What is a Jaguar E-Type Series II airbag control unit?
The Jaguar E-Type Series II Airbag Control Unit is an aftermarket safety unit that coordinates the deployment of airbags in the event of a crash in classic cars such as the E-Type Series II (1968-1971). Since this model did not have airbags from the factory, it is a specialized solution for restored or modified vehicles. It monitors sensors, stores crash data, and ensures the functionality of all airbag modules in the vehicle.
It acts as the central control unit for an aftermarket airbag system tuned to the vehicle's 12-volt electrical architecture. This module processes signals from acceleration sensors and controls the deployment of the airbags to protect the occupants in the event of a collision.
Such systems are typically installed during restorations to integrate modern safety standards into historic vehicles. Proper function requires precise adaptation to the individual vehicle and the airbag components used.
Why is the Jaguar E-Type Series II airbag control unit defective?
A defective airbag control unit in a Jaguar E-Type Series II, which was installed as an aftermarket solution, can have various causes, from internal electronic errors to voltage spikes in the vehicle's electrical system to crash data stored after an accident. These problems lead to the safety system no longer functioning properly or the airbag warning light remaining permanently illuminated, making repair unavoidable.
Errors often result from crash data stored in the module after an accident, which requires a reset. Age-related wear and tear or corrosion on the connectors can also impair the function of the control unit.
An internal memory error or communication problems with other sensors and actuators in the airbag system can also cause the control unit to be diagnosed as "defective." Repairing the control unit resolves these issues and restores full functionality.
Common error codes for Jaguar E-Type Series II airbag control unit repair
There are no original airbag control units or specific trouble codes for the Jaguar E-Type Series II, as this model was delivered without airbags from the factory. However, aftermarket systems may display generic OBD-II B codes or typical Jaguar-specific airbag trouble codes (common on newer models like the X-Type), indicating control unit issues.
- B0190 → Airbag control unit communication error → Malfunction in the data transmission to the airbag ECU.
- B0240 → Airbag control unit internal memory error → Problem with the internal memory of the airbag module.
- B1000 → Control unit communication error → General communication fault in the airbag system.
- 19 → Airbag circuit status error – Driver → Problem in the driver airbag circuit (e.g. X-Type).
- 21 → Airbag circuit status error – passenger → Problem in the passenger airbag circuit (e.g. X-Type).
- 24 → RCM (Restraints Control Module) internal error → Internal defect in the airbag control unit.
- 53 → Airbag acoustic warning circuit error → Error in the warning function of the airbag system.
- 54 → RCM configuration error → Incorrect configuration of the airbag control unit.
What part numbers are available for Jaguar E-Type Series II airbag control unit repair?
There are no 100% verified OEM part numbers for the Jaguar E-Type Series II airbag control unit, as this vehicle model was manufactured without airbags at the factory. If airbag systems were retrofitted, the control units and their part numbers most likely originate from universal aftermarket kits or third-party suppliers, making a clear assignment of OEM numbers impossible.
The original Jaguar parts catalogs for the E-Type Series II do not list airbag control units, as this technology was not standard equipment at the time of production (1968-1971). Therefore, there are no specific original equipment manufacturer (OEM) part numbers for this vehicle model.
For retrofitted systems, repair service providers typically work with the part numbers found on the installed retrofit module itself. These numbers vary greatly depending on the manufacturer of the retrofit kit and are not standardized like OEM part numbers.
