Airbag control unit with part number 50548732

What does the airbag control unit 50548732 do?

The control unit 50548732 is the central control unit of the restraint system (SRS) of Alfa Romeo. It evaluates the signals of the crash sensors, decides within milliseconds in a crash which airbags and seatbelt pretensioners are triggered, and monitors the system continuously.

Faults in the system are reported by the unit via the airbag warning light in the instrument cluster. The housing also carries the manufacturer number Bosch 0285013999.

After an accident it stores crash data and locks itself afterwards.

Why does the control unit 50548732 fail?

The most common cause is crash data stored after an accident, even where no airbag has deployed; a standard diagnostic tool cannot erase it. Ageing components, cold solder joints, moisture and corrosion, and voltage spikes are further factors.

Crash data arises in the accident and remains in the memory. Airbag24 erases it during the repair.

The other causes are rather gradual. Electronic components age, solder joints can go cold, and moisture attacks the contacts.

Voltage spikes, for example from a weak battery or a jump start, additionally stress the electronics.

How can you tell that the 50548732 is defective?

The airbag warning light in the instrument cluster lights up continuously or intermittently, an error message appears, the diagnostic tool cannot reach the control unit, or the fault memory cannot be erased.

The light is the most explicit indication the vehicle gives. If it comes on, have the system checked promptly.

In an emergency, airbags and seatbelt pretensioners may fail to trigger as long as the defect persists.
