Airbag control unit with part number 220244-105

What does the airbag control unit 220244-105 do?

The airbag control unit 220244-105 acts as the central unit of the restraint system (SRS) in vehicles from Ferrari. It evaluates the crash sensors, decides within milliseconds in a crash whether airbags and seatbelt pretensioners are triggered, and locks itself after a crash once it has stored crash data.

Monitoring runs continuously in the background. If the unit detects a fault, it records it and makes it visible via the airbag warning light in the instrument cluster.

The sensors deliver their measured values to the control unit via wiring. Only if this evaluation works correctly will the restraint systems trigger correctly in an emergency.

Why does the control unit 220244-105 fail?

Stored crash data is the most common cause, even if no airbag has deployed. A standard diagnostic tool cannot erase it, and Airbag24 removes it during the repair.

An event in the memory, however, does not yet say whether the electronics have also been damaged. This point is only clarified on the test bench, not by the crash data alone.

Aged electronic components, cold solder joints, moisture and corrosion on plug connections, and voltage spikes also play a role. Such voltage spikes arise, for example, from a weak battery or a jump start.

How can you tell that the 220244-105 is defective?

A defect in the control unit shows when the airbag warning light in the instrument cluster lights up, whether permanently or intermittently. In addition, a fault message appears in the instrument cluster, the diagnostic tool has no connection, and the fault memory cannot be cleared.

• The airbag warning light in the instrument cluster lights up permanently or intermittently
• A fault message appears in the instrument cluster
• The diagnostic tool has no connection to the control unit
• The fault memory cannot be cleared

In an emergency, airbags and seatbelt pretensioners may possibly fail to trigger in the event of such a defect. For that reason, a lit warning light should be checked or read out promptly.

Comparing the part number on the label of the removed unit with this page ensures that you have the right unit in front of you. Please also have the fault memory read out, because the result shows whether the control unit is defective or whether a plug or cable is the cause.

How does the repair of the 220244-105 work?

Processing at Airbag24 usually takes 3–4 working days. First have the fault memory read out and enclose the log, then disconnect the battery. Only then remove the control unit, create a repair order online and send the unit in.

Airbag24 examines the unit on the test bench, replaces defective components, erases stored crash data and carries out a function test.

Afterwards, your own unit is sent back to you. Our repairs come with 2 years' statutory liability for defects. The repaired control unit comes back with all vehicle data and is ready for use as soon as it is refitted — no coding or programming is required.

How does the control unit 220244-105 get to Airbag24?

You send the control unit 220244-105 in as a parcel or book a UPS collection for an extra charge. After the repair, Airbag24 returns it to you by UPS.

Please put the printed repair order into the parcel and pack the unit shock-resistant.
