Airbag control unit with part number 95910-3M350

What is the function of the airbag control unit 959103M350?

The airbag control unit with part number 959103M350 is the central SRS diagnostic and control module for the Hyundai Genesis DH (2014–2017). Its task is to evaluate signals from crash sensors and, in the event of an accident, precisely activate life-saving restraint systems such as airbags and seatbelt pretensioners.

This module, often referred to as the SRS computer diagnostic-control module, serves as the brain of the vehicle’s entire passive safety system. It continuously monitors all connected components—from impact sensors at the front and sides of the vehicle to seatbelt pretensioners and individual airbag modules.

The control unit’s electronics typically come from leading manufacturers such as Bosch, Delphi, TRW, or Continental. In a collision, its internal logic determines within milliseconds which components need to be activated to provide optimal protection for occupants.

What defects occur in the 959103M350?

The most common defect of the 959103M350 control unit is the storage of crash data, which permanently locks the module. Other typical failures include complete refusal to communicate with diagnostic tools, as well as internal hardware malfunctions in electronic components—often occurring after accidents, even without airbag deployment.

A primary cause of failure is stored crash events. Even minor collisions that trigger only the seatbelt pretensioners or result in rear-end damage leave an irreversible entry in the control unit’s memory. This “crash lock” prevents further use and blocks vehicle approval during the main inspection (TÜV).

Another serious defect is a complete loss of communication. The control unit becomes unreachable via the diagnostic interface, indicating a severe electronic fault on the circuit board—potentially caused by moisture damage or prior improper repair attempts.

How can you recognize a defect in the 959103M350?

A defective 959103M350 airbag control unit primarily manifests as the airbag warning light constantly illuminated on the dashboard. Additionally, diagnostic tools may fail to connect to the control unit, or specific error codes such as “faulty airbags” or “fuel shut-off valve” may appear.

The most obvious symptom for the driver is the persistent activation of the airbag warning light. This light does not extinguish after starting the engine, signaling a critical safety-system fault that requires immediate inspection at a workshop.

During diagnostics at the workshop, it often becomes apparent that the control unit is no longer responsive. Attempts to read or clear the fault memory fail because no communication can be established.

Furthermore, additional specific error messages may appear in the instrument cluster or in the fault memory of other control units. Messages related to faulty airbags, the seat-mounted airbag, or the fuel shut-off valve could also point to an internal issue within the central airbag module.

In which models is the 959103M350 control unit installed?

The airbag control unit with part number 959103M350 is specifically designed for the Hyundai Genesis model series DH. It is used in model years 2014 through 2017, though it has also been tested and offered for vehicles dating back to 2013.

At Airbag24, we repair the 959103M350 control unit for the following vehicle model: Hyundai Genesis DH (model years 2014–2017).

How does the repair of the 959103M350 proceed at Airbag24?

Professional repair at Airbag24 includes analyzing the submitted control unit, erasing stored crash data, and restoring any defective electronic components. Following a final functional test, the module is fully operational and ready for installation. We provide 2 years' statutory liability for defects on every repair.

After receiving the removed control unit at Airbag24, specialized technicians perform an initial inspection to determine the exact cause of the fault. This ensures both software blockages caused by crash data and potential hardware damage are identified.

The core of the repair involves removing crash data from the module’s internal memory and restoring the original factory configuration. If components on the circuit board are damaged, they are expertly replaced.

Finally, the repaired control unit undergoes comprehensive testing to guarantee flawless communication and proper functioning of all system components. The module can then be reinstalled in the vehicle without further programming.
