Airbag control unit with part number 95910-3B150

What is the function of the Airbag Control Unit 95910-3B150?

The Airbag Control Unit 95910-3B150 is the central control module of the restraint system (SRS) in the Hyundai Equus VI (2009–2016). It is a Siemens‑manufactured module with the internal identifier 5WK42995, responsible for processing sensor data and activating airbags and seatbelt pretensioners.

As the “brain” of the passive safety system, this control unit continuously processes information from acceleration and side‑impact sensors. In the event of a collision, it determines within milliseconds which restraint systems—such as front or side airbags—should be deployed to provide optimal occupant protection.

In addition, the module stores all system‑relevant fault codes and, in the case of an accident, permanently records crash data. These data can be retrieved via a diagnostic interface (OBD), provided the unit remains communicative. The software ID is typically 95080.

Why does the 95910-3B150 control unit fail?

The most common cause of failure for the 95910-3B150 control unit is the storage of crash data after an accident, which results in an intentional, irreversible lockout of the system. Additionally, hardware defects caused by aging, moisture, or thermal stress can lead to complete failure.

After an airbag deployment, the control unit is internally locked (“hard codes”). This is a manufacturer‑imposed safety measure that prevents reuse without professional inspection and repair. Erasing these stored data is a critical part of the repair process.

Electronic components such as processors, memory chips (EEPROM), or capacitors can degrade over time due to heat and vibration inside the vehicle. Moisture ingress through body panel leaks can also cause corrosion on the circuit board, leading to total failure.

This control unit is also known under similar part numbers, which are often interchangeable as long as ECU compatibility is verified. These include variants 95910-3B160 (5WY66001), 95910-3B260 (5WY66002), 95910-3B270, 95910-3B460, and 95910-3B470.

How do you recognize a defect in the 95910-3B150?

A defect in the 95910-3B150 control unit primarily manifests as a constantly illuminated airbag warning light on the dashboard. Another clear indication is the lack of communication with the diagnostic tool, preventing fault codes from being read or cleared.

The airbag warning light fails to turn off after starting the vehicle or remains steadily lit after about 30 seconds. This indicates that the self‑test has failed and the entire restraint system is non‑functional in an emergency.

If a workshop attempts to read the system via the OBD interface, a communication error is often reported. The control unit no longer responds to requests, suggesting a severe internal hardware failure.

The fault memory may contain specific error codes pointing directly to the control unit itself, such as “Side Sensor Error,” “Driver Airbag Error,” or persistent “Hard Codes” following an accident. In some cases, the unit may even completely fail when overheated.

In which vehicles is the 95910-3B150 installed?

The Airbag Control Unit with part number 95910-3B150 and its variants is specifically designed for the sixth‑generation Hyundai Equus luxury sedan. Repair services are offered exclusively for this premium vehicle model.

Hyundai Equus VI (model years 2009–2016)

How does Airbag24 perform the repair of the 95910-3B150?

At Airbag24, we carry out professional electronic refurbishment of the control unit. The process includes an initial diagnosis, targeted hardware repairs, and secure erasure of crash data. Following successful final testing, the unit is returned ready for installation, backed by 2 years' statutory liability for defects.

Once the control unit arrives at Airbag24, technicians conduct a thorough diagnostic examination, checking for typical fault patterns, pre‑existing damage caused by moisture, or improper repair attempts.

The core of the repair lies in restoring the component level. This involves erasing crash data from the internal EEPROM memory and, if necessary, replacing defective parts such as the Siemens chip or capacitors, returning the device to its original condition.

Since the original control unit is repaired, it becomes fully functional immediately upon reinstallation. Recoding or reprogramming of the vehicle is unnecessary, saving both time and costs.
