Airbag control unit with part number 9805261380

What does the airbag control unit 9805261380 do?

The airbag control unit 9805261380 is the central control unit of the restraint system (SRS) for Peugeot. It evaluates the crash sensors, decides in an accident on airbags and seatbelt pretensioners, and monitors the system continuously. After an accident it stores crash data and locks itself.

The unit shows faults via the airbag warning light in the instrument cluster.

The supplier number Bosch 0285011760 is also printed on the housing.

Why does the control unit 9805261380 fail?

The most common cause with the 9805261380 is crash data from an accident, even if no airbag has deployed; ageing components, cold solder joints, moisture at plug connections and voltage spikes are also possible.

Crash data are entries in the memory and not damage to the component.

The other causes concern the electronics themselves: ageing components, cold solder joints on the circuit board, and moisture and corrosion at plug connections.

Voltage spikes, for example from a weak battery or jump-starting, can likewise lead to failures.

How can you tell that the 9805261380 is defective?

A fault on the 9805261380 shows as the airbag warning light staying on permanently or intermittently, and as a fault message in the instrument cluster. The diagnostic tool finds no connection to the control unit, and the fault memory cannot be cleared. In an emergency, airbags and seatbelt pretensioners may then fail to deploy.

The warning light is the most visible sign; the message in the instrument cluster supplements it.

If the light comes on, a prompt check of the system is worthwhile. A single sign shows the fault; the readout shows the cause.
