Airbag control unit with part number 9666343480

What does the airbag control unit 9666343480 do?

Within the restraint system (SRS) of Peugeot, the airbag control unit 9666343480 controls the processes. It checks the signals from the crash sensors, decides in an accident which airbags and seatbelt pretensioners trigger, and monitors the system permanently. Faults are reported via the airbag warning light.

After an accident it stores crash data and locks itself. In addition, the housing carries the number Bosch 0285010525.

The results of the monitoring feed directly into the decision on triggering.

Why does the control unit 9666343480 fail?

The most common cause: crash data stored after an accident, even if no airbag has triggered. Added to this are aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

An ordinary diagnostic tool cannot remove the crash data. Airbag24 deletes it during the repair.

The other causes at a glance:

• electronic components that age over time
• solder joints that have gone cold
• moisture and corrosion at plug connections
• voltage spikes, for example from a weak battery or jump start

How can you tell that the 9666343480 is defective?

A defect shows when the airbag warning light stays on permanently or intermittently, when an error message is displayed in the instrument cluster, when the diagnostic tool does not reach the control unit, or when the fault memory cannot be cleared. In an emergency, airbags and seatbelt pretensioners could then possibly not trigger.

The airbag warning light in the instrument cluster is the most noticeable sign, because it informs the driver directly. An error message in the instrument cluster is added, and together the two are a clear indication.

A diagnostic tool that makes no contact with the control unit, or a fault memory that cannot be cleared, also belongs to these signs.
