Airbag control unit with part number 95910-A6300

What is the function of the airbag control unit 95910-A6300?

The airbag control unit with part number 95910-A6300 is the central control module of the occupant safety system (SRS) in Hyundai vehicles, primarily in the i30 of the GD series. It processes signals from crash sensors to precisely and promptly deploy airbags and tighten seat belts in the event of a collision.

As an original OEM component from Hyundai, this SRS module is responsible for continuously monitoring the operational readiness of all safety‑related components. It communicates with the instrument cluster and reports system faults via the airbag warning light.

Why does the control unit 95910-A6300 fail?

The most common cause of failure for the 95910-A6300 control unit is stored crash data after an accident, which prevents further use. In addition, internal electronic malfunctions—indicated by fault codes such as B1620 (internal error) or B1102 (power supply)—can lead to system disruptions.

After an airbag deployment, the unit permanently stores crash data and locks itself. This is a manufacturer‑imposed safety measure, but it renders the unit unusable without professional repair. The repair involves resetting this stored data.

Another frequent reason is hardware defects on the circuit board. Fault code B1620 points to an irreparable internal fault, often caused by defective components. Code B1102 indicates power supply issues, which may originate either within the control unit itself or in the vehicle’s wiring harness.

External factors such as moisture, loose connectors, or damaged cables can also trigger malfunctions. Improper repair attempts in the past are another potential source of problems.

It’s important to note that similar part numbers like 95910-A6000, 95910-A6100, and 95910-S0000—also installed in the Hyundai i30 GD—often exhibit the same defects and can be repaired in the same manner.

How do you recognize a defect in the 95910-A6300?

The clearest sign of a malfunction is a continuously or intermittently illuminated airbag warning light on the instrument panel. Specific fault codes such as B1102 or B1620 can often be read out. Additional symptoms may include a non‑functioning clock or a flashing engine check light.

The airbag warning light is the primary indicator. It signals that the SRS is not functioning properly and might fail to deploy in the event of a crash.

During diagnostics at a workshop, fault codes directly related to the control unit are frequently retrieved. B1620 (internal error) and B1102 (low power supply) are typical for this vehicle series.

In some cases, accompanying symptoms may appear, including complete failure when the unit heats up, a non‑working clock display, or even a flashing engine check light indicating communication problems within the CAN bus system.

In which vehicles is the 95910-A6300 control unit installed?

The airbag control unit with part number 95910-A6300 is specifically used in Hyundai vehicles. It is the standard control unit for the second‑generation Hyundai i30 (GD series) throughout its entire production run, including the facelift model.

At Airbag24, we repair part number 95910-A6300 and related variants for the following models:

Hyundai:

i30 (GD generation, model years 2011–2015)

i30 Facelift (GD generation, model years 2015–2017)

How is the 95910-A6300 professionally repaired?

Professional repair at Airbag24 begins with an initial inspection to verify the fault. Depending on the cause, stored crash data is erased, or defective electronic components on the circuit board are replaced. Final tests ensure full functionality.

After submitting the removed control unit to Airbag24, our technicians perform a comprehensive analysis. They read out the fault memory to confirm reported codes such as B1620 or B1102 and inspect the unit for additional damage.

If the unit is locked due to an accident, the memory is reprogrammed to clear the crash data. For electronic faults, faulty components on the circuit board are identified and replaced with new, high‑quality parts.

Following repair, the control unit undergoes thorough testing to ensure it communicates flawlessly with the vehicle again and correctly executes all safety functions. We provide 2 years' statutory liability for defects on every repair.
