Airbag control unit with part number 9673787080

What does the airbag control unit 9673787080 do?

The airbag control unit 9673787080 controls the restraint system in Peugeot vehicles. It evaluates the crash sensors, determines within milliseconds in an accident which airbags and seatbelt pretensioners are triggered, and monitors the entire system. After an accident it stores crash data and locks itself.

The unit recognises faults through its ongoing self-test. It indicates any fault it detects via the airbag warning light in the instrument cluster.

Why does the control unit 9673787080 fail?

The most common cause is crash data that remains stored after an accident, even if no airbag has fired. Aged electronic components, cold solder joints, moisture or corrosion on plug connections and voltage peaks are also possible.

The crash data is held in the memory of the control unit. An ordinary diagnostic tool can read it but cannot erase it. Airbag24 erases it during the repair.

The other triggers lie in the electronics. Components age, solder joints can stay cold, moisture and corrosion damage plug contacts, and voltage peaks, for example from a weak battery or a jump-start, load the circuit.

How can you tell that the 9673787080 is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently. In addition, a fault message appears in the instrument cluster, the diagnostic tool cannot find the control unit 9673787080, and the fault memory cannot be cleared.

The warning light is an important signal, because through it the system indicates a fault. Even if the vehicle otherwise drives normally, it remains a clear signal.

As long as the fault exists, airbags and seatbelt pretensioners may fail to deploy in an emergency. Please have the fault checked promptly.
