Airbag control unit with part number 9676209280

What does the airbag control unit 9676209280 do?

The airbag control unit 9676209280 controls the restraint system (SRS) of Citroën. It reads the crash sensors and, in an accident, calculates within milliseconds which airbags and seatbelt pretensioners to trigger. It also checks the system continuously and reports faults via the airbag warning light.

The check runs in the background without any action from you.

After an accident, the unit stores crash data and locks itself.

Why does the control unit 9676209280 fail?

The most common cause on the 9676209280 is crash data stored after an accident, even if no airbag was triggered. A normal diagnostic tool cannot delete it.

Aged electronic components are also a possible cause, as are cold solder joints. Moisture and corrosion on plug connections belong here too, as do voltage spikes from a weak battery or a jump start.

That is why the fault memory is the right first step, because it shows which cause applies. Not every fault originates in the unit itself; plug connections are also a possibility.

How can you tell that the 9676209280 is defective?

A defect on the 9676209280 shows up as an airbag warning light in the instrument cluster that lights up permanently or intermittently, as error messages in the instrument cluster, as no connection to the diagnostic tool, or as a fault memory that cannot be cleared.

The warning light is the signal you are most likely to see. If it stays on or comes back, that is a reason to have the restraint system checked.

As long as the fault exists, airbags and seatbelt pretensioners may not trigger in an emergency. The warning light therefore shows the defect before a check establishes it.

For the same vehicles, we also repair control units with the part numbers 00006546T7, 618300400, 626181500, 9656888580, 9673657880, 98 038 323 80.

How does the repair of the 9676209280 work?

First have the fault memory read out and attach the log. Then disconnect the battery and only then remove the 9676209280. Next, create a repair order online and send in the well-packed unit.

Airbag24 checks the control unit on the test bench, replaces defective components and deletes stored crash data. A function test follows, after which your own unit goes back to you.

The order is mandatory for safety reasons, because the battery must be disconnected before removal.

Processing at Airbag24 usually takes 3–4 working days. This only refers to the work at Airbag24, not your preparation and not the shipping.

Our repairs come with 2 years' statutory liability for defects. The repaired control unit comes back with all vehicle data and is ready for use as soon as it is refitted — no coding or programming is required.
