Airbag control unit with part number 95910-1C100

What is the function of Airbag Control Unit 95910-1C100?

The airbag control unit with part number 95910-1C100 is the central control module of the occupant safety system (SRS) in the Hyundai Getz TB. Its primary task is to process crash sensor data, enabling precise and rapid activation of restraint devices—such as front and side airbags, as well as seatbelt pretensioners—in the event of a collision.

As the “brain” of the safety system, it continuously monitors all connected components, including ignition circuits, sensors, and seatbelt pretensioners. At the same time, it logs critical fault information in its internal fault memory and permanently stores so‑called crash data upon impact—even if no airbags were deployed.

This unit is essential for passive vehicle safety. Proper functionality is crucial to ensure that all restraint system components are correctly activated in an emergency.

Why does Airbag Control Unit 95910-1C100 fail?

The most common causes of failure for control unit 95910-1C100 are stored crash data following an accident and internal electronic malfunctions. Often, a fault in the internal memory or driver ICs leads to complete failure, indicated by a lit airbag warning light and persistent error codes that cannot be cleared.

A primary reason for repair is the presence of crash data stored in the internal memory (EEPROM/Flash). This data locks the control unit and cannot be erased via the vehicle’s OBD interface. Professional repair requires direct access to the memory chip to clear this data record.

Another frequent issue is the “Internal Control Unit Error” message. This typically results from defective electronic components on the circuit board, such as voltage regulators, driver ICs for ignition circuits, or corrupted data in memory. Cold solder joints on SMD or BGA components can also cause intermittent or permanent failures.

How do you recognize a defect in control unit 95910-1C100?

A defect in airbag control unit 95910-1C100 usually manifests as a constantly illuminated airbag warning light on the instrument cluster. Additional clear indicators include loss of communication with diagnostic equipment or specific, non‑erasable error messages such as “Internal Control Unit Error.”

The most obvious symptom is the persistently lit airbag warning lamp. It fails to turn off after starting the vehicle, signaling a critical fault within the SRS system—often originating directly in the control unit itself.

Often, no diagnostic connection can be established with the airbag control unit. The device no longer responds to requests from workshop testers, making detailed in‑vehicle fault analysis impossible and strongly suggesting an internal malfunction.

If error codes like “Internal Control Unit Error” or faults related to ignition circuits appear—even though external components such as airbags and seatbelt pretensioners have already been inspected and confirmed intact—the root cause almost certainly lies within the control unit itself.

In which vehicles is control unit 95910-1C100 installed?

The airbag control unit with part number 95910-1C100 is specifically designed for the Hyundai Getz of the TB series. At Airbag24, we repair this control unit for the relevant model years, covering both the original version and the facelifted models.

Specifically, this component is used in the following Hyundai models:

Hyundai Getz TB (model years 2002–2005)

Hyundai Getz TB Facelift (model years 2005–2009)

The repair methodology for this control unit family is well-established, ensuring reliable restoration.

How is control unit 95910-1C100 professionally repaired?

Professional repair at Airbag24 follows a structured process. Upon receipt, the control unit is analyzed on a test bench to precisely identify the fault. Next, crash data is erased, defective electronic components are replaced, and a final functional test is conducted to ensure full plug-and-play compatibility with 2 years’ statutory liability for defects.

First and foremost, a thorough vehicle diagnosis is essential. The fault memory should be read out, and the resulting log attached to the removed control unit. This helps our technicians better understand the context of the fault.

After arrival at Airbag24, the control unit undergoes an initial inspection, verifying reported symptoms. The core of the repair involves addressing the root cause, which includes professionally erasing crash data directly from the memory chip and replacing faulty hardware such as driver ICs or voltage regulators.

Following restoration, a comprehensive final test is performed on the test bench. We confirm that the control unit operates flawlessly, communication functions perfectly, and is ready for installation. The repaired original unit can then be reinstalled in the vehicle without further coding.
