What is a Hyundai i30 FD airbag control unit?
The Hyundai i30 FD airbag control unit is the central safety unit that activates all occupant restraint systems, such as airbags and seatbelt pretensioners, in the event of an accident. It precisely monitors sensor data, stores important crash information, and ensures the proper functioning of all airbag modules in the vehicle to provide maximum safety.
As a key electronic component, the control unit processes signals from impact sensors. It decides within milliseconds whether the airbags need to be deployed.
It is connected to various sensors and airbags via specific, often yellow, airbag connectors. These connectors have two to three gold pins for precise data transmission and corrosion resistance.
Why is the Hyundai i30 FD airbag control unit defective or needs repair?
A Hyundai i30 FD airbag control unit is often defective or requires repair because it irreversibly stores crash data after an accident or has internal errors. A failure or malfunction can also be indicated by illuminated airbag warning lights or specific error codes, making professional diagnosis and repair essential.
After an accident, the control unit stores indelible crash data, which requires a Hyundai i30 FD airbag control unit repair or replacement, otherwise the unit remains locked.
Internal hardware or software errors can also cause the control unit to malfunction. These often manifest as communication problems or system errors.
Reprogramming is also necessary due to recalls where the software was faulty and could lead to uncontrolled activations. This is a case that also requires a repair or update of the control unit.
Common error codes for Hyundai i30 FD airbag control unit repair
During a Hyundai i30 FD airbag control unit repair, specific error codes (B-codes) often occur, which directly indicate problems with the airbag control unit itself. These codes signal internal defects, communication problems, or crash data storage, necessitating targeted diagnosis and repair.
- B1000 → Control unit communication error → The airbag control unit has a fault in the data transmission.
- B1015 → Faulty Airbag Control Module → An internal fault in the airbag control module has been diagnosed.
- B1139 → Error within the SRS control unit → The entire occupant restraint system (SRS) reports an error in the control unit.
- B1193 → Airbag module related error (control unit) → There is a problem in the airbag module that can be attributed to the control unit.
- B1206 → Airbag RCM (Restraint Control Module) Error → The Restraint Control Module, i.e. the control unit, is faulty.
- B1342 → SRS (Supplemental Restraint System) Error → A general system error of the SRS control unit has been detected.
- B1346 → Driver side airbag resistance too high (1st stage) → There is too high resistance in the driver deployment circuit, often a sign of a control unit or wiring defect.
- B1620 → SRS Error → Another generic SRS system error that points to the control module.
- B1649 → Crash detected (control unit) → The control unit has registered an accident and is no longer functional after a crash.
What part numbers are available for the Hyundai i30 FD airbag control unit repair?
For Hyundai i30 FD airbag control unit repairs, two verified OEM part numbers are primarily relevant: 95910-2L030 and 95910-R000 or 959102R000. These numbers identify the original Hyundai part and are crucial for correctly diagnosing and replacing the control unit in the event of a failure.
- 95910-2L030
- 95910-R000 / 959102R000
These OEM numbers are recorded multiple times in various databases and are considered the main numbers for the airbag control unit in the Hyundai i30 FD. The spelling may vary regionally or depending on the manufacturer, with or without hyphens, but they refer to the same part.
There are no publicly available OEM numbers from well-known suppliers such as Bosch or Continental. These are typically kept internally at Hyundai and are not separately cataloged, which limits the search for spare parts for a Hyundai i30 FD airbag control unit repair to Hyundai's own numbers.
Compatibility and installation position for the Hyundai i30 FD airbag control unit repair
The Hyundai i30 FD airbag control unit repair primarily affects models from 2007 to 2012, including the 5-door hatchback and station wagon (CW), as well as various engine variants. The control unit is typically located centrally in the center console or under the dashboard, which is crucial for efficient diagnosis and repair.
The control unit is compatible with the Hyundai i30 FD, both the 5-door and station wagon (CW) versions. It fits vehicles built from approximately 2007 to 2012.
This includes models with the 1.4 petrol engine and 1.6 CRDi diesel variants. Compatibility extends across various trim levels of this series.
The airbag control unit's installation location is strategically chosen: It is usually located near the center console or under the dashboard. This ensures a central position for rapid signal processing of all safety components.
The control unit is connected to the airbags and impact sensors via wiring harnesses with bright yellow airbag connectors. These special connectors feature a safety clip to prevent accidental activation during installation or repair of the Hyundai i30 FD airbag control unit.
The importance of Hyundai i30 FD airbag control unit repair after an accident
Repairing the Hyundai i30 FD airbag control unit after an accident is crucial, as the unit stores crash data and will no longer function without professional repair. A professional repair erases this data and restores the full functionality of the occupant protection system, which is essential for safety.
After an accident, irreversible crash data is stored in the control unit, requiring reinitialization by a specialized workshop. Simply deleting this data is not possible, underscoring the need for a comprehensive repair.
The repair of such a control unit usually takes 3-5 business days, during which the stored crash data is deleted and the device is made fully functional again.
Vehicles manufactured between May 3, 2007, and May 8, 2012 were affected by a recall. The control unit's software was reprogrammed to minimize safety risks such as uncontrolled activations, which also constitutes a form of repair.
Because this is a safety-critical component, the Hyundai i30 FD airbag control unit repair and replacement should only be performed by trained specialists. This ensures that the airbag system functions properly again after a failure and provides maximum safety.
