Airbag control unit with part number 9802736280

What does the airbag control unit 9802736280 do?

The airbag control unit 9802736280 is responsible for the restraint system (SRS) in Peugeot. It analyses the signals from the crash sensors, decides in an accident whether airbags and seatbelt pretensioners are triggered, and monitors the system continuously.

Faults are stored and reported via the airbag warning light in the instrument cluster. This way the driver can see whether the restraint system is working properly.

After an accident the control unit writes crash data and locks itself.

Why does the control unit 9802736280 fail?

Stored crash data is the most common cause of failure, even if no airbag was triggered in the accident. A normal diagnostic tool cannot remove it, and this is precisely what leads to the fault message.

During the repair by Airbag24 the crash data is erased. This is the decisive step to make the unit ready for use again.

Ageing electronic components, cold solder joints, and moisture and corrosion on the plug connections can also lead to failure. Voltage spikes, for example from a weak battery or a jump start, also belong to these causes.

How can you tell that the 9802736280 is defective?

The airbag warning light in the instrument cluster stays on permanently or intermittently when there is a defect in the 9802736280. A fault message, a diagnostic tool without connection and a fault memory that cannot be cleared additionally indicate this.

Such signs must be taken seriously, because in an emergency the airbags and seatbelt pretensioners may fail to trigger. Do not wait for the problem to resolve itself.

A fault memory that cannot be cleared is a clear indication of the control unit.
