Airbag control unit with part number 1358991080

What is the function of Airbag Control Unit 1358991080?

The airbag control unit with part number 1358991080 is the central control module of the occupant restraint system (SRS) in vehicles such as the Peugeot Boxer III and similar models from Fiat and Citroën. It processes data from crash sensors and determines whether to deploy airbags and seatbelt pretensioners.

As the heart of passive vehicle safety, this control unit continuously monitors all connected components, including front and side airbags, seatbelt pretensioners, seatbelt buckle switches, and various acceleration and pressure sensors distributed throughout the vehicle. Its primary task is to activate the necessary restraint systems within milliseconds in the event of a crash, providing optimal protection for occupants.

This unit is specifically designed for the vehicle platform used in the Peugeot Boxer III (from 2006), Fiat Ducato, and Citroën Jumper. It ensures seamless communication among all safety‑related components and logs the system status. Any detected anomaly triggers the airbag warning light on the instrument panel to alert the driver.

Why does control unit 1358991080 fail?

The most common cause of failure for control unit 1358991080 is stored crash data following an accident, which permanently locks the device. Additionally, internal hardware defects in electronic components, as well as external factors like undervoltage or moisture, can lead to total failure.

Even after a minor rear-end collision where seatbelt pretensioners or airbags have deployed, the control unit irrevocably writes so‑called crash data into its internal memory. This lockout is a safety feature and cannot be cleared by standard workshop diagnostics. The unit reports a persistent fault and must be repaired or replaced.

Internal electronic malfunctions are another frequent cause. Defective components on the circuit board—such as microprocessors or capacitors—can result in internal errors (e.g., error codes B0100 or B0102) or complete loss of communication. Such damage may arise from aging or electrical disturbances in the vehicle’s onboard network.

External factors, such as a faulty battery or alternator, can damage sensitive electronics in the control unit through undervoltage. Moisture—caused, for example, by spilled beverages near the center console or under the seats—can also lead to corrosion and short circuits on the circuit board. Often, control units from the same family, such as 1370978080, 1342894080, 1357312080, or 1367537080, exhibit identical fault patterns.

How do you recognize a defect in control unit 1358991080?

A defect in control unit 1358991080 primarily manifests as a persistently illuminated airbag warning light on the instrument cluster. Additional symptoms include loss of communication with diagnostic equipment or specific error codes indicating an internal malfunction of the control unit.

The clearest sign is the airbag warning lamp that fails to turn off after starting the vehicle. This indicates a serious fault in the restraint system, meaning airbags will not deploy in the event of a crash. Such a vehicle would fail the mandatory technical inspection (TÜV).

Another clear symptom occurs when a professional diagnostic tool (e.g., from Gutmann or Bosch) cannot establish communication with the airbag control unit. The unit no longer responds to requests, making precise fault analysis impossible and often pointing to total hardware failure.

Specific error codes are frequently logged in the fault memory, directly referencing the control unit. These include codes such as B0100/B0102 for internal control unit faults, B1001/B101C for issues with the seatbelt buckle switch—attributable to faulty signal processing within the device—or the absence of a chassis number entry.

In which vehicles is control unit 1358991080 installed?

The airbag control unit 1358991080 is primarily installed in the third-generation Peugeot Boxer. Due to the platform’s design compatibility, it is also used in compatible models such as the Fiat Ducato and Citroën Jumper from the same production periods.

At Airbag24, we repair control units with part number 1358991080 for the following specific model series:

Peugeot: Boxer III (2006–2011), Boxer III First Facelift (2011–2014), Boxer III Second Facelift (2014–2024), and Boxer III Third Facelift (from 2023 onward).

Its use in sister models from Fiat and Citroën is common, as these vehicles share the Sevel platform and many technical components—including safety electronics.

What are the benefits of repairing 1358991080?

Repairing the original control unit offers substantial cost savings of up to 70% compared to purchasing a new part. Additionally, there’s no need for time-consuming re‑coding, and the repair is a sustainable solution backed by a 12‑month warranty.

The financial advantage is significant. While a new control unit can cost up to 800 euros according to the manufacturer, professional refurbishment is far more economical. It restores full functionality without straining your budget.

A repaired original part is always plug-and-play. Since it’s the vehicle’s own control unit, all vehicle‑specific data—such as the VIN and equipment configuration—remain intact. By contrast, replacing it with a new or used part often requires costly and time‑consuming coding at an authorized workshop.

Repairing also contributes to sustainability. Rather than discarding a complex electronic component, it undergoes expert refurbishment, conserving valuable resources and reducing e‑waste. Each repair comes with a 12‑month warranty.

How does the repair process work at Airbag24?

The repair process begins with the proper removal of the control unit and its shipment to Airbag24. At our workshop, we perform a thorough analysis, erase crash data, and replace any defective components. Following a final functional test, the unit is returned ready for installation.

Before removal, it’s crucial to have a diagnosis performed at a specialized workshop. This ensures that the fault lies in the control unit itself, rather than in peripheral components such as the seat occupancy sensor or wiring harness. Please include a diagnostic report with your shipment.

Upon receipt of the control unit at Airbag24, our technicians conduct an initial inspection. The unit is then opened to examine the circuit board and pinpoint the root cause of the defect. The core of the repair involves erasing crash data from the memory chip and replacing any potentially faulty electronic components.

We use only professional repair methods. Employing simulators or resistors to bypass faults is life‑threatening, results in loss of operating approval, and is strictly prohibited. After repair, the control unit undergoes a comprehensive functional test.

Once testing is successful, the unit is sealed and shipped back to the customer. Upon reinstallation in the vehicle, the workshop simply needs to clear the system’s fault memory to complete the process.

What shipping options are available at Airbag24?

To ensure smooth processing, Airbag24 offers flexible shipping options. You can either send your defective control unit yourself or arrange convenient UPS pickup. For returns, free standard UPS shipping is included, along with faster express options.

For sending your unit to us, you have two convenient choices: free self‑shipping, where you take the package to the post office yourself, or scheduling UPS pickup from a location of your choice—such as your workshop or home.

When returning the repaired control unit, standard UPS shipping—with a typical delivery time of 1–3 business days—is already included at no extra charge. For urgent cases, we offer expedited UPS Express shipping for an additional fee, ensuring delivery within 1–2 business days.

Both standard and express shipping can be combined with cash‑on‑delivery service upon request. Alternatively, you may choose to pick up the repaired control unit in person at our workshop at any time.
