Airbag control unit with part number 9665250180

What does the airbag control unit 9665250180 do?

The airbag control unit 9665250180 is the central control unit of the restraint system (SRS) for Citroën and Peugeot. It evaluates the signals from the crash sensors and, in an accident within milliseconds, decides which airbags and seatbelt pretensioners are triggered. It indicates faults via the airbag warning light.

The unit monitors the system continuously. After an accident it stores crash data and locks itself.

Why does the control unit 9665250180 fail?

The most common cause is stored crash data after an accident, even if no airbag has deployed. Further causes are ageing electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

A normal diagnostic tool leaves the crash data in place, so it cannot be erased with one. Airbag24 erases the crash data during the repair.

The other causes involve ageing and wear of the electronics, poor contact in connections, and electrical loads.

How can you tell that the 9665250180 is defective?

A defect shows itself through the airbag warning light, through fault messages, or through a diagnostic tool without connection to control unit 9665250180. A fault memory that cannot be erased is also a sign.

• airbag warning light in the instrument cluster lights up permanently or intermittently
• fault message in the instrument cluster
• diagnostic tool receives no connection to the control unit
• fault memory cannot be erased

If any of these signs is present, airbags and seatbelt pretensioners may not be able to deploy in an emergency. The light reports the fault, so have it checked promptly.
