Airbag control unit with part number 50573184

What does the airbag control unit 50573184 do?

At Alfa Romeo, the airbag control unit 50573184 forms the control centre of the restraint system (SRS). It reads the signals from the crash sensors and decides in an accident within milliseconds on triggering airbags and seatbelt pretensioners.

The unit monitors the system continuously and passes faults on via the airbag warning light. The manufacturer's number Bosch 0285020613 is additionally printed on the housing.

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

Why does the control unit 50573184 fail?

The most common cause on the 50573184 is stored crash data from an accident, even if no airbag has deployed; a normal diagnostic tool does not erase it. Other causes are aged components, cold solder joints, humidity and corrosion in plug connectors, and voltage spikes.

Stored crash data remains in the unit until it is specifically removed. Airbag24 removes it during the repair.

Aged electronics and cold solder joints show up mainly under load. Humidity and corrosion attack the contacts, while voltage spikes, for example from a weak battery or jump-starting, additionally stress the components.

How can you tell that the 50573184 is defective?

The airbag warning light in the instrument cluster lights up continuously or intermittently, an error message appears, the diagnostic tool does not find the control unit, or the fault memory cannot be cleared. In that case, airbags and seatbelt pretensioners may not deploy in an emergency.

If the warning light comes on when the ignition is switched on and does not go out afterwards, that is a clear signal, and a check is advisable. Even intermittent lighting justifies a readout.

A fault memory that cannot be cleared is a further indication of a problem in the control unit itself or of crash data in the memory.
