Airbag control unit with part number 9664908180

What does the airbag control unit 9664908180 do?

The 9664908180 processes the signals from the crash sensors and decides in an accident, within milliseconds, which airbags and seatbelt pretensioners are triggered. It is part of the restraint system (SRS) of Peugeot and shows faults via the airbag warning light.

While driving, the control unit monitors the connected components without a break, i.e. sensors, triggers and their wiring.

If an accident occurs, the unit writes crash data and locks itself.

Why does the control unit 9664908180 fail?

The 9664908180 fails mainly because of stored crash data that remain after an accident, even without an airbag having fired. Ordinary diagnostic tools cannot remove them; Airbag24 removes them during the repair.

The fact that no airbag ignited does not rule out storage. The unit logs the event, and the entries then appear as faults.

Also possible are aged electronic components, cold solder joints, and moisture and corrosion at plug connectors. Voltage spikes, for example from a weak battery or when connecting to a jump start, can also affect the unit.

Whether any of these causes applies can only be determined by a targeted test.

How can you tell that the 9664908180 is defective?

The airbag warning light in the instrument cluster lights up permanently or only intermittently and thus indicates a defect. In addition, an error message in the instrument cluster, a disrupted connection to the diagnostic tool and a fault memory that cannot be erased may occur. In this state, airbags and seatbelt pretensioners may not be able to trigger in an emergency.

If the warning light is on, you should act promptly rather than hoping that the display will clear by itself.

Such signs cannot reliably be interpreted from the outside; a check is therefore the right way.
