What is a Jaguar XK X100 airbag control unit?
The Jaguar XK X100 airbag control unit is the central safety unit that activates all occupant restraint systems, such as airbags and seatbelt pretensioners, in the event of an accident. It continuously monitors the sensors, stores important crash data, and ensures the proper functioning of all airbag modules for your safety.
This module, also called the Airbag Control Module (ACM) or Airbag ECU, is the brain of the Supplemental Restraint System (SRS) in your vehicle.
It continuously processes signals from various crash sensors and makes lightning-fast decisions about triggering the safety systems.
Why is the Jaguar XK X100 airbag control unit defective?
The Jaguar XK X100 airbag control unit can fail for a variety of reasons, often after an accident due to stored crash data or due to age-related internal component failures. Because the control unit is a highly sensitive electronic component, corrosion, moisture, or overvoltage can also impair its function, making a Jaguar XK X100 airbag control unit repair unavoidable.
After an impact, the control unit stores indelible crash data that prevents the airbag system from continuing to function.
Internal electronic defects, such as cold solder joints or worn components, can also lead to failure and activate the airbag warning light.
Common error codes for Jaguar XK X100 airbag control unit repair
While no specific Jaguar trouble codes are publicly listed exclusively for part number C2P24640, generic B-codes are often encountered during Jaguar XK X100 airbag control unit repairs. These codes indicate internal problems or communication errors and require specialized vehicle diagnostics.
- B1000 → Control unit communication error → Signal disturbance between airbag ECU and other systems
- B1216 → Airbag Sensor Signal Error → Defective or implausible signals from a crash sensor
- B1239 → Control unit internal error → Internal malfunction or miscalculation in the airbag control unit
- B1240 → Airbag Deployment Circuit Fault → Problem with the deployment circuit of an airbag or seat belt pretensioner
What part numbers are available for Jaguar XK X100 airbag control unit repair?
For Jaguar XK X100 airbag control module repair, the only verified OEM part number is C2P24640, although C2P16589 exists as an alternative or previous number. This genuine Jaguar part number is specifically validated for the X100 series, including the XKR 5.0L V8 A/T, and ensures correct module identification.
These numbers refer exclusively to the central airbag control unit, not to individual sensors or instrument panel airbags.
There are no officially listed supplier part numbers such as Bosch, Continental or Siemens for this specific control unit in the Jaguar XK X100.
Important technical details for your Jaguar XK X100 airbag control unit repair
Jaguar XK X100 airbag control unit repair is relevant for 1997 to 2006 models with 4.0- and 4.2-liter V8 engines, as the control unit is central to occupant safety. It often needs to be reset or repaired after an accident or in the event of internal failures, rather than completely replacing it, which is more cost-effective.
The module is usually installed under the dashboard or in the center console and requires careful work to access.
It is networked with all airbag modules, seat belt pretensioners and crash sensors to ensure comprehensive system monitoring.
Specialized repair services can erase the crash data stored in the module or repair internal defects to restore the control unit to full functionality.
