Airbag control unit with part number 295799

What does the airbag control unit 295799 do?

The airbag control unit 295799 is the central control unit of the restraint system (SRS) for Ferrari. It evaluates the signals from the crash sensors and, in an accident, decides within milliseconds which airbags and seatbelt pretensioners to trigger. At the same time it monitors the system continuously and reports faults via the airbag warning light.

While driving, the unit continuously checks whether sensors, wiring and control are in order. This check runs in the background without any action required from you.

After an accident the unit stores crash data and locks itself.

Why does the control unit 295799 fail?

For the control unit 295799 the most common cause is stored crash data, even if no airbag was triggered in the accident. Added to this are aged components, cold solder joints, moisture, corrosion at plug connectors and voltage spikes.

A standard diagnostic tool cannot erase this crash data. Airbag24 erases it during the repair.

Further causes in detail:

• aged electronic components
• cold solder joints
• moisture and corrosion at plug connectors
• voltage spikes, for example from a weak battery or a jump start

How can you tell that the 295799 is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently on the 295799. In addition, a fault message appears in the instrument cluster, the diagnostic tool finds no connection to the control unit, and the fault memory cannot be cleared.

Such a fault concerns safety: airbags and seatbelt pretensioners may then be unable to deploy in an emergency.

The light shows the fault as soon as the system detects it. That is why the indicator should not be ignored but checked promptly.
