Airbag control unit with part number 1367506080

What is the function of the airbag control unit 1367506080?

The airbag control unit with part number 1367506080 is the central control module of the passive safety system in vehicles such as the Citroën Nemo I or Fiat models. Its primary task is to process sensor data to deploy airbags and seatbelt pretensioners in the event of a crash, while permanently storing this crash event in its internal memory.

As the “brain” of the restraint system, this module continuously evaluates signals from the vehicle’s acceleration and pressure sensors. If it detects a collision exceeding predefined thresholds, it sends ignition pulses to the corresponding airbags and seatbelt pretensioners within milliseconds.

A critical function of control unit 1367506080 is the permanent storage of crash data in its internal memory (EEPROM/Flash). After an accident, this data cannot be erased using conventional workshop diagnostic tools. For safety reasons, the system remains locked until professional repair is performed.

What defects occur in control unit 1367506080?

The most common reason for repairing control unit 1367506080 is permanently stored crash data following an accident, which locks the system. Other causes include internal electronic faults—such as issues with memory chips or the power supply—that can lead to total failure or communication problems.

The primary cause of failure is the storage of crash data. Even minor accidents, where only the seatbelt pretensioners have deployed (e.g., rear-end collisions), result in an irreversible error entry being logged in the control unit. This inevitably triggers the airbag warning light.

In addition to crash data, internal hardware failures may also occur. These include defects in electronic components like memory ICs, processors, or voltage regulators on the circuit board. Such faults generate internal error messages (e.g., “internal control unit error”) and prevent the entire airbag system from functioning correctly.

A severe defect manifests as complete loss of communication. In this case, the control unit becomes inaccessible via the diagnostic interface (OBD). Workshops are unable to read fault codes or communicate with the module, making precise fault analysis impossible.

How do you recognize a defect in control unit 1367506080?

A clear indication of a defect is the persistently illuminated airbag warning light (SRS lamp) on the dashboard. Additionally, the airbag fault cannot be cleared using a diagnostic tool. In many cases, an internal control unit error is reported, or communication with the module is entirely impossible.

The most obvious symptom is the constantly lit airbag warning light. It does not turn off after starting the vehicle, signaling a malfunction in the restraint system that results in a significant failing grade during the vehicle inspection.

Another typical sign is that the airbag fault stored in the error memory cannot be reset. After attempting to clear it, the error reappears immediately, as the underlying cause—whether a crash record or a hardware defect—remains unresolved.

During diagnostics at the workshop, error codes directly pointing to the control unit are retrieved, such as “airbag control unit defective” or specific codes for internal faults. This provides clear evidence that the problem lies within the control unit itself.

In which vehicles is control unit 1367506080 installed?

Control unit 1367506080 is typically used in small commercial vans and compact vans. Airbag24 repairs this component for specific models, including the first-generation Citroën Nemo and the Fiat Daily 35. Identical derivatives from Peugeot may also be equipped with this control unit.

At Airbag24, control unit 1367506080 is refurbished for the following vehicles and model series:

Citroën: Nemo I (model years 2007–2015)

Fiat: Daily 35

Additionally, this part number may also be installed in platform-compatible Peugeot vehicles built on the same technical basis as the Citroën Nemo.

What are the advantages of repair over replacement?

Repairing control unit 1367506080 offers substantial cost savings compared to purchasing a new unit. Since the original control unit remains in the vehicle and its configuration is preserved, time-consuming adaptation or coding procedures are unnecessary. This makes refurbishment a quick and economical solution.

The financial benefit is significant. Repair often costs only a fraction of the price of a new original control unit purchased from an authorized dealer, saving several hundred euros.

Another crucial point is preserving the original part. During a repair, the vehicle-specific configuration and coding are either retained or correctly restored to factory settings. By contrast, replacing it with a new or used part often requires time-consuming reprogramming at the workshop.

Moreover, repair offers a sustainable alternative. Rather than discarding a complex electronic component, it is professionally refurbished and can continue to perform its function reliably in the vehicle. All repairs also come with 2 years' statutory liability for defects.

How does the repair of control unit 1367506080 work?

At Airbag24, the removed control unit first undergoes an electronic input inspection. This is followed by professional repair, which includes erasing crash data and fixing internal hardware faults. A final functional test on the test bench ensures proper operation before the device is returned with 2 years' statutory liability for defects.

The process begins with the careful removal of the control unit from the vehicle, typically located in the center console area or beneath the center tunnel. For safety reasons, the vehicle battery must be disconnected beforehand. The unit is then securely packaged and shipped to Airbag24.

Upon receipt at our specialized facility, a comprehensive diagnosis is performed to pinpoint the exact fault. Specialized technicians read out the internal memory modules to locate crash data or analyze internal errors.

The electronic refurbishment involves precisely erasing and overwriting crash data using dedicated hardware and software. If a hardware defect is present, faulty components such as memory chips, drivers, or voltage regulators on the circuit board are replaced with new ones.

After repair, each control unit undergoes a final inspection. Here, we verify that the unit communicates flawlessly, no internal errors remain, and all functions have been fully restored. Only after this successful testing is the unit shipped back to the customer.
