Airbag control unit with part number 9803380180

What does the airbag control unit 9803380180 do?

The airbag control unit 9803380180 is the central processing unit of the SRS in Peugeot. It processes the measurements from the crash sensors, determines within a few milliseconds which airbags and seatbelt pretensioners are triggered, and reports faults via the airbag warning light. After an accident, it stores crash data and locks itself.

Besides the part number, the number Bosch 0285011404 can also be found on the housing.

During operation, the unit monitors sensors and wiring continuously, so that deviations are detected early.

Why does the control unit 9803380180 fail?

The most common cause is stored crash data, even without an airbag deployment. Other possible causes include aged components, moisture at plug connectors and voltage spikes.

Crash data remains stored if no airbag has deployed, and a normal diagnostic tool cannot erase it.

The other causes concern the electronics themselves. Aged components, moisture and corrosion on the contacts, as well as brief voltage spikes, for example from a weak battery, can cause malfunctions.

How can you tell that the 9803380180 is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently, an error message appears on the display, the diagnostic tool cannot find the control unit, or the fault memory cannot be cleared. In this case, airbags and seatbelt pretensioners may not be able to deploy in an emergency.

The warning light shows the defect directly as soon as the system detects it. That is why it is the most important indication in the vehicle.

If the warning light is on, have the fault memory read out promptly so that it becomes clear which part of the system is affected.
