Airbag control unit with part number 9807276780

What does the airbag control unit 9807276780 do?

The airbag control unit 9807276780 is the central control unit of the restraint system (SRS) in the Peugeot. It uses the crash sensors to detect whether an impact has occurred and, in an emergency, decides whether airbags and seatbelt pretensioners are triggered. At the same time, it monitors the system and reports faults via the airbag warning light.

The evaluation takes place within fractions of a second. The decisive factors are the measured deceleration and how it develops over time.

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

Why does the control unit 9807276780 fail?

The most common cause is crash data stored after an accident, even if no airbag was deployed; a standard diagnostic tool cannot erase it. Other causes are:

• aged electronic components
• cold solder joints
• moisture and corrosion at plug connections
• voltage spikes, for example from a weak battery or a jump start

The crash data remains stored until it is erased during repair. The other points can also cause a fault without an accident.

How can you tell that the 9807276780 is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently. In addition, there is an error message in the instrument cluster, the diagnostic tool has no connection to the control unit, and the fault memory cannot be cleared. In this state, airbags and seatbelt pretensioners may not deploy in an emergency.

Take the light seriously. It goes out after the ignition is switched on if the system finds no fault. If it stays on, the fault should be checked.
