Airbag control unit with part number 407959655

What is the function of Airbag Control Unit 407959655?

The airbag control unit with the original Lamborghini part number 407959655, also known by the Bosch reference 0 285 001 930, is the central control module of the passive safety system (SRS) in the Lamborghini Gallardo. Its primary task is to process sensor data so that, in the event of a collision, the airbags and seatbelt pretensioners are deployed precisely and within seconds.

Technically speaking, this module serves as the brain of the entire restraint system. It continuously receives and processes signals from various crash and acceleration sensors distributed throughout the vehicle.

Based on this data, the control unit determines whether an accident has occurred that necessitates activation of the passive safety components. It ensures that the correct components are triggered at the right time to provide optimal protection for occupants.

Why does control unit 407959655 fail?

The most common reason for failure of control unit 407959655 is the storage of crash data after an airbag deployment. The manufacturer intentionally locks the module to force a diagnostic check. In rarer cases, internal hardware defects in electronic components may also be responsible.

Following an accident in which the airbags or seatbelt pretensioners have been activated, the control unit writes a permanent record into its internal memory. This "crash lock" causes the airbag warning light to remain illuminated permanently, indicating that the system is reported as inactive.

This is a safety measure designed to prevent reuse without professional inspection. Repair involves professionally erasing this data and restoring the control unit to full functionality.

It’s important not to confuse this control unit with similar part numbers such as 4G0959655B, which is used in the Lamborghini Huracán. Each model requires a specific control unit revision for proper operation.

How can you recognize a defect in control unit 407959655?

A defect in airbag control unit 407959655 typically manifests through clear symptoms. The most noticeable sign is the permanently illuminated airbag warning light on the dashboard. Additionally, communication with the control unit via a diagnostic tool often becomes impossible, making it impossible to read fault codes.

The persistently lit airbag warning light is the primary indication for the driver that there is a problem with the SRS system. The light does not extinguish even after restarting the engine.

Another critical symptom is the complete loss of diagnostic communication. Workshops can no longer access the control unit with their diagnostic equipment to read or clear errors—the unit fails to respond to requests.

As long as this fault persists, the vehicle is considered unsafe for road use. This inevitably leads to issues during the main inspection, since a functioning airbag system is a mandatory requirement for operating approval.

How is control unit 407959655 professionally repaired?

Professional repair of control unit 407959655 at Airbag24 focuses on safely erasing stored crash data. Upon submission, the module is analyzed, the data lock is removed, and the software is reset. Subsequently, full functionality is verified, ensuring the device can be safely reinstalled in the vehicle. All repairs come with a 12-month warranty.

After removal from the vehicle and shipment to Airbag24, the control unit undergoes a standardized process. First, the fault memory is read to confirm the exact cause of the defect—most commonly, the stored crash information.

The core of the repair is an electronic procedure that clears the crash data from the control unit’s memory. This process restores the module to its pre‑accident state and deactivates the airbag warning light.

This process is based on expertise gained from over 20 years of experience and more than 20,000 repairs performed. Following successful data recovery, the control unit is thoroughly tested to ensure it can once again manage a fully functional and safe restraint system.
