Airbag control unit with part number 95910-2K350

What is the function of the airbag control unit 95910-2K350?

The airbag control unit 95910-2K350, manufactured by Continental/Mobis (e.g., part number 5WK44178), serves as the central control module for the occupant protection system in the Kia Soul AM (2008–2014). It analyzes data from crash sensors and, in the event of a collision, deploys airbags and pretensioners to safeguard vehicle occupants.

As the “brain” of the passive safety system, this control unit continuously processes signals from acceleration and pressure sensors distributed throughout the vehicle. It must determine within milliseconds whether an impact meets the criteria for triggering pyrotechnic restraint devices such as front and side airbags or seatbelt pretensioners.

Due to its critical role, the 95910-2K350 control unit is typically installed in a protected, central location within the vehicle—often beneath the center console in the center tunnel—to shield it from direct damage during a crash and ensure optimal communication with all relevant sensors.

What types of failures occur in the 95910-2K350?

The most common cause of failure for the 95910-2K350 control unit is the storage of crash data after an airbag deployment, which results in internal locking of the device. Other issues include internal hardware malfunctions on the circuit board, often indicated by error codes such as “Internal Control Unit Error” (similar to code B1620).

Following a crash, the control unit permanently writes a data record into its internal memory (EEPROM/Flash). This lock, known as “Crash Data Stored,” is a manufacturer‑imposed safety feature that prevents further use of the unit. Professional electronic repair can remove this data and restore the device to its original factory‑conditioned functionality.

Even without a crash, hardware defects may arise on the circuit board. Common causes include thermal stress or aging, leading to cold solder joints or failures in microcontrollers, voltage regulators, or driver circuits for ignition systems. Such faults are frequently diagnosed as internal control unit errors.

How do you recognize a fault in the 95910-2K350 control unit?

The primary symptom of a malfunctioning 95910-2K350 control unit is the persistent illumination of the airbag warning light on the instrument cluster. Additionally, diagnostic trouble codes such as “Crash Data Stored” or “Internal Control Unit Error” appear in the fault memory. In some cases, communication with the control unit via a diagnostic tool becomes impossible.

The airbag warning light is the clearest indicator for the driver, signaling that the entire occupant protection system is inoperative—a condition that could have serious consequences in another accident and constitutes a significant defect during vehicle inspection.

A qualified workshop can use diagnostic equipment to read the fault memory. Error codes like “Crash Data Stored” or “EEPROM Error” directly point to the need for repair. If the control unit is completely unresponsive, this often indicates a severe internal hardware failure.

In which vehicles is the 95910-2K350 control unit installed?

The airbag control unit with part number 95910-2K350 is specifically used in the first-generation Kia Soul (model AM). At Airbag24, we offer professional repair services for this control unit across all engine variants of this model series produced between approximately 2008 and 2014.

At Airbag24, repair services for the 95910-2K350 control unit are available for the following vehicle model:

Kia Soul (AM series, circa model years 2008–2014)

How does the repair process for the 95910-2K350 work?

At Airbag24, repairing the 95910-2K350 begins with a precise laboratory diagnosis of the submitted unit. Depending on the findings, stored crash data is professionally erased, or defective electronic components on the circuit board are replaced. Following a final test on a simulator, the fully functional control unit is returned to the customer.

The process starts with the proper removal of the control unit from the vehicle, requiring battery disconnection and adherence to a safety waiting period. Please send the unopened unit securely packaged, as improper opening attempts may complicate the repair process.

In the lab, our technicians conduct a thorough analysis. During the crash data reset, the memory contents are read, the lock is removed, and the original clean data state is restored. For hardware-related issues, repairs are performed at the component level—for example, replacing or resoldering faulty ICs.

Each repaired unit undergoes comprehensive final testing to ensure flawless communication and correct operation of all ignition circuits. You receive 2 years' statutory liability for defects on the completed repair.
