Ferrari SF90 XX Stradale F173 airbag control unit repair

What is a Ferrari SF90 XX Stradale F173 airbag control unit?

In the Ferrari SF90 XX Stradale F173, the airbag control unit is the central control unit of the restraint system (SRS). It evaluates the signals from the crash sensors and, in an accident, decides within milliseconds which airbags and seatbelt pretensioners deploy. It tells you via the airbag warning light when it detects a fault.

The unit is installed in the Ferrari SF90 XX Stradale F173 (2023 to 2025). While the vehicle is in operation, it monitors the entire system continuously and therefore notices by itself when a component no longer responds.

If it has registered an accident, it stores crash data and locks itself. If the control unit fails, the Ferrari airbag system is no longer ready for use, and the light in the instrument cluster does not go out.

Why is the Ferrari SF90 XX Stradale F173 airbag control unit defective?

Most often the cause is crash data stored in the unit after an accident, even if no airbag deployed. Ageing electronic components, cold solder joints, moisture and corrosion on connectors, or voltage spikes, for example from a weak battery or jump-starting, are also possible.

An ordinary diagnostic tool cannot remove stored crash data. If the light stays on permanently, the fault memory cannot be cleared or the diagnostic tool cannot establish a connection, this points to a defective control unit.

Over the years components age, and solder joints become brittle through temperature changes and mechanical stress on the circuit board. If moisture gets into the connectors, corrosion and contact problems develop, which show up as communication errors. Voltage spikes can also damage individual components on the circuit board.

Common error codes for Ferrari SF90 XX Stradale F173 airbag control unit repair

On the Ferrari SF90 XX Stradale F173, the known error codes point to internal faults of the control unit and to a power supply that is too weak. They are read from the fault memory with a diagnostic tool.

A code can concern very different parts of the system: the control unit itself, the power supply, the wiring including connectors, or an individual airbag module. For the Ferrari SF90 XX Stradale F173 these codes are known:

• 01 → Internal fault in the control unit
• 06 → Battery voltage too low

The code alone does not reliably tell where the cause lies, because it does not reveal whether the control unit is really defective. So first have the fault memory read out so that the entries are available. The inspection then clarifies whether the fault is in the unit or elsewhere. The printout of the read-out supports this inspection if you enclose it with the unit.

What part numbers are available for the Ferrari SF90 XX Stradale F173 airbag control unit repair?

On the label of your control unit you will find the part number, which identifies the exact version. Depending on equipment and year of manufacture, the numbers also differ within the same model series.

There is no overview of known numbers for the Ferrari SF90 XX Stradale F173 so far. Remove the unit, read the number from the label and enter it when you create the repair order. This identifies your unit unambiguously. Whether it is actually defective is only shown by reading out the fault memory or by the inspection at Airbag24.

The path to repair: the fault memory is read out first. Then you disconnect the battery and remove the control unit. Next, create a repair order online and send in the unit. For inspecting, repairing and testing, Airbag24 usually allows 3–4 working days, plus the time for shipping.

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.
