Airbag control unit with part number 50550298

What does the airbag control unit 50550298 do?

The airbag control unit 50550298 coordinates the restraint system in the Alfa Romeo vehicle. It evaluates crash sensors and decides in a crash which airbags and seatbelt pretensioners are triggered.

The manufacturer's part number Bosch 0285013983 is additionally printed on the housing. The unit monitors the system continuously and shows faults via the airbag warning light.

After a crash it stores crash data and locks itself.

Why does the control unit 50550298 fail?

The most common causes are crash data stored after an accident, even if no airbag has deployed. A normal diagnostic tool cannot erase them, and Airbag24 removes them during the repair. In addition there are aged electronics, cold solder joints, moisture at plug connectors and voltage spikes.

Crash data can therefore be at the start of a fault, even if nothing was triggered in the accident. That makes it a point to check during every diagnosis.

The other causes can develop over years, through ageing, moisture or fluctuations in the on-board voltage.

How can you tell that the 50550298 is defective?

The airbag warning light is on constantly or intermittently, an error message appears in the instrument cluster, the diagnostic tool cannot reach the control unit, and the fault memory cannot be cleared.

If these signs occur, airbags and seatbelt pretensioners may fail to deploy in an emergency. You should therefore have the vehicle checked promptly.
