What is a Jaguar F-Type S X152 airbag control unit?
The Jaguar F-Type S X152 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, which is essential for vehicle safety.
This module, also called the SRS Restraint Control Module (RCM), precisely coordinates the deployment of airbags and seatbelt pretensioners. It is crucial for protecting occupants in the event of a collision.
The control unit continuously monitors the vehicle's diverse sensors. This ensures that in the event of a collision, the safety systems can react within milliseconds to minimize injuries.
Why is the Jaguar F-Type S X152 airbag control unit defective?
A Jaguar F-Type S X152 airbag control unit is often considered defective because it stores specific crash data after an accident, preventing the restraint systems from reactivating without a reset. This is a safety measure that must be erased before recommissioning, or internal errors may be present.
After every collision, irreversible crash codes are stored in the control unit's memory. These disable the airbags and seatbelt pretensioners from functioning, even if the vehicle is otherwise undamaged.
In addition to crash codes, internal hardware defects or software problems can also affect the control unit. Such failures cause the airbag warning light to illuminate and the safety systems to be deactivated.
Common error codes for Jaguar F-Type S X152 airbag control unit repair
When repairing a Jaguar F-Type S X152 airbag control unit, specific error codes often occur, signaling internal problems with the module or its circuitry. These codes indicate that a reset or deeper diagnostics of the control unit is necessary to restore full functionality.
- 19 → Airbag circuit status fault – Driver → Error in the driver airbag circuit, reported directly by the airbag ECU.
- 21 → Airbag circuit status fault – Passenger → Malfunction in the passenger airbag circuit, also an ECU-related fault.
- 24 → RCM (Restraint Control Module) internal fault → Internal fault in the airbag control unit itself, often a hardware or software problem.
- 53 → Airbag audible warning circuit fault → Problem with the audible warning signal of the airbag system, monitored by the control unit.
- 54 → RCM configuration failure → Configuration error of the airbag control unit that prevents correct initialization.
These error codes primarily indicate problems that directly affect the control unit. They allow for targeted diagnosis and repair of the unit without suspecting sensors or belt tensioners as the cause.
For accurate reading and troubleshooting of these errors, a manufacturer-specific diagnostic tool is recommended. This ensures precise identification of the problem and professional repair.
What part numbers are available for the Jaguar F-Type S X152 airbag control unit repair?
Unfortunately, no specific OEM part numbers for the Jaguar F-Type S X152 airbag control unit could be identified in the provided search results. For accurate identification and to ensure compatibility, we recommend consulting official manufacturer catalogs or professional spare parts databases.
Searching for verified part numbers requires specialized research beyond the data we have available. This is crucial for finding the exact replacement or repair part.
Manufacturers such as Bosch, Continental, and Autoliv are often suppliers of airbag systems and may have the required part numbers in their own catalogs. TecDoc/TecAlliance databases are also valuable resources for this.
