What is a Bentley Continental GT Mk2 airbag control unit?
The Bentley Continental GT Mk2 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.
As a core component of the Supplemental Restraint System (SRS), it processes data from impact sensors at lightning speed.
It precisely controls the deployment of airbags and seat belt pretensioners to provide maximum protection to occupants and stores important accident data.
Why is the Bentley Continental GT Mk2 airbag control unit faulty?
Common causes of a faulty Bentley Continental GT Mk2 airbag control unit include electrical malfunctions, power surges, or previous accident damage, as crash data can lock the module. In these cases, a repair or reset is required to restore full safety system functionality and prevent failure.
A typical reason for failure is the storage of crash data after an impact, even in minor collisions.
Aging, corrosion due to moisture or internal electronic errors can also cause the module to break down and require professional workshop diagnosis.
Common error codes for Bentley Continental GT Mk2 airbag control unit repair
When diagnosing and repairing the Bentley Continental GT Mk2 airbag control unit, communication errors primarily occur, indicating a malfunction in the internal electronics or connection. These specific codes help a workshop specifically troubleshoot problems directly at the control unit.
- 01321 → Airbag control unit (J234) → no signal/communication (sporadic)
- B1000 → Control unit → Communication error
These error codes directly indicate a problem with the airbag control unit itself and require specific repair or replacement of the module.
Codes relating to sensors or other airbag components are explicitly excluded here, as they do not originate from the control unit itself.
What part numbers are available for the Bentley Continental GT Mk2 airbag control unit repair?
Several OEM part numbers are relevant for repairing the Bentley Continental GT Mk2 airbag control unit, including the original Bentley numbers 3W3 959 655 A and 3W7 909 601, as well as the Bosch supplier number 3D0 909 601 E. These numbers ensure correct compatibility and function of the system.
