Airbag control unit with part number 50548494

What does the airbag control unit 50548494 do?

The airbag control unit 50548494 is the central control unit of the restraint system (SRS) for Alfa Romeo. It evaluates the signals from the crash sensors, decides in an emergency whether airbags and seatbelt pretensioners are triggered, and monitors the system continuously.

The housing additionally carries the manufacturer number Bosch 0285013981. The unit checks sensors and output stages continuously and reports faults via the airbag warning light.

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

Why does the control unit 50548494 fail?

Stored crash data from an accident are the most common cause with the 50548494, even if no airbag has triggered; an ordinary diagnostic tool cannot erase them. Further causes in brief:

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

Crash data are not component damage but stored content. Airbag24 erases them during the repair.

Which of the other causes applies to your unit is shown by the check on the test bench.

How can you tell that the 50548494 is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently if the 50548494 has a defect. Fault messages in the instrument cluster, no contact from the diagnostic tool to the control unit and a fault memory that cannot be cleared come on top of this.

In an emergency, airbags and seatbelt pretensioners may not trigger in the event of a defect. The light should therefore be taken seriously and checked promptly.

The light only shows that something is wrong; the cause is established by the reading.
