What is a Jaguar Racing D-Type airbag control unit?
The Jaguar Racing D-Type 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, tailored to the demanding requirements of racing.
Although the historic D-Type originally lacked airbags, this specialized control unit represents modern safety systems for high-performance Jaguar vehicles. It acts as the brain of the passive safety system and is crucial for occupant protection.
The unit collects precise crash data from various acceleration and impact sensors. It makes decisions within milliseconds about whether to deploy airbags and seatbelt pretensioners to maximize safety in the event of a collision.
Why is the Jaguar Racing D-Type airbag control unit defective?
A Jaguar Racing D-Type airbag control unit fails because it stores crash data after an accident and then requires repair or replacement for safety reasons, or because internal electronic errors, software corruption, or communication problems occur that impair functionality. Such failures render the system inoperable.
Common causes include reaching the maximum storage capacity for crash events, which requires resetting or reprogramming the unit. Water damage or power surges can also cause irreversible damage to the sensitive internal circuits.
Internal component failures or software errors, such as configuration or version conflicts, prevent the control unit from initializing or functioning correctly. This can result in permanently illuminated airbag warning lights and requires professional diagnosis and repair of the Jaguar Racing D-Type airbag control unit.
Common error codes for Jaguar Racing D-Type airbag control unit repair
Common error codes during Jaguar Racing D-Type airbag control unit repair indicate internal control unit or configuration issues, such as full crash data logs, internal malfunctions, or communication errors. These codes, primarily from other Jaguar models such as the X-Type or S-Type, are crucial for diagnosing and repairing a faulty airbag control unit.
- 13 → Crash data memory full → The control unit has reached its maximum storage capacity after an accident.
- 19 → Driver airbag circuit fault → A problem in the driver airbag firing circuit, often internal to the control unit.
- 21 → Passenger airbag circuit fault → A fault in the passenger airbag ignition circuit, possibly in the control unit itself.
- 24 → RCM internal control unit error → A serious internal defect in the airbag control unit that requires repair.
- 53 → Airbag acoustic warning circuit fault → Malfunction in the circuit for the acoustic airbag warning signal.
- 54 → RCM configuration error → The control unit is incorrectly programmed or the configuration is corrupted.
- B1000 → Control unit communication error → Problems with data transmission between the airbag control unit and other systems.
- C1414 → Incorrect module design level (version error) → The software version of the control unit is not compatible with the vehicle.
What part numbers are available for Jaguar Racing D-Type airbag control unit repair?
The exact OEM part number for the Jaguar Racing D-Type airbag control unit for repair is not clearly identified in publicly available sources, as the D-Type was historically produced before airbag systems. However, specific numbers exist for comparable modern Jaguar models that aid in workshop diagnosis.
It's important to understand that airbag control units are VIN-specific. Therefore, repairing or replacing a defective control unit always requires exact part number compatibility to avoid malfunctions.
The OEM part numbers listed below refer to airbag control units for other Jaguar models, such as the XJR575, S-Type, or X-Type. To determine the correct part number for a specific Jaguar racing car, we strongly recommend contacting Jaguar or an authorized dealer directly.
Here are sample OEM part numbers for airbag control units on other Jaguar models that may be relevant for repairs in a workshop:
- C2D5633 → Manufacturer: Jaguar → For: Jaguar XJR575 (original part)
- 4R8314B321AC → Manufacturer: Jaguar / Autoliv → For: Jaguar S-Type (original part)
- 4X4314B321AF / 603449700 → Manufacturer: Jaguar / Bosch → For: Jaguar X-Type Diesel (Original / Supplier Part)
These numbers are for reference only, indicating the range of Jaguar airbag control units. A successful Jaguar Racing D-Type airbag control unit repair requires identifying the exact OEM number using the chassis number.
