Airbag control unit with part number 1481000080

What is the function of the airbag control unit 1481000080?

The airbag control unit 1481000080 from Autoliv is the central control module for the restraint system in the Peugeot 806. Its task is to process data from the connected crash sensors and, in the event of an accident, to deploy the airbags and seatbelt pretensioners precisely and reliably.

As an original ECU (Electronic Control Unit) module, this component serves as the brain of the passive safety system. It continuously monitors all relevant components and ensures they function correctly in an emergency.

The control unit is specifically designed for the Peugeot 806 I model years 1994 to 2002 (including the facelift). A failure in this safety-critical component inevitably leads to the complete malfunction of the airbag system.

Why does the control unit 1481000080 fail?

The most common cause of failure for the control unit 1481000080 is the storage of crash data after an accident, which blocks further functionality. Other defects arise from purely electronic malfunctions in internal components, as well as from moisture ingress, leading to corrosion and short circuits.

After an accident in which the airbags have deployed, the control unit stores so‑called crash data. For safety reasons, this information locks the module and prevents reuse until the data is professionally reset.

Electronic failures are also a frequent cause. Defects in individual components on the circuit board can disrupt internal logic, resulting in persistent error codes or total communication failure.

A further vulnerability is moisture. Water ingress—such as from vehicle leaks—can cause corrosion on the circuit board, leading to temporary or permanent malfunctions.

How do you recognize a defect in the control unit 1481000080?

A defect in the control unit 1481000080 primarily manifests as a permanently illuminated or flashing airbag warning light on the instrument cluster. Often, communication with the control unit via an OBD diagnostic tool is no longer possible, complicating troubleshooting and strongly indicating an internal fault.

The most obvious sign is the activated airbag warning lamp. After starting the vehicle, it not only lights up briefly but remains on continuously or begins to flash, clearly signaling a system malfunction.

If a workshop cannot establish a connection to the airbag control unit through the diagnostic port, this is a strong indication of a serious electronic fault within the module itself. In such cases, the device no longer responds to queries.

Rarely, unusual electrical symptoms may also appear, such as a blinking engine check light or unexpectedly illuminated speedometer lighting, both attributable to malfunctions caused by the defective airbag control unit.

In which vehicles is the control unit 1481000080 installed?

The airbag control unit with part number 1481000080 was developed by Autoliv specifically for the Peugeot 806. At Airbag24, this safety‑critical module is professionally and reliably refurbished for the entire first generation of the model, including facelift variants.

Repair of this control unit is available for the following Peugeot models and series:

Peugeot 806 I (First Generation, model years 1994–1998)

Peugeot 806 I Facelift (Model refresh, model years 1998–2002)

How is the repair of the control unit 1481000080 carried out?

At Airbag24, the repair of the control unit 1481000080 follows a proven process. Upon receipt, the unit undergoes a comprehensive diagnosis to identify the root cause of the fault. Defective components are then replaced, crash data is erased, and a final functional test is performed to ensure quality.

The first step after sending the unit to Airbag24 is always a detailed incoming inspection. During this phase, the fault memory is read, and the device is examined for visible damage, such as moisture-related issues.

The actual refurbishment involves, depending on the defect, replacing faulty electronic components on the circuit board and securely erasing all stored crash data.

Following repair, each control unit is tested on a specialized test bench to confirm full functionality. Airbag24 provides 2 years' statutory liability for defects on all repairs.
