Airbag control unit with part number 95910-3J200

What is the function of the airbag control unit 95910-3J200?

The airbag control unit 95910-3J200 from Autoliv is the central control module of the occupant restraint system (SRS) in the Hyundai Veracruz EN (model years 2006–2011). It processes data from crash sensors, deploys airbags and seatbelt pretensioners in the event of a collision, and permanently stores relevant crash data in its internal memory.

As the “brain” of the passive safety system, this component continuously monitors all connected sensors and actuators. Upon impact, it determines within milliseconds which restraint systems need to be activated to provide optimal protection for occupants. After a crash, the unit is often electronically locked to prevent improper reuse.

Why does the control unit 95910-3J200 fail?

The most common cause of failure for the 95910-3J200 control unit is stored crash data following an accident, which permanently locks the device. Other defects arise from moisture ingress or the natural aging of electronic components such as capacitors and microcontrollers, leading to internal malfunctions.

A key feature of this control unit is its ability to store so‑called “hard codes” or crash data. Even in minor rear‑end collisions where neither airbags nor seatbelt pretensioners deploy, the unit may still record an internal fault and lock itself. This condition cannot be cleared using conventional diagnostic tools.

In addition, internal component failures can occur. Aging capacitors or malfunctions in the microcontroller can also result in total failure or erratic behavior, making repair unavoidable.

How do you recognize a defect in the 95910-3J200?

A defective airbag control unit 95910-3J200 primarily manifests as a constantly illuminated airbag warning light (SRS lamp). Additionally, communication with the control unit via a diagnostic tool is often impossible, or non‑erasable fault codes such as B1650 or B1620 are stored.

The most obvious sign is the persistently lit SRS warning light on the instrument cluster, indicating a critical fault in the restraint system that does not extinguish after starting the vehicle.

In the workshop, the defect often becomes apparent when the control unit is no longer accessible to diagnostic equipment. Alternatively, specific fault codes for Hyundai models—such as B1650 (Crash Recorded in 1st Stage Only-Side) or B1620 (Internal Fault)—are displayed and cannot be cleared.

A rarer but distinctive symptom may be a malfunctioning speedometer illumination or a faint glow of the warning light even when the vehicle is locked, suggesting an internal electronic fault.

How is the 95910-3J200 professionally repaired?

Professional repair of the 95910-3J200 control unit at Airbag24 includes diagnosis, complete erasure of stored crash data, replacement of defective electronic components, and a final functional test, restoring the unit to the fully operational condition of a new part.

After submitting the removed control unit to Airbag24, the repair follows a standardized, certified process:

1. Initial inspection and diagnosis: The unit is first examined for visible damage, followed by a comprehensive electronic analysis to identify the precise cause of the fault—whether it’s crash data or a component failure.

2. Repair: Depending on the diagnosis, stored crash data (“hard codes”) are irreversibly erased at the chip level. If a hardware defect is present, faulty components such as the microcontroller or capacitors are replaced with new, high‑quality parts.

3. Final testing and quality assurance: Following repair, the control unit undergoes a simulation test on a test bench to ensure all functions operate flawlessly and communication with diagnostic tools has been restored. Each repair comes with a 12‑month warranty.
