Airbag control unit with part number 220244103

What is the function of Airbag Control Unit 220244103?

The airbag control unit with part number 220244103 is the central control module for the Supplemental Restraint System (SRS) in exclusive Ferrari models. It analyzes data from acceleration sensors and, within milliseconds, determines whether to deploy airbags and seatbelt pretensioners. Another verified OEM number for this component is 277245.

Technically speaking, reference 220244103 is an original OEM control unit (Original Equipment Manufacturer), specifically engineered to meet the dynamic demands of high-performance vehicles such as the Ferrari 458. Its primary role is continuous monitoring of all safety‑related components of the Supplemental Restraint System (SRS).

This includes front, side, and head airbags, pyrotechnic seatbelt pretensioners, and the crash sensors distributed throughout the vehicle. The control unit acts as the system’s “brain,” precisely managing the sequence and intensity of restraint device deployment in the event of a collision to provide optimal occupant protection.

Why does control unit 220244103 fail?

The most common cause of failure for control unit 220244103 is the storage of crash data following an accident. This irreversible lockout serves as a safety precaution. Additionally, purely electronic faults—such as capacitor failures or PCB damage—can lead to total malfunction or erratic behavior even without a crash.

After a collision, even a minor one, the control unit stores so‑called crash data. These records permanently disable the module to prevent re‑use of a potentially damaged system. The SRS warning light illuminates, and the system remains deactivated until the unit is repaired or replaced.

Beyond accidents, aging or thermal stress can also result in hardware defects. Faulty solder joints, failed capacitors, or defective memory chips on the circuit board are typical electronic causes. Such issues often manifest as communication problems or internal error codes that appear during diagnostics.

How do you recognize a fault in 220244103?

A defect in control unit 220244103 is primarily indicated by a continuously illuminated or flashing SRS warning light in the cockpit. Another clear sign is when the control unit becomes unresponsive to diagnostic tools—no communication occurs at all. In this state, the entire airbag system is inoperative.

The most noticeable and serious symptom is the activated SRS warning light (Supplemental Restraint System). This signals a critical fault in the occupant protection system, indicating that airbags and seatbelt pretensioners would not deploy in the event of a crash. Continuing to drive under these conditions is strongly discouraged for safety reasons.

In the workshop, the suspicion is often confirmed when no connection can be established with the control unit. Diagnostic equipment receives no response from the module, complicating troubleshooting and pointing directly to an internal fault within the control unit. Error codes indicating an “internal control unit fault” are also definitive indicators.

In which vehicles is control unit 220244103 installed?

Part number 220244103 and its alternative OEM number 277245 are specifically designed for various models in the Ferrari 458 series. At Airbag24, we offer professional repair services for these exclusive sports car control units, restoring original functionality and safety while avoiding the high cost of a new part.

At Airbag24, we repair control units with part number 220244103 for the following high-performance Ferrari models:

Ferrari 458 Italia F142 (model years 2009–2015)

Ferrari 458 Speciale F142 (model years 2013–2016)

Compatibility has been verified for these specific models. As these are safety‑critical components, it is essential that the correct control unit is installed and fully operational in your vehicle.

How does the repair of 220244103 work?

Repair at Airbag24 follows a standardized “repair-and-return” process. Upon submission, your original 220244103 control unit undergoes a thorough incoming inspection. Depending on the nature of the fault, crash data is erased or defective electronic components on the circuit board are replaced. After a successful final test, you receive your refurbished unit back.

Following removal from the vehicle and shipment to Airbag24, the professional repair process begins. First, our technicians conduct a systematic analysis to pinpoint the exact cause of the issue—whether it’s blockage due to crash data or a specific hardware defect.

In the next step, the actual repair takes place. Stored crash data is securely and completely erased at the chip level. If electronic components such as capacitors or other modules are defective, they are carefully desoldered and replaced with new, high-quality parts.

After the repair, the control unit undergoes extensive functional testing to ensure flawless operation across all systems. The repaired unit is typically “plug-and-play” and can be reinstalled in the vehicle without additional programming. We provide 2 years' statutory liability for defects on every repair.
