Airbag control unit with part number 95910-3B160

What is the function of Airbag Control Unit 95910-3B160?

The Airbag Control Unit 95910-3B160 is the central control module of the Supplemental Restraint System (SRS) in the Hyundai Equus VI. As a Siemens / Continental type 5WY66001, it processes signals from crash and occupancy sensors and determines whether to deploy airbags and seatbelt pretensioners, ensuring occupant safety in the event of an accident.

As a core component of the Supplemental Restraint System (SRS), this control unit is responsible for monitoring and controlling all passive safety devices. It maintains constant communication with sensors distributed throughout the vehicle.

In the event of a collision, the electronics analyze data from acceleration sensors within milliseconds. Based on this information, it decides which restraint systems—such as front or side airbags and seatbelt pretensioners—should be activated to provide optimal protection for occupants.

The specific hardware, often designated by the manufacturer as Siemens or Continental under type number 5WY66001, is precisely tailored to the vehicle architecture of the Hyundai Equus VI.

What defects occur in 95910-3B160?

The most common causes of failure for control unit 95910-3B160 include permanently stored crash data after an accident, internal hardware faults in components such as voltage regulators or memory chips, and complete loss of communication via the OBD interface. These issues require professional electronic repair.

After deploying airbags or seatbelt pretensioners, the control unit stores so‑called “crash data” or “hard codes.” This data permanently disables system functionality and cannot be erased using standard workshop diagnostic tools.

Another typical defect is an internal control unit malfunction, often logged in the fault memory. This indicates a failure on the circuit board, such as problems with the power supply, driver ICs, or the memory modules themselves.

In rare cases, external factors like moisture or corrosion can also damage the electronics, especially since the control unit is frequently installed in the underbody area.

The repair service covers related and compatible part numbers, including 95910‑3B150, 95910‑3B260, 95910‑3B270, 95910‑3B460, 95910‑3B470, 95910‑3B560, and 95910‑3B570.

How do you recognize a defect in 95910-3B160?

A defect in the Airbag Control Unit 95910-3B160 primarily manifests as the airbag warning light remaining constantly illuminated on the dashboard. Accompanying symptoms may include error messages such as “Check Airbag,” and communication with diagnostic equipment often becomes impossible. Error codes cannot be cleared.

The most obvious symptom is the persistently lit airbag warning light, which does not turn off after starting the vehicle—indicating a critical fault in the SRS.

In addition to the warning light, text messages may appear on the vehicle’s display instructing the driver to have the airbag system inspected at a workshop.

A clear technical indicator is when a workshop’s diagnostic tool cannot establish communication with the airbag control unit. The device fails to respond to requests via the OBD interface, suggesting a severe internal malfunction.

Even if communication remains possible, error codes referencing stored crash data or internal defects cannot be permanently erased. After attempting to clear them, the airbag light immediately reappears.

In which models is 95910-3B160 installed?

The Airbag Control Unit with part number 95910-3B160, along with its compatible counterparts, is specifically designed for the luxury sedan Hyundai Equus VI. At Airbag24, this SRS module is professionally refurbished for vehicles manufactured between 2009 and 2016.

At Airbag24, we repair the Airbag Control Unit with part number 95910-3B160 for the following specific vehicle model:

Hyundai: Equus VI / Centennial (VI) (model years 2009–2016)

How does the repair of 95910-3B160 proceed at Airbag24?

After removal and shipment to Airbag24, the 95910-3B160 control unit undergoes a detailed laboratory diagnosis. Depending on the issue, crash data is cleared via software reset, or hardware defects on the circuit board are repaired. A final functional test on the test bench confirms full operability before the unit is returned with 2 years' statutory liability for defects.

The process begins with the proper removal of the control unit from the vehicle. It is crucial to disconnect the vehicle battery beforehand to avoid safety risks. The module is then carefully packaged and shipped to Airbag24.

Upon arrival at the lab, an initial analysis is performed. Our technicians read out the fault memory and any available crash data, and conduct a visual and electrical inspection of the circuit board.

If the issue involves only crash data, the control unit is reset using specialized programming tools. For hardware defects, such as communication errors, repairs are carried out at the component level, replacing faulty parts like ICs or capacitors.

Each repaired control unit is tested on a dedicated test bench to simulate proper self‑test functionality and flawless communication. Following successful testing, the unit is returned with 2 years' statutory liability for defects covering the repair performed.
