What is a Jaguar X-Type X400 airbag control unit?

The Jaguar X-Type X400 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. A repair of the Jaguar X-Type X400 airbag control unit is often possible to restore full functionality.

This essential module, also known as SRS (Supplemental Restraint System) or RCM (Restraint Control Module), coordinates the deployment of airbags and seat belt pretensioners.

It is specially designed for the Jaguar X-Type (X400) model years 2001 to 2009 and ensures maximum occupant safety.

Why is the Jaguar X-Type X400 airbag control unit defective?

A defect in the Jaguar X-Type X400 airbag control unit often occurs due to internal errors, overvoltage, or after an accident, as it stores crash data. Repair is essential because a damaged module will not control the airbag systems correctly, thus severely compromising vehicle safety.

The module often blocks after a crash because the crash data memory is full and prevents the airbags from being deployed again.

This requires a special reset or replacement of the control unit to restore functionality.

Internal component failures or configuration problems can also lead to failure, which is typically indicated by a permanently illuminated airbag warning light.

Such a failure affects the entire safety electronics of the vehicle, which is why timely diagnosis and repair is essential.

Common error codes for Jaguar X-Type X400 airbag control unit repair

When repairing the Jaguar X-Type X400 airbag control unit, specific error codes may occur that indicate direct problems with the module, not with sensors. These codes are crucial for an accurate diagnosis, as they indicate a full crash data log, internal module errors, or configuration issues.

  • 13 → Crash data memory full → The control unit cannot store any more data and requires a reset.
  • 24 → RCM (control unit) internal error → There is an internal malfunction or defect in the control unit itself.
  • 54 → RCM configuration error → There are problems with the software configuration, often after replacing or updating the module.

These flash codes are the primary diagnostic tools for Jaguar X-Type X400 airbag systems and are reported directly by the control unit.

They are listed in official service documents and enable targeted Jaguar X-Type X400 airbag control unit repair.

What part numbers are available for the Jaguar X-Type X400 airbag control unit repair?

For a successful repair of the Jaguar X-Type X400 airbag control unit, exact OEM part numbers are crucial. The primary validated numbers, 1X4A14B321CF and 1X4A-14B321-CG, ensure compatibility for models from 2001 to 2009 and ensure the correct function of the safety module.

The most commonly used and reliably validated OEM part numbers for the Jaguar X-Type X400 airbag control unit are:

  • 1X4A14B321CF (Jaguar Original)
  • 1X4A-14B321-CG (Jaguar Original)

These part numbers are specifically assigned to the Jaguar X-Type X400 (2001–2009) and are listed in several professional databases.

The part number 4X4314B321BD may also be a possibility, but is not explicitly listed for the X-Type X400 in all sources.

A careful compatibility check based on the model year and series is essential for this part number to ensure a successful Jaguar X-Type X400 airbag control unit repair.

Supplier part numbers from manufacturers such as Bosch, Continental or Siemens are not directly listed as separate OEM numbers for this control unit in the available catalogs.

Typically, these modules carry the specific Jaguar OEM number directly on the component itself.
