Airbag control unit with part number 01389373080

What does the airbag control unit 01389373080 do?

The airbag control unit 01389373080 is the central control unit of the restraint system for Fiat and Opel. It evaluates the signals from the crash sensors, decides within milliseconds in an accident on the triggering of airbags and seatbelt pretensioners, and monitors the system continuously. After an accident it stores crash data and locks itself.

The unit reports faults via the airbag warning light in the instrument cluster, so that the condition becomes visible on the dashboard.

The unit does its work in the background, without the driver noticing anything.

Why does the control unit 01389373080 fail?

The most common cause is crash data stored after an accident, even if no airbag has deployed. A normal diagnostic tool cannot erase it. Other causes with the 01389373080 are aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

Aged components lose reliability over time, while cold solder joints connect only intermittently.

Voltage spikes arise, for example, when the battery is weak or a jump start is connected; moisture, in turn, attacks plug connections.

How can you tell that the 01389373080 is defective?

On the 01389373080, the airbag warning light in the instrument cluster lights up permanently or intermittently, a fault message appears in the instrument cluster, the diagnostic tool gets no connection to the control unit, or the fault memory cannot be cleared. Then airbags and seatbelt pretensioners may possibly not trigger in an emergency.

The warning light is the direct indication from the vehicle and shows the fault as soon as the unit detects it.

An interrupted contact with the diagnostic tool may also lie in the plug or the cable, not necessarily in the control unit.
