Airbag control unit with part number 95910-3B460

What is the function of the airbag control unit 95910-3B460?

The airbag control unit 95910-3B460 from Siemens is the central control module for the occupant safety system (SRS) in the Hyundai Equus VI. It continuously monitors the crash sensors and is responsible for precisely and promptly deploying the airbags and seatbelt pretensioners in the event of a collision, thereby protecting the occupants.

As the brain of the safety system, this module processes data from the acceleration sensors distributed throughout the vehicle. When it detects a collision requiring deployment, it sends ignition signals to the relevant pyrotechnic components, such as front, side, or head airbags, as well as to the seatbelt pretensioners.

A technical feature of this control unit is its use of an external memory chip, type 95080 EEPROM. This memory permanently stores not only the vehicle configuration but also all relevant event data, including so‑called crash data after an accident.

Why does the airbag control unit 95910-3B460 fail?

The most common cause of failure for control unit 95910-3B460 is the storage of crash data in the external 95080 EEPROM following an airbag deployment. This permanently locks the device. Other defects include internal electronic malfunctions that can lead to total failure or communication issues.

After an accident in which airbags or seatbelt pretensioners have been activated, the control unit writes an irreversible data record—the crash data—into its memory. This lockout is intentionally designed by the manufacturer to prevent further use of a potentially damaged unit. The airbag warning light then remains illuminated continuously.

In addition to being locked by crash data, hardware defects on the circuit board may also occur. These include failures of voltage regulators, faulty CAN‑bus drivers that prevent communication with diagnostic tools, or cold solder joints caused by thermal stress and vibrations over time.

The repair process is identical across an entire family of control units for the Hyundai Equus VI. In addition to 95910-3B460, this includes part numbers 95910-3B150, 95910-3B160, 95910-3B260, 95910-3B270, and 95910-3B470.

How do you recognize a defect in 95910-3B460?

A defect in the airbag control unit 95910-3B460 primarily manifests as a permanently illuminated airbag warning light (SRS lamp) in the instrument cluster. Often, communication with the control unit via OBD diagnostics becomes impossible, or error codes such as “control unit internal error” are logged.

The clearest indication is the active SRS warning light. It does not extinguish after starting the engine or reappears shortly thereafter. This signals a critical fault in the restraint system that requires immediate inspection.

Another symptom is complete loss of diagnostic communication. If a workshop attempts to read the fault memory, no response is received from the airbag control unit. This points to a severe internal electronic damage.

If error codes can be read, entries such as “component defective,” “airbag internal error,” or “crash data stored” directly indicate a defect within the control unit itself. Especially after an accident, the entry related to crash data serves as a reliable indicator of a locked module.

In which vehicles is 95910-3B460 installed?

The airbag control unit with part number 95910-3B460 and its compatible variants are specific to the luxury sedan Hyundai Equus VI. At Airbag24, this module is professionally refurbished for the corresponding model years.

At Airbag24, we repair this control unit for the following model:

Hyundai Equus VI (also known as Equus Centennial), approximately model years 2009–2016

The repair covers the entire control unit family for this model. In addition to 95910-3B460, this includes part numbers 95910-3B150, 95910-3B160, 95910-3B260, 95910-3B270, and 95910-3B470.

How is 95910-3B460 professionally repaired?

Professional repair at Airbag24 involves diagnosing the submitted control unit, eliminating the root cause of the fault at the component level, and conducting a final functional test. The focus is on properly erasing crash data from the 95080 EEPROM and restoring the electronics.

Once the removed control unit arrives at Airbag24, it undergoes a thorough incoming inspection. First, a visual check is performed for external damage, moisture, or improper opening attempts. Subsequently, an attempt is made to read the fault memory, provided communication is still possible.

The core of the repair lies in processing the external 95080 EEPROM. Our technicians extract the memory chip, analyze the data set, and replace the crash dump with a clean, factory‑compliant data version (“Clear File”). In cases of communication problems or internal faults, additional components such as voltage regulators or CAN drivers are inspected and replaced if necessary.

After repair, the control unit is tested on a specialized test bench to ensure flawless functionality across all systems. The repaired module then performs just like a brand-new part. We provide a 12-month warranty on every repair.

What shipping options does Airbag24 offer?

For fast and hassle-free processing, you can either send your defective control unit yourself or arrange a convenient UPS pickup. For returning the repaired unit, we offer free standard shipping as well as various express and cash-on-delivery services.

For sending the item back, you have two free options: you can ship it to us yourself or drop it off at a local location. Alternatively, you can book a UPS pickup from your preferred location—such as a workshop or your home—through our portal.

Following successful repair, the returned unit is shipped back free of charge via UPS Standard (1–3 business days). If you need faster delivery, we offer UPS Express shipping (1–2 business days) for an additional fee. Both options are also available with cash-on-delivery. Of course, you can also pick up the repaired part in person at our facility.
