What is a Hyundai Grand i10 BA airbag control unit?
The Hyundai Grand i10 BA 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.
This module processes signals from various sensors, including acceleration and impact sensors and seat occupancy detection.
It is crucial for the quick and precise deployment of the airbags and seatbelt pretensioners to ensure occupant safety in the Grand i10 BA.
In addition, the airbag control unit enables vehicle diagnostics via the OBD-II interface for system monitoring and fault analysis.
Why is the Hyundai Grand i10 BA airbag control unit defective?
A Hyundai Grand i10 BA airbag control unit often fails due to internal errors, voltage problems, or communication disruptions. Even after an accident, the control unit stores crash data that requires a reset, causing the airbag warning light to remain permanently illuminated.
Internal component failures can trigger error codes like B1620, which indicate a malfunction in the system.
Fluctuations in the vehicle electrical system voltage, whether undervoltage or overvoltage, can also cause specific error codes such as B1101 or B1102.
After an impact, the control unit irrevocably stores crash data, requiring a professional reset of the module or replacement for recovery.
Common error codes for Hyundai Grand i10 BA airbag control unit repair
When repairing the Hyundai Grand i10 BA airbag control unit, specific error codes often occur that indicate problems with the unit. In particular, these are communication errors like B1000 or driver airbag circuit problems like B1346, which require diagnosis and repair.
- B1000 → Control unit communication error → Problem with the signal processing or data exchange of the airbag control unit.
- B1346 → Driver airbag resistance too high → Indication of too high resistance in the squib circuit of the driver airbag, often directly at the control unit or in the wiring harness.
These error codes are typical for the airbag control unit of the Hyundai Grand i10 BA and directly indicate a malfunction in the ECU.
The B-codes mentioned are OBD-II compliant and primarily relate to the vehicle's body control system.
Crash data stored after a crash must be deleted by a specialist in order to restore the full functionality of the airbag system.
What part numbers are available for the Hyundai Grand i10 BA airbag control unit repair?
For repairing the Hyundai Grand i10 BA airbag control unit, the only confirmed and exact OEM part number is 95910-0X100 from Hyundai/Kia. This number is crucial for correctly identifying the specific module for this series.
Part number 95910-0X100 is the only one that has been verified multiple times for the airbag control unit of the Hyundai Grand i10 BA.
It is crucial to use this specific OEM number as other Hyundai airbag part numbers for different models or engine variants are not compatible.
Suppliers such as Bosch offer generic control units, but without publicly verified, specific serial numbers for the Hyundai Grand i10 BA.
The use of part numbers from other series or replacement numbers that do not exactly match is not permitted for a safe repair.
