What is a Bentley Bentayga Hybrid Mk2 airbag control unit?
The Bentley Bentayga Hybrid Mk2 airbag control unit is the central safety unit that promptly activates all occupant restraint systems, such as airbags and seatbelt pretensioners, in the event of an accident. It continuously monitors sensors, stores important crash data, and ensures the proper functioning of all components of the vehicle's Supplemental Restraint System (SRS).
This sophisticated module, often installed under the passenger seat or in the center console, is critical to occupant safety. It communicates with other vehicle systems via the CAN bus to enable precise response to impact events.
Why is the Bentley Bentayga Hybrid Mk2 airbag control unit faulty?
The Bentley Bentayga Hybrid Mk2 airbag control unit can fail for a variety of reasons, commonly due to internal malfunctions, power surges, or crash data storage after an accident. These fault conditions compromise the vehicle's safety features, necessitating immediate Bentley Bentayga Hybrid Mk2 airbag control unit repair.
A defect is often indicated by an illuminated airbag warning light in the dashboard, even if no obvious accident has occurred. Internal memory corruption or software problems are also common causes of failure.
After a crash, the control unit stores data that requires replacement or a professional reset, otherwise it will not allow further deployment. A comprehensive diagnosis is essential to identify the exact cause and initiate the correct airbag control unit repair.
Common error codes for Bentley Bentayga Hybrid Mk2 airbag control unit repair
During Bentley Bentayga Hybrid Mk2 airbag control unit repairs, specific error codes often occur, indicating internal problems with the control unit or communication disruptions. These codes are crucial for a precise diagnosis and help the workshop fix the defect specifically.
Reading these error codes with a suitable diagnostic system is the first step in troubleshooting. Correct interpretation makes it possible to distinguish between an ECU error, a sensor problem, or another failure.
- B1000 → Control unit communication error → Internal or external communication problem of the airbag module.
- B1014 → Airbag control unit communication error → The airbag module cannot communicate with other systems.
- B1015 → Airbag control module error → Internal defect or malfunction within the control module itself.
- B1139 → Error within the SRS (Supplemental Restraint System) module → General internal defect of the supplemental restraint system.
- B1193 → Error related to the airbag control unit → Malfunction or inconsistency in the operation of the control unit.
- B1206 → Airbag RCM (Restraint Control Module) Error → Malfunction in the restraint system control module, usually another term for the airbag control unit.
- B1231 → Event Threshold Exceeded → The control unit has registered an event trigger that requires a reset.
- B1239 → Airbag Diagnostic Sensor Unit Malfunction → Problem with the control unit's internal diagnostic sensors.
- B1499 → SRS-ECU detects deployed airbag → The control unit is locked after an accident and must be reset.
- B1620 → Internal Error – SRS Control Unit Replacement Recommended → Serious internal error that often requires replacement or professional repair of the unit.
- 65535 → Intermittent error in the internal memory of the control unit → Transient or persistent problems with the internal memory of the airbag module.
What part numbers are available for the Bentley Bentayga Hybrid Mk2 airbag control unit repair?
Unfortunately, no exact, verified OEM part numbers (including supplier numbers from Bosch, Continental, Siemens, and Autoliv) are directly available for the Bentley Bentayga Hybrid Mk2 airbag control unit repair in publicly accessible sources. Reliable identification requires specific queries from your Bentley dealer or professional databases to avoid incorrect orders.
Determining the correct part number is crucial to ensuring the replacement part's compatibility with your Bentley Bentayga Hybrid Mk2. Generic or other airbag component numbers cannot be used for the control unit.
To accurately determine the part number, we recommend obtaining your vehicle's vehicle identification number (VIN) from an authorized Bentley dealer or accessing professional parts catalogs such as TecDoc/TecAlliance. This is the only way to find the correct unit for your Bentley Bentayga Hybrid Mk2 airbag control unit repair.
