Airbag control unit with part number 9673573880

What does the airbag control unit 9673573880 do?

The airbag control unit 9673573880 controls the restraint system in vehicles from Peugeot. It checks the signals from the crash sensors, decides in an accident within milliseconds whether airbags and seatbelt pretensioners are triggered, and monitors the system continuously. After an accident it locks itself.

It reports faults in the system via the airbag warning light in the instrument cluster. The evaluation takes into account the entire course of an impact.

After an accident, it also stores crash data in its own memory.

Why does the control unit 9673573880 fail?

The most common cause of a failure of the 9673573880 is crash data stored after an accident, even if no airbag was triggered. A normal diagnostic tool cannot erase it.

The crash data remains in the memory, even when the vehicle is long back on the road. In addition, aged electronic components, cold solder joints, and moisture and corrosion on plug connections play a role. Voltage spikes, for example from a weak battery or jump-starting, can also cause a failure.

Which of these causes is actually present can only be clarified by examining the unit.

How can you tell that the 9673573880 is defective?

A defect in the 9673573880 may show up through the airbag warning light, which stays on permanently or intermittently, through a fault message in the instrument cluster, or because the diagnostic tool does not establish a connection. In an emergency, the airbags and seatbelt pretensioners may then not deploy.

Pay particular attention to these signs:

• airbag warning light that stays on or keeps coming on
• fault message in the instrument cluster
• missing connection between the diagnostic tool and the control unit
• fault memory that cannot be emptied despite attempts to clear it

A single sign is an indication, but not yet proof. Only the read-out fault memory shows what the cause is.
