Airbag control unit with part number 1353558080

What is the function of Airbag Control Unit 1353558080?

The Airbag Control Unit 1353558080 is the central control module for the occupant protection system in the Citroën Nemo I and related Peugeot models. It processes signals from crash sensors to precisely deploy airbags and seatbelt pretensioners in the event of a collision, thereby protecting vehicle occupants.

As the “brain” of the passive safety system, this unit continuously monitors all connected components, including the various airbags (driver, passenger, side), seatbelt pretensioners, and their associated acceleration and pressure sensors. In the event of a collision, the control unit determines within milliseconds which restraint systems need to be activated.

The part number 1353558080 is specifically designed for this vehicle platform and ensures the proper functioning of all safety‑related components. Therefore, flawless operation is essential for vehicle safety.

Why does Control Unit 1353558080 fail?

Typical faults of Control Unit 1353558080 include the persistent illumination of the airbag warning light, communication issues with diagnostic tools, or stored crash data after an accident. Common causes are internal electronic malfunctions or damage due to overvoltage, such as water ingress.

A frequent cause of apparent malfunction is stored crash data. After a collision, the control unit locks access and reports an internal error to prevent re‑activation. This data must be professionally erased to restore full functionality.

Another failure mode is an internal fault within the control unit itself, often caused by defective electronic components on the circuit board. Such hardware defects frequently result in loss of communication with the control unit.

External factors like overvoltage or moisture can also lead to damage. For example, water damage inside the vehicle can permanently impair the sensitive electronics of the control unit if not addressed promptly.

How do you recognize a faulty Airbag Control Unit 1353558080?

A defect in Control Unit 1353558080 primarily manifests as the airbag warning light remaining constantly illuminated on the instrument cluster. Additionally, the unit often cannot be read by a diagnostic tool due to disrupted communication. Following an accident, the device is typically locked.

The most obvious sign is the red airbag warning light, which fails to extinguish after starting the vehicle—indicating a serious system fault that requires immediate inspection.

In the workshop, the fault often becomes evident through complete loss of communication: the diagnostic tool cannot establish a connection with the airbag control unit, making OBD‑based fault diagnosis impossible. Error codes such as “internal control unit error” are also clear indicators.

How does the repair of Control Unit 1353558080 proceed?

Repair at Airbag24 begins with a detailed analysis of the submitted control unit. Stored crash data is then erased, electronic fault sources are rectified, and the unit is restored to its original factory condition. You receive a 12‑month warranty on the completed repair.

Once the removed control unit arrives at Airbag24, it undergoes an initial incoming inspection. Using advanced diagnostic technology, our technicians identify the exact cause of the fault—whether it’s a software issue stemming from crash data or a hardware defect.

The core of the repair involves eliminating the root cause of the problem. This includes professionally erasing crash data, repairing electronics at the component level, and restoring the original factory settings. As a result, the control unit regains full operational capability after repair.

Finally, each repaired control unit undergoes a comprehensive functional test to ensure all faults have been resolved. Only after a successful test is the unit approved for return shipment.

Is It Worth Repairing the Airbag Control Unit?

Repairing the unit is significantly more cost-effective than purchasing a new one, which often costs around 400 euros. You can save up to 70% of the expense. Moreover, the repaired unit is ready for immediate installation (plug-and-play), as it is restored to factory settings and requires no re-coding.

The biggest advantage is the substantial cost savings. While a new control unit from the manufacturer comes with high expenses, repair offers an affordable yet reliable alternative.

Since the original control unit is repaired and reset to its factory condition, there’s no need for time-consuming and costly reprogramming or coding at the workshop. The device can simply be reinstalled and will function right away.
