Airbag control unit with part number 959102K050

What is the function of the airbag control unit 959102K050?

The airbag control unit 959102K050 is the central control module for the passive safety system in Kia Soul models of the AM and PS generations. It collects and processes data from acceleration and crash sensors to precisely and millisecond‑quickly deploy the airbags and seatbelt pretensioners in the event of a collision, thereby protecting occupants.

This device, also known as the SRS module (Supplemental Restraint System), serves as the brain of the entire airbag system. It maintains constant communication with various sensors distributed throughout the vehicle to ensure continuous monitoring of the driving conditions.

In addition to deploying restraint devices, the control unit is also responsible for system diagnostics. It continuously checks all connected components—such as airbags, seatbelt pretensioners, and sensors—for proper functionality and reports any malfunctions via the airbag warning light on the instrument panel.

Why does the control unit 959102K050 fail?

The most common reason for requiring repair of the control unit 959102K050 is stored crash data following an accident, which locks the system. Other causes include internal memory errors on the circuit board or disrupted communication, often triggered by defective components, wiring issues, or faulty connectors.

After a crash in which the airbags have deployed, the control unit stores so‑called crash data. This data remains permanently saved and, for safety reasons, prevents further operation of the system—even if all airbags have been replaced. The unit becomes “locked” and must be professionally reset.

A further typical defect is internal memory failure, often stemming from hardware problems with the memory chips on the control unit’s circuit board. These faults can occur even without an accident, causing the system to self‑diagnose as defective.

Workshop diagnostics must also account for potential external sources of error. Professional diagnostic tools help determine whether the root cause truly lies within the control unit or is due to broken wiring or faulty connectors.

How do you recognize a fault in the 959102K050?

A defective airbag control unit 959102K050 primarily manifests as a constantly illuminated airbag warning light on the dashboard. Additionally, the unit may stop responding to diagnostic requests, making communication with a diagnostic tool impossible. Error messages displayed on the screen are another clear indication.

The most definitive sign is the persistently lit airbag warning light. It fails to extinguish after starting the engine, indicating a serious, stored fault within the system.

An additional clear symptom appears during workshop diagnostics: when a technician attempts to read the fault memory, communication with the airbag control unit may fail entirely, rendering the unit inaccessible to diagnostic equipment.

In some vehicles, alongside the warning light, text messages appear on the instrument cluster display, signaling a fault in the airbag system. Moreover, stored crash data cannot be erased using standard diagnostic tools.

In which vehicles is the control unit 959102K050 installed?

The airbag control unit with part number 959102K050 is specifically designed for certain Kia models. It is mainly used in the first and second generation Kia Soul series. Airbag24 offers professional repair services tailored to these specific vehicle models.

At Airbag24, repairs for part number 959102K050 are available for the following vehicle models mapped in our system:

Compatibility extends to the first generation of the Kia Soul, known as the AM series, produced between 2008 and 2014.

The unit is also installed in the successor generation, the Kia Soul PS, manufactured from 2014 to 2019.

For successful repair and full functional restoration, exact matching of the part number on the removed control unit is crucial.

How does the repair of the 959102K050 proceed at Airbag24?

Upon receipt of the removed control unit 959102K050 at Airbag24, a professional initial inspection is conducted. The repair process includes erasing stored crash data and fully resetting the system. Following successful refurbishment and final testing, the unit is returned with 2 years' statutory liability for defects.

The process at Airbag24 is designed for safe and reliable repair. Once the control unit arrives at our facility, our technicians perform a thorough analysis to precisely identify the root cause of the fault, using professional diagnostic tools.

The core of the repair involves completely erasing the crash data stored in the device’s internal memory after an accident. At the same time, the control unit is restored to its factory settings, ensuring full functionality once again. In cases of internal memory failures, the defective hardware components on the circuit board are repaired.

Following the repair, each control unit undergoes an extensive functional test to confirm that it communicates flawlessly with the vehicle and fully meets all safety‑related requirements. We provide 2 years' statutory liability for defects on every repaired unit.
