Airbag control unit with part number 95910-CM200

What is the function of the airbag control unit 95910-CM200?

The airbag control unit with part number 95910-CM200 is a central safety component in Hyundai models, primarily the Kona. It continuously monitors crash sensors and is responsible for precisely triggering the airbags and seatbelt pretensioners within milliseconds in the event of a collision, thereby protecting occupants.

As the brain of the passive safety system, the control unit constantly processes data from acceleration and angular velocity sensors. Upon detecting a collision, it sends ignition signals to the appropriate restraint systems.

It also stores all relevant system states and fault codes in its internal fault memory, which is crucial for diagnostics. Related part numbers often listed as compatible for the Hyundai Kona include 95910-J9100 and 95910-K4100.

What defects occur in 95910-CM200?

Defects in the 95910-CM200 control unit typically manifest as crash data stored in the internal memory after an accident, which can lock the system. Other causes include internal hardware failures such as defective passive components or broken solder joints, as well as communication failures that make diagnosis impossible.

The most common reason for service is the storage of crash data. After airbags or seatbelt pretensioners have been deployed, the control unit locks up and must be professionally reset to restore full functionality.

At the electronic level, defects may arise in passive components like capacitors and resistors, or in cold solder joints on the circuit board. These disrupt internal signal processing and result in persistent error messages.

A complete communication failure—where the control unit becomes unresponsive via the diagnostic interface—also indicates a severe internal hardware defect. Moisture damage caused by corrosion can likewise harm the electronics.

How do you recognize a defect in the 95910-CM200 control unit?

A defect in the 95910-CM200 airbag control unit almost always presents itself through the permanently illuminated airbag warning light on the instrument cluster. Additional signs include specific fault codes such as B1000, or a complete inability to communicate with a diagnostic tool during workshop testing.

The primary and unmistakable symptom is the persistently lit airbag warning light. This indicates a critical fault in the restraint system that endangers vehicle occupants.

Often, the fault memory cannot be cleared, or the control unit becomes completely inaccessible to diagnostic tools. This prevents accurate analysis of peripheral components such as sensors or the wiring harness.

Typical fault codes pointing to an internal control unit defect include, for example, B1000 (internal error). Messages like “Refer to manual/Passenger airbag” may also suggest a problem with the airbag assembly.

In which vehicles is the 95910-CM200 control unit installed?

The 95910-CM200 airbag control unit is specifically used in Hyundai vehicles. At Airbag24, we primarily repair this unit for Hyundai Kona models, both pre-facelift and facelift versions produced during the specified model years.

At Airbag24, we offer professional repair services for the following models:

Hyundai: Kona OS (2017–2020), Kona OS Facelift (2020–2023)

How does the repair of the 95910-CM200 proceed at Airbag24?

Professional repair of the 95910-CM200 at Airbag24 includes a detailed component-level diagnosis, electronic restoration of faulty parts, and safe resetting of stored crash data. Each repair step is documented and verified with a final functional test, including 2 years’ statutory liability for defects.

Upon receipt of the removed control unit at Airbag24, an initial visual inspection is performed under ESD conditions to detect external damage such as corrosion or burn marks. The electronics on the circuit board are then analyzed.

The core of the repair involves replacing defective components through SMD soldering and resolving contact issues. Simultaneously, data from the internal memory (EEPROM/Flash) is read out.

Stored crash data is securely and completely erased. Original vehicle data and serial IDs remain intact, so post-repair re‑learning in the vehicle is usually unnecessary.

Finally, the refurbished control unit undergoes a comprehensive functional test on a test bench. Following successful testing, it is returned to the customer with 2 years’ statutory liability for defects covering the completed repair.
