What is a Hyundai i10 PA airbag control unit?
The Hyundai i10 PA airbag control unit is your vehicle's central safety unit, precisely controlling all occupant restraint systems, such as airbags and seatbelt pretensioners, in the event of an accident. It continuously monitors sensors and stores relevant crash data, ensuring proper function and safety throughout the entire airbag system.
This critical module is responsible for activating the airbags in the event of a collision. It ensures that the protection systems are triggered at the right moment to protect the occupants.
A functioning airbag control unit is essential for the active and passive safety of the Hyundai i10 PA. It ensures that the warning light is not illuminated and the system is operational.
Why is the Hyundai i10 PA airbag control unit defective?
The Hyundai i10 PA airbag control unit often fails because irreversible crash data is stored after an accident, requiring reprogramming. Internal errors caused by aging or voltage spikes can also cause failures, causing the airbag warning light to illuminate continuously and making repairs inevitable.
Because an impact saves crash data, the control unit cannot be used further without being reset. The airbag warning light then remains permanently illuminated.
Internal circuit problems or low voltage can also lead to failure. These system errors prevent the safety systems from functioning properly.
Defective connectors or corrosion can also disrupt communication. This often leads to diagnostic difficulties or an error message in the system.
Common error codes for Hyundai i10 PA airbag control unit repair
During Hyundai i10 PA airbag control unit repair, specific error codes occur that indicate internal module issues, not external sensors. These codes typically indicate power supply issues or internal hardware failures that require specific diagnostics to resolve the defect.
- B1101: Voltage/Power Supply Too Low → The airbag ECU receives insufficient supply voltage.
- B1102: Voltage/Power Supply Too Low → A critically low voltage was detected in the airbag control unit.
- B1112: Low battery voltage (discontinuous) → The control unit repeatedly registered too low vehicle electrical system voltage.
- B1620: SRSCM (Airbag Control Module) Internal Error (Continuous) → A serious internal defect exists in the airbag control module.
What part numbers are available for the Hyundai i10 PA airbag control unit repair?
For Hyundai i10 PA airbag control unit repairs, several verified Hyundai OEM part numbers are relevant. These numbers match the exact series and ensure compatibility. These numbers guarantee that the replacement or repair part perfectly matches your vehicle model and ensures safety.

- 95910-0X150: This OEM number also fits exactly the Hyundai i10 PA and is used for SRS module reset services.
- 95910-0X200: Another verified Hyundai genuine part number for the airbag control unit of the i10 PA.
These numbers are crucial for identifying the correct module for your vehicle. They ensure that the replaced or repaired part is fully compatible.
Technical specifications of the Hyundai i10 PA airbag control unit
The Hyundai i10 PA airbag control unit operates at a voltage of 10 to 15 volts and is tuned to the 12 V vehicle electrical system. It is designed for front-wheel drive models with gasoline engines and is typically protected with a 40 amp fuse to ensure its function in the safety system.
The system requires a stable DC voltage of 10-15 volts, typically from the vehicle's 12V electrical system.
The control unit is specifically designed for Hyundai i10 PA models with front-wheel drive and gasoline engines. It is compatible with engine variants ranging from 1.1 liters to 1.2 liters, producing between 63 hp (46 kW) and 79 hp (58 kW).
The airbag system is protected by a 40-ampere fuse in the vehicle, which underlines the high relevance of this safety system.
Diagnosis is performed via the OBD2 interface, with pin 12 often used for accessing the airbag module. Professional diagnosis requires a special device, as standard OBD2 scanners usually cannot read the module.
Compatibility: Hyundai i10 PA airbag control unit models and years
The airbag control unit is primarily designed for Hyundai i10 models of the first generation, PA series, built from approximately 2007 to 2018. It is compatible with various 1.1 and 1.2 liter petrol engine variants of these hatchback models and fits front-wheel drive vehicles.
The control unit is specifically designed for the first generation Hyundai i10 PA hatchback (PA series).
It covers models from approximately 2007 to 2018 and is designed for common gasoline engine variants.
Compatibility extends to models with 1.1 and 1.2 liter displacement and front-wheel drive.
Functionality and important features of the Hyundai i10 PA airbag control unit
The Hyundai i10 PA airbag control unit manages the entire airbag deployment process by processing signals from crash sensors and seatbelt pretensioners. After an accident, it stores important crash data and controls the deployment of the driver, front passenger, and side airbags to ensure optimal occupant protection.
The control unit is responsible for the precise control of airbag deployment. It processes sensor data to determine the correct moment of activation.
After an accident, specific crash data is stored in the module. This data is important for accident analysis and must be deleted before reuse.
It also monitors the status of the seat belt buckles and the passenger airbag switch, if equipped. Faults in these areas can trigger the airbag warning light.
The module supports advanced occupant protection functions, depending on the equipment variant of your Hyundai i10 PA.
Installation position and connections on the Hyundai i10 PA airbag control unit
The Hyundai i10 PA airbag control unit is typically located centrally in the vehicle, often under the seat or in the center console. It is electrically connected to the main vehicle electrical system and features robust connectors to crash sensors, seat belt pretensioners, and the OBD2 diagnostic port to ensure reliable operation.
The airbag control unit is usually installed centrally in the vehicle interior, allowing easy access for diagnostic and maintenance work.
It is connected to all relevant airbag components via robust connectors. These include crash sensors, seat belt tensioners, and the airbags themselves.
Power is supplied directly from the Hyundai i10 PA's 12V electrical system. A 40A fuse protects the system from overload.
For diagnostics, the control unit is accessible via the OBD2 interface. Pin 12 is often used for specific communication with the airbag module.
Special features and variants of the Hyundai i10 PA airbag control unit repair
Repairing the Hyundai i10 PA airbag control unit typically involves erasing stored crash data and restoring communication. Variants such as 95910-B9250 exist for various models, and recoding to the specific vehicle is essential after replacement or repair to ensure safety.
Common reasons for a necessary Hyundai i10 PA airbag control unit repair are crash data stored after an accident or communication problems caused by defective contacts.
Models like 95910-0X100 are common types that are frequently tested and reprogrammed if necessary. "Cloning" vehicle data to a replacement unit is often possible to transfer vehicle-specific data.
