Airbag control unit with part number 95910-2R000

What is the function of the airbag control unit 95910-2R000?

The airbag control unit with part number 95910-2R000 is the central control module for the occupant protection system (SRS) in certain Hyundai models. It processes data from the acceleration sensors and, in the event of a crash, determines whether and which airbags or seatbelt pretensioners need to be deployed to protect the occupants.

This component, also known as the SRS module (Supplemental Restraint System), continuously monitors all connected ignition circuits, sensors, and internal system integrity. During each drive, the control unit performs a self-test. If any system faults are detected, the airbag warning light on the instrument cluster illuminates to alert the driver.

The proper functioning of this control unit is safety-critical. It is responsible for activating the passive safety systems at the crucial moment while preventing false activations under normal driving conditions.

Why does the control unit 95910-2R000 fail?

The most common causes of failure for the control unit 95910-2R000 are stored crash data after an accident and internal electronic defects. After an airbag deployment, the unit locks up and must be reset. Hardware defects often affect components such as voltage regulators or driver ICs on the circuit board.

A very common reason for a persistently illuminated airbag warning light is the storage of crash data in the internal EEPROM memory. Even if the deployed airbags and seatbelt pretensioners have been replaced, the control unit remains locked until this data is professionally erased. A so‑called crash reset is then unavoidable.

In addition, purely electronic faults can occur. These include defective components on the circuit board, cold solder joints caused by thermal stress and vibrations, or damage to the communication interface (CAN/K‑Line drivers). In some cases, moisture can also lead to corrosion and malfunctions. The alternative OE reference number for this component is 2R959-10000.

How do you recognize a defect in the 95910-2R000?

A defect in the airbag control unit 95910-2R000 primarily manifests as a permanently illuminated airbag warning light (SRS lamp). Other clear indicators include loss of communication with the diagnostic tool and the presence of an internal control unit fault in the vehicle’s fault memory.

The most obvious symptom is the airbag warning light remaining on even when the engine is running. In some cases, the fault may only appear sporadically, with the light turning on and off intermittently.

A specific sign of an internal self-test error is when the airbag lamp illuminates approximately 30 seconds after the engine starts. This indicates that the internal monitoring routine has detected a fault.

A serious symptom is when the control unit becomes unresponsive via the diagnostic port. Workshop testers can no longer establish a connection, making precise fault diagnosis impossible and pointing to a problem with the power supply or the device’s communication stage.

After an accident in which airbags were deployed, the warning light also remains on. This signals the need to erase the crash data stored in the control unit to restore full system functionality.

In which vehicles is the 95910-2R000 installed?

The airbag control unit with part number 95910-2R000 is mainly used in Hyundai vehicles. At Airbag24, we repair this control unit primarily for the Hyundai ix55 of the EN series, as well as other models such as the Hyundai i30cw, where this component has been confirmed to be installed.

Our data and experience in the aftermarket repair sector confirm its use in the following models:

Hyundai ix55 EN (approximately model years 2009–2011)

Hyundai i30cw FD (station wagon)

Before removal and shipment, it is essential to verify the part number on the control unit’s label to ensure an exact match. The installation location is typically in the front area of the vehicle, usually in the center tunnel ahead of the center console.

How is the 95910-2R000 professionally repaired?

A professional repair at Airbag24 includes fault analysis, resetting the crash data, and repairing the electronics. Defective components are replaced, and the software is restored to its pre-crash state. A final functional test on the test bench ensures the quality of the repair.

Once the control unit arrives at our facility, technicians conduct a thorough incoming inspection. They check communication and read out the fault memory to verify the symptoms described by the customer.

The core of the repair, depending on the fault pattern, consists of two main tasks: erasing the crash data from memory (EEPROM/Flash) or repairing the hardware. During a crash reset, the control unit is electronically restored to its factory‑default state, while retaining the vehicle‑specific coding.

In cases of electronic faults, defective components such as driver ICs, voltage regulators, or faulty solder joints on the circuit board are identified and professionally replaced. A comprehensive final test is then performed on a test bench to ensure communication capability and flawless functionality across all systems. We provide 2 years' statutory liability for defects on every repair.
