Airbag control unit with part number 9673393680

What does the airbag control unit 9673393680 do?

The airbag control unit 9673393680 is the central control unit of the restraint system (SRS) for Citroën and Peugeot. It evaluates the signals from the crash sensors and decides in a fraction of a second during an accident which airbags and seatbelt pretensioners are triggered.

The unit monitors the system throughout operation. If it detects a fault, it reports this via the airbag warning light in the instrument cluster.

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

Why does the control unit 9673393680 fail?

The most common cause is crash data stored after an accident, even if no airbag was deployed. A normal diagnostic tool cannot erase it, but Airbag24 deletes it during the repair. Other causes are aged electronic components, cold solder joints, moisture and corrosion on plug connections, and voltage spikes, for example from a weak battery or jump-starting.

The crash data remain stored in the unit, and an ordinary diagnostic tool cannot reach them. This applies regardless of how severe the accident was and whether an airbag was deployed.

The other causes develop gradually. Components age, solder joints give way and moisture damages the plug connections. Voltage spikes arise when the battery weakens or the vehicle is started with external power.

How can you tell that the 9673393680 is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently, an error message appears in the instrument cluster, the diagnostic tool finds no connection to the control unit, and the fault memory cannot be cleared. In an emergency, the airbags and seatbelt pretensioners may then not deploy.

The warning light is the clearest sign, because it reports the fault immediately. Even an intermittent display is a hint that you should not ignore.

Please have the finding checked promptly, before you continue to use the vehicle more than necessary.

(a) Compare the part number on the label of the removed unit with this page. This only shows that it is the correct unit, nothing more. (b) Have the fault memory read out beforehand, because only the result shows whether the control unit is defective or whether a connector or a cable is the cause.
