Airbag control unit with part number 95910-GI110

What is the function of the airbag control unit 95910-GI110?

The airbag control unit with part number 95910-GI110 is the central control module for the Supplemental Restraint System (SRS) in the Hyundai Ioniq AE. It processes signals from acceleration sensors to precisely and promptly deploy the airbags and seatbelt pretensioners in the event of a crash, thereby ensuring occupant safety.

As the brain of the passive safety system, this control unit continuously monitors all connected components, including the crash sensors located at the front and sides of the vehicle, the seat occupancy detection system, as well as the ignition circuits for the airbags and seatbelt pretensioners.

In the event of a collision, the unit analyzes incoming sensor data within milliseconds and determines which restraint systems need to be activated. It is manufacturer-specifically designed for the safety architecture of the Hyundai Ioniq AE (2016–2019) and its facelift model (2019–2022).

Why does the control unit 95910-GI110 fail?

Defects in the 95910-GI110 control unit often arise from accidents that permanently store crash data in its memory. Other causes include electronic malfunctions due to water damage or failure of internal components, frequently indicated by error code B1620 (internal fault).

A major reason for repair is the storage of crash data after an accident. Even after a minor impact where the airbags did not deploy, the control unit may lock internally and require professional reset. This lock is a manufacturer‑imposed safety measure.

Electronic failures are also common. Moisture ingress can cause corrosion on the circuit board and lead to short circuits. Additionally, individual electronic components such as processors, memory chips, or capacitors may fail due to age or voltage spikes.

Error code B1620 specifically points to an internal, irreparable hardware fault within the control unit. This error cannot be cleared simply by erasing the fault memory and requires component‑level repair.

Similar control units with part numbers like 95910-G7400 or 95910-1Y110, installed in related Hyundai models, may exhibit comparable fault patterns.

How do you recognize a defect in the 95910-GI110?

A defective 95910-GI110 control unit typically manifests as a permanently illuminated airbag warning light on the instrument cluster. Additionally, the control unit may become unresponsive to diagnostic tools and fail to establish communication with the workshop tester.

The most obvious symptom is the persistently lit airbag check light (SRS light), which does not extinguish after starting the vehicle—indicating an active, safety‑critical fault in the restraint system.

Another clear sign is the lack of communication: when the workshop attempts to read the airbag system’s fault memory using a diagnostic tool, the connection fails, rendering the control unit inaccessible to external testers.

Workshop diagnostics reveal specific error codes pointing directly to the control unit itself, such as code B1620 for an internal hardware fault or entries explicitly referencing stored crash data.

In which models is the 95910-GI110 installed?

The airbag control unit 95910-GI110 is specifically designed for the first-generation Hyundai Ioniq. Airbag24’s repair services cover both pre‑facelift and facelift versions of this model series produced between 2016 and 2022.

At Airbag24, the 95910-GI110 control unit is repaired for the following specific vehicle models:

Hyundai Ioniq AE (model years 2016–2019)

Hyundai Ioniq AE Facelift (model years 2019–2022)

It is crucial to verify the exact part number, as this control unit is not compatible with other models, such as the newer Hyundai Ioniq 5 (NE). Compatibility is essential for the proper functioning of the safety system.

How is the 95910-GI110 professionally repaired?

Repair of the 95910-GI110 control unit at Airbag24 includes a professional diagnosis, elimination of the root cause—such as clearing crash data or replacing faulty components—and a final functional test. This restores the device to factory settings and ensures full operational readiness.

After the control unit has been expertly removed from the vehicle, a standardized repair process begins upon submission to Airbag24. First, an initial inspection verifies the customer-reported issues and reads out the fault memory.

The core of the repair lies in addressing the specific cause. For stored crash data, direct access is gained to the internal memory chip to safely erase it and unlock the unit. In the case of a hardware defect, indicated by error code B1620, the faulty electronic components on the circuit board are identified and professionally replaced.

Following restoration, each control unit undergoes a comprehensive functional test on a specialized test bench. Here, correct communication and the operation of all relevant circuits are simulated to ensure full operational readiness. We provide 2 years' statutory liability for defects on all repairs.
