: Problems with the control of the belt pretensioner on the passenger side → Cause: Error in the control unit, although it relates to the belt pretensioner.
- **B0072-1B**: Passenger belt pretensioner control unit error → Meaning: Specific error in the control of the passenger belt pretensioner → Cause: Internal error or cable problem of the airbag ECU.
- **B0028-1B**: Resistance too high passenger airbag control module → Meaning: Abnormally high resistance in the passenger airbag circuit → Cause: Internal component of the airbag module is faulty.
- **B100D96**: Steering column lock authorization low voltage → Meaning: The airbag control unit is receiving insufficient voltage signals from the steering column lock → Cause: Voltage supply problems affecting the airbag system.
- **B1C3494**: Steering column telescopic solenoid unexpected action → Meaning: Unexpected movements or malfunctions of the steering column solenoid → Cause: May indicate interference from the airbag control unit.
- **B1B0167**: Key transponder start control unit invalid response → Meaning: Communication error between key transponder and start control unit → Cause: Can indirectly affect the airbag control unit if it is connected to the communication bus.
- **U300055**: Stored vehicle configuration data is incorrect → Meaning: The configuration data in the airbag control unit is incorrect or damaged → Cause: Incorrect coding or software error.
- **U300049**: Instrument cluster internal error → Meaning: The instrument cluster reports an internal error → Cause: Can disrupt communication with the airbag control unit.
- **U015500**: Loss of communication with instrument cluster → Meaning: The airbag control unit cannot communicate with the instrument cluster → Cause: Bus error, wiring problem or internal failure of the control unit.
- **"Crash data full" (Code 13)**: Crash data saved → Meaning: The module has detected a collision and saved the crash data irreversibly → Cause: Repair required by resetting the crash data after an accident.
What part numbers are available for the Jaguar XKR-S X150 airbag control unit repair?
The specific OEM part number for the Jaguar XKR-S X150 airbag control unit is often difficult to identify, as much of the information is generic or refers to other airbag components. Direct research with the manufacturer or specialized databases is essential for an accurate Jaguar XKR-S X150 airbag control unit repair.
Although a generic part number such as C2P24640 exists for a Jaguar Air Bag Control Module, it is not specific to the XKR-S X150 model.
Part numbers such as C2Z17877AMT or C2Z17877LEG are known for the steering wheel airbag and not for the control unit itself.
Due to the lack of clear information, it is strongly recommended to consult official Jaguar manufacturer catalogs, professional spare parts databases (e.g. TecDoc) or direct suppliers such as Bosch, Continental or Siemens to find the exact part number for your Jaguar XKR-S X150 airbag control unit and ensure compatibility.
A professional workshop can use the vehicle identification number (VIN) to determine the correct part number for repairing or replacing the defective control unit.
