Airbag control unit with part number 9812713280

What does the airbag control unit 9812713280 do?

The airbag control unit 9812713280 controls the restraint system (SRS) of Peugeot. It evaluates the signals from the crash sensors, decides in an accident on the triggering of airbags and seatbelt pretensioners, and monitors the system continuously.

The manufacturer's number Bosch 0285012921 is additionally printed on the housing. When comparing the removed unit it is a further reference point, though it says nothing about the condition.

The monitoring covers sensors, wiring and output stages and reports faults via the airbag warning light. After an accident the control unit stores crash data and locks itself.

Why does the control unit 9812713280 fail?

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

Crash data remains in the unit, even if the vehicle drives inconspicuously again after the accident. The warning light can therefore stay on although nothing can be seen outside any more.

The other causes act without an accident: components age, solder joints can be damaged, moisture attacks contacts, and voltage spikes from the on-board network strain the electronics.

How can you tell that the 9812713280 is defective?

Signs of a defect are an airbag warning light that lights up constantly or intermittently, a fault message in the instrument cluster, no connection between the diagnostic tool and the control unit, and a fault memory that cannot be cleared.

• Airbag warning light is on constantly
• Airbag warning light is on intermittently
• Fault message in the instrument cluster
• Diagnostic tool cannot reach the control unit

In an emergency the airbags and seatbelt pretensioners may fail to deploy if the control unit is defective.

The display shows that something is wrong, but not what exactly. Only reading out the fault memory provides that.
