What is a Hyundai Azera TG airbag control unit?
The Hyundai Azera TG 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 important crash data, and ensures the proper functioning of front and side airbags and seatbelt pretensioners. It is essential for your vehicle's safety.
This module, also called the SRS Airbag Computer Diagnostic Control Module, forms the heart of the occupant protection system. It is responsible for deciding whether to deploy the restraint systems in milliseconds.
Manufactured as an original Hyundai component, often by supplier Bosch, it meets the highest quality and safety standards. The correct functioning of this control unit is crucial for the vehicle's occupants.
Regular diagnostics can help identify potential problems early. If a failure occurs, a professional Hyundai Azera TG airbag control unit repair is essential.
Why is the Hyundai Azera TG airbag control unit defective?
The Hyundai Azera TG airbag control unit can become defective because it stores crash data after an accident, causing a permanent error (hard code) and activating the airbag warning light. Internal electronic errors, surges, or age-related component failure can also cause the control unit to fail, necessitating repair.
A common reason for failure is the storage of crash events. After an accident, the module records this data and locks itself to prevent unintentional reuse.
This causes the airbag warning light to remain permanently illuminated, even if there is no other visible damage to the system. Deleting this data requires specialized tools and expertise.
Other causes can include corrosion, water ingress, or a faulty power supply. Software errors or defective internal components can also render the control unit unusable.
In such cases, professional diagnosis and Hyundai Azera TG airbag control unit repair are essential. Attempts to fix the problem without expert knowledge may compromise safety.
Common error codes for Hyundai Azera TG airbag control unit repair
During Hyundai Azera TG airbag control unit repair, specific error codes may occur that indicate problems directly with the module or its primary wiring. Typical codes include B1000 for communication problems within the control unit and B1347 for low resistance in the driver airbag circuit, which require a precise diagnosis.
- B1000 → Control unit communication error → A malfunction in the internal or external data communication of the airbag control unit.
- B1347 → Driver airbag resistance too low (Level 1) → A problem with the resistance in the driver airbag circuit, often caused by the control module or its wiring.
These error codes are stored by the system and can be read with a suitable OBD diagnostic tool. They signal to the driver a malfunction in the safety system.
It's important to note that these codes are directly related to the airbag control unit. Other problems, such as sensor or seatbelt pretensioner defects, generate other specific codes.
Professionally clearing these error codes often requires resetting the module. Improper handling can impair the function of the airbag system.
What part numbers are available for the Hyundai Azera TG airbag control unit repair?
For Hyundai Azera TG airbag control unit repairs, specific OEM part numbers are crucial to ensure compatibility and safety. The original Hyundai part number is 959103L000, while the corresponding Bosch OEM number is 0 285 001 818. These are relevant for model years 2006-2008.
Part number 959103L000 is the official Hyundai OEM number for the airbag control unit in the Azera TG. This has been verified multiple times and is the primary reference for replacement parts.
As a supplier, Bosch frequently produces these modules, which can be identified by the number 0 285 001 818. Both numbers refer to the same component for the vehicle.
It is absolutely crucial to accurately match the part number before replacement. An incorrect part number can result in incompatibility and a continued airbag warning light.
These specific part numbers ensure that you receive the correct SRSCM (Supplemental Restraint System Control Module). This is the only way to restore full functionality to the safety system.
Please note that after installation, the module often needs to be programmed or coded to suit the vehicle's specific needs. This ensures that it communicates with the vehicle's serial number and functions correctly.
