Airbag control unit with part number 9673787180

What does the airbag control unit 9673787180 do?

The airbag control unit 9673787180 controls the restraint systems (SRS) for Citroën. It analyses the sensor signals, decides in an accident within milliseconds whether airbags and seatbelt pretensioners are triggered, and monitors the system continuously. It shows faults via the airbag warning light.

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

Why does the control unit 9673787180 fail?

The control unit 9673787180 most often fails because of stored crash data, even if no airbag was triggered. Further causes are aged electronic components, cold solder joints, and moisture and corrosion on plug connections. Voltage spikes, for example from a weak battery or jump-starting, can also cause a failure.

Crash data cannot be deleted with an ordinary diagnostic tool. Airbag24 deletes it during the repair.

The other causes are related to ageing, poor contacts and electrical loads.

How can you tell that the 9673787180 is defective?

You can recognise a defect on the 9673787180 by the airbag warning light in the instrument cluster, which stays on permanently or intermittently. Added to this are an error message in the instrument cluster, a missing connection to the diagnostic tool, and a fault memory that cannot be cleared.

While the fault exists, airbags and seatbelt pretensioners may possibly fail to trigger in an emergency. Therefore take the warning seriously and have it checked in good time.
