What is a Hyundai Azera HG airbag control unit?
The Hyundai Azera HG airbag control unit is the central safety unit that activates all occupant restraint systems in the event of an accident. It continuously monitors sensors, stores critical crash data, and ensures the proper deployment of all airbag modules and seatbelt pretensioners to maximize occupant safety.
This SRS (Supplemental Restraint System) module is the brain of the airbag system. It continuously receives signals from various sensors in the vehicle.
In the event of an impact, the control unit evaluates the sensor signals and, if necessary, quickly triggers the airbags and belt tensioners.
Why is the Hyundai Azera HG airbag control unit defective?
The Hyundai Azera HG airbag control unit often malfunctions because it stores crash data after an impact, preventing it from continuing to operate without a reset. Internal hardware errors, power supply problems, or software corruption can also cause failure, requiring professional repair or replacement.
A common reason is the storage of crash data after an accident, which locks the system.
Aging, moisture damage or overvoltage can also damage internal components such as the microcontroller or memory module.
Common error codes for Hyundai Azera HG airbag control unit repair
During Hyundai Azera HG airbag control unit repairs, specific error codes may occur, indicating internal defects, communication problems, or stored crash data in the control unit. These codes are crucial for diagnosing the exact cause of the malfunction and initiating a targeted repair.
- B1000 → Control unit communication error → Data transmission failure between modules.
- B1230 → Control unit power supply error → Insufficient or unstable voltage supply to the module.
- B1240 → Control unit memory/software error → Corruption in the internal memory or software of the airbag module.
- B1620 → Crash data stored in the control unit → Accident events were recorded in the module and block the function.
- B1950 → Airbag control unit diagnostic error → The control unit cannot correctly check its own internal functions.
- B1993 → Control unit not initialized → Module was not set up or reset correctly for the vehicle.
What part numbers are available for the Hyundai Azera HG airbag control unit repair?
For the Hyundai Azera HG airbag control unit repair, the OEM part numbers 95910-3L000 and 95910-3L010 are primarily relevant, often supplemented by the Bosch supplier number 0 285 001 818. An exact match of the part number is essential for the compatibility and safe function of the system after the repair.
The Hyundai part number 95910-3L000 is widely used and corresponds to the Bosch number 0 285 001 818.
Another confirmed OEM number for the Hyundai Azera airbag control module is 95910-3L010, specifically for the 2009 model year.
It is crucial that the VIN coding of the original control unit is matched with the repair module to ensure full functionality.
What does the Hyundai Azera HG airbag control unit repair include?
Hyundai Azera HG airbag control unit repair involves professionally erasing crash data and correcting internal errors. The goal is to restore full functionality, often through reprogramming. This allows the airbag system to be safely restarted without having to replace the entire module.
After an accident, specialists delete the stored crash data that would prevent the system from being activated.
Internal hardware defects or software errors indicated by codes such as B1230 or B1240 will be resolved.
After the repair, a so-called "variant coding" is often necessary to perfectly adapt the module to the specific equipment of the Hyundai Azera.
Repaired modules usually come with a warranty that underlines their reliability for future function.
