Airbag control unit with part number 1481002080

What is the function of Airbag Control Unit 1481002080?

The airbag control unit with part number 1481002080 is the central control module for the occupant protection system in the Peugeot Expert III. As an original Peugeot (PSA) control unit, it processes signals from crash sensors and coordinates the deployment of airbags and seatbelt pretensioners in the event of a collision, ensuring the safety of vehicle occupants.

This ECU (Electronic Control Unit) serves as the brain of the entire passive safety system. It continuously monitors all connected components, including various airbags (such as knee, passenger, or seat‑mounted airbags), seatbelt pretensioners, and their associated crash sensors. Only when all system parameters are correct will the airbag warning light remain off after the vehicle is started.

In the event of a collision, the 1481002080 control unit determines within milliseconds which restraint systems need to be deployed to provide optimal protection for occupants. Following such an incident, it permanently stores the crash data, making further use impossible without professional repair.

What defects occur in 1481002080?

The most common defect of the 1481002080 control unit is the storage of crash data after an accident, which cannot be cleared via OBD diagnostics and locks the system. Other failures include internal hardware malfunctions in components such as sensors or capacitors, as well as complete communication failure with diagnostic tools, often caused by moisture damage.

After a crash, the control unit internally locks itself to prevent improper reuse. This lock cannot be removed using conventional workshop testers and requires electronic‑level repair.

Another typical cause of failure is hardware defects on the circuit board, which may involve faulty components like capacitors or issues with the internal memory. Such faults can render the control unit unable to perform its functions correctly, even if no accident has occurred.

Besides accidents, causes of these defects also include moisture ingress or pre-existing damage resulting from improper repair attempts. Similar fault patterns can also appear in related part numbers, such as 9817062880.

How do you recognize a defect in the 1481002080 control unit?

A defect in the 1481002080 control unit primarily manifests as a persistently illuminated airbag warning light in the instrument cluster that does not turn off after the engine starts. Additionally, the control unit can no longer be read via the OBD2 interface, making diagnosis impossible. Error messages remain even after airbag components have already been replaced.

The most obvious symptom is the constantly lit airbag warning light. It may illuminate immediately upon ignition or remain on after a brief self‑diagnostic phase of about 30 seconds, signaling a critical system error.

Another clear indication is when the control unit becomes unreachable for diagnostic tools. The workshop then cannot establish a connection via the OBD2 interface to read fault codes or inspect the system.

If the fault memory contains entries that persist despite replacing the relevant components—such as airbags, seatbelt pretensioners, or crash sensors—the cause almost certainly lies within the control unit itself.

In which vehicles is part number 1481002080 installed?

The airbag control unit with part number 1481002080 is specifically used in vehicles manufactured by the PSA Group. At Airbag24, this control unit is primarily repaired for the third‑generation Peugeot Expert and its facelift models. Similar control units may also be used in identical vehicles or models such as the Peugeot Boxer.

At Airbag24, we repair part number 1481002080 for the following models:

Peugeot Expert III (model years 2016–2024)

Peugeot Expert III Facelift (from model year 2024 onward)

Compatibility has been verified for these models. A detailed fault description and accompanying test reports from a specialized workshop help ensure precise and efficient repairs.

What are the benefits of repairing 1481002080?

Repairing the 1481002080 airbag control unit is a cost‑effective alternative to purchasing a new one. Compared to a new part, which can cost up to 800 euros according to the manufacturer, repairs save significantly. Moreover, post‑repair, re‑programming of the vehicle is unnecessary. The repair restores full functionality and comes with 2 years' statutory liability for defects.

The greatest advantage is the substantial cost savings compared to buying a new component. Repair offers a budget‑friendly solution without compromising safety or performance.

Since the original, vehicle-specific control unit is refurbished, all coding and configurations are preserved. Time-consuming programming or re-learning, often required with a new part, is unnecessary. The repaired unit can be reinstalled via plug-and-play.

How does the repair process work at Airbag24?

At Airbag24, the professional repair of the control unit 1481002080 includes a detailed incoming inspection to analyze stored fault codes. Subsequently, crash data is erased at the chip level, and defective electronic components such as sensors or capacitors are replaced. After restoring the factory configuration, a final functional test is performed. We provide 2 years' statutory liability for defects on the completed repair.

Once the removed control unit arrives at Airbag24, technicians conduct a comprehensive diagnosis to identify the exact cause of the fault. This involves reading stored crash data as well as inspecting the hardware components.

In the next step, the stored crash data is cleared using specialized tools, and the control unit is reset to its factory settings. If any electronic components are defective, they are professionally replaced.

Upon completion of the repair, the control unit undergoes a thorough functional test. Only after all tests have been successfully passed is the unit approved for return shipment.
