Airbag control unit with part number 50567775

What is the function of Airbag Control Unit 50567775?

The airbag control unit with part number 50567775 is the central control module of the occupant restraint system (SRS) in the Alfa Romeo Giulia 952. It processes data from crash sensors and, within milliseconds, determines whether and which airbags or seatbelt pretensioners need to be deployed to provide optimal protection for vehicle occupants in the event of a collision.

This unit, also known as the SRSCM (Supplemental Restraint System Control Module), continuously monitors all connected components of the restraint system. These include front, side, and head airbags, seatbelt pretensioners, seat occupancy detection, as well as external acceleration and pressure sensors. Upon impact, the microprocessor inside the control unit analyzes the severity and direction of the collision to ensure targeted, situation-appropriate activation of the safety systems.

Why does control unit 50567775 fail?

The most common cause of failure for control unit 50567775 is the storage of crash data after an accident. Even in minor collisions where not all airbags deploy, the unit becomes internally locked. In addition, purely electronic faults in internal components such as microcontrollers, memory chips, or voltage regulators can also be responsible.

After airbags or seatbelt pretensioners are deployed, accident data is permanently stored in the internal memory (EEPROM/Flash). This is a manufacturer‑specified safety measure that typically requires replacing the entire control unit. However, professional repair can remove this lock by selectively erasing the crash data.

Electronic defects represent another major cause. Thermal stress and aging can lead to hairline cracks at BGA chip solder joints (microcontrollers, memory). Faulty capacitors, power supply voltage regulators, or defective drivers for ignition circuits may also result in total failure or intermittent malfunctions.

External factors such as moisture or water damage are particularly critical, since the control unit is often installed in the center tunnel area. Corrosion on connectors or directly on the circuit board can cause communication errors or short circuits. Likewise, issues with the vehicle’s electrical supply—such as a weak battery or faulty ground connections—can trigger internal faults in the control unit.

How do you recognize a defect in the airbag control unit?

A defect in control unit 50567775 almost always manifests as a constantly illuminated airbag warning light (SRS indicator) in the instrument cluster. Additionally, the fault memory typically displays entries like “Crash Data Stored” or “Internal Control Unit Error.” In some cases, the control unit becomes inaccessible to diagnostic tools.

The primary and most definitive symptom is the persistent SRS warning light that fails to extinguish after the engine starts. This alerts the driver that the entire occupant restraint system is either completely disabled or severely compromised, meaning it would not reliably activate in the event of a crash.

During workshop diagnostics, specific fault codes can be read. Common entries include “Crash Data Stored,” which directly results from an accident, or general errors such as “Control Unit Fault” (internal control unit error). These indicate problems with the module’s internal hardware or software integrity.

Another clear sign is when the diagnostic tool cannot establish communication with the airbag control unit. The module no longer responds to requests over the CAN bus, suggesting a serious internal fault, a power supply issue, or an interruption in the communication lines.

In which vehicles is control unit 50567775 installed?

The airbag control unit with part number 50567775 is primarily used in various versions of the Alfa Romeo Giulia. This includes both the first generation of the 952 series starting from model year 2016 and the facelifted models. Repairs are available for all these vehicle variants.

At Airbag24, we repair control unit 50567775 for the following Alfa Romeo models:

Giulia (952 series) from 2016 to 2023

Giulia (952 series facelift) from 2023 onward

How is control unit 50567775 professionally repaired?

Professional repair begins upon receipt at Airbag24 with an initial inspection and diagnosis. Depending on the nature of the fault, either the stored crash data is selectively erased, or a comprehensive electronic overhaul is performed at the component level. Final tests confirm full functionality. We offer a 12-month warranty on all repairs.

The process ideally begins with a fault diagnosis at your workshop to rule out external causes such as defective sensors or wiring harnesses. The control unit is then removed and securely packaged, along with a detailed description of the fault, and sent to us.

If stored crash data is involved, our technicians will read the internal memory of the control unit, delete the crash records, and write the cleaned dataset back into the unit. The control unit is then fully functional again and free of any locks.

In cases of an internal electronic fault, a detailed analysis of the circuit board is performed. Defective components—such as microcontrollers, memory chips, capacitors, or driver ICs—are identified and replaced with new, high-quality parts. Cold solder joints are also professionally reworked.

Following each repair, the control unit undergoes a comprehensive functional test on a specialized test bench. We simulate the vehicle environment to verify proper communication and the correct operation of the ignition circuits. Only after a successful test is the unit approved for return shipment.

What shipping options are available?

For repairing your control unit at Airbag24, you can either send it to us free of charge or arrange a convenient UPS pickup. For the return shipment, you can choose between free UPS standard delivery, faster express shipping, or cash-on-delivery. Personal collection is also possible.

For the outbound shipment, you have two convenient options: you can send the package yourself or book a paid UPS pickup at your preferred location (e.g., home or workshop).

Upon completion of the repair, we offer several return‑shipping options:

Free UPS standard delivery (1–3 business days)

UPS express delivery (1–2 business days)

UPS standard delivery with cash-on-delivery (1–3 business days)

UPS express delivery with cash-on-delivery (1–2 business days)

What are the benefits of repairing the 50567775?

Repairing the airbag control unit 50567775 is an extremely cost-effective and sustainable alternative to an expensive new part. Not only do you save significantly on costs, but you also retain your vehicle’s original coding, eliminating the need for time-consuming reprogramming at the workshop.

The biggest advantage is the cost savings. A new control unit from the manufacturer can cost several hundred euros, whereas a professional repair or a crash-data reset often costs only a fraction of that amount. The savings compared to purchasing a new unit—including coding—can reach up to 70%.

A key technical benefit is preserving your vehicle’s original configuration. Since your existing control unit is repaired, all vehicle-specific data and coding remain intact. After reinstallation, the unit is immediately ready to use (“plug-and-play”), without requiring costly and time‑consuming reprogramming at an authorized dealer.
