Airbag control unit with part number 1613695480

What is the function of the airbag control unit 1613695480?

The airbag control unit 1613695480 is the central control module for the passive safety system (Supplemental Restraint System, SRS) in the Citroën Nemo I. It processes data from the acceleration sensors in real time to ensure precise and rapid deployment of airbags and seatbelt pretensioners in the event of a collision.

As the “brain” of the restraint system, this module continuously monitors all connected components, from impact sensors to individual airbag modules, ensuring flawless operation when needed.

A failure in this control unit inevitably disables the entire airbag system. This is indicated to the driver by a permanently illuminated or flashing SRS warning light on the instrument panel, posing a significant safety risk that requires immediate diagnosis at a specialized workshop.

Why does the control unit 1613695480 fail?

The most common cause of failure for the control unit 1613695480 is stored crash data following an accident, which locks the system as a safety precaution. Other reasons include internal electronic faults triggered by overvoltage, water ingress, or component aging, as well as issues with external wiring.

After a collision, the unit irrevocably stores so‑called crash data. This lockout is a manufacturer‑imposed safety feature that necessitates a system check. The control unit must be reset by a specialist to restore full functionality.

Internal electronic damage is also a frequent source of failure. Error codes such as 65535, 93F9, or B1111 often point to internal malfunctions caused by defective microprocessors, memory chips, or solder joints. Causes may include overvoltage, moisture, or simply material fatigue.

The fault does not always lie within the control unit itself. Problems like broken wires, corroded connectors, or disturbances on the CAN bus can disrupt communication with the control unit and produce similar symptoms. Additionally, insufficient supply voltage or improper repair attempts can lead to malfunctions.

How do you recognize a defect in the control unit 1613695480?

A defect in the control unit 1613695480 primarily manifests as a permanently lit or flashing airbag warning light (SRS lamp) on the dashboard. Another clear indication is when the control unit becomes unreachable via a diagnostic tool, signaling a complete loss of communication.

The most obvious sign is the active SRS indicator light after starting the engine. It signals a critical fault in the restraint system and fails to extinguish after a few seconds as expected.

In the workshop, the defect often shows up as a lack of communication. When a technician attempts to read the fault memory using a diagnostic device, the control unit does not respond, making detailed fault analysis via the OBD port impossible.

The most severe consequence is the complete deactivation of all airbags and seatbelt pretensioners. In the event of an accident, the vehicle no longer provides protection through the passive safety system, dramatically increasing the risk of injury.

In which vehicles is the control unit 1613695480 installed?

The airbag control unit with part number 1613695480 is specifically designed for the Citroën Nemo I, produced between 2007 and 2015. Due to the shared platform, its technology is closely related to the Peugeot Bipper and Fiat Fiorino models from the same period.

At Airbag24, we repair the control unit 1613695480 for the following model:

Citroën Nemo I (model years 2007–2015)

How does the repair of the 1613695480 proceed at Airbag24?

Professional repair of the control unit 1613695480 includes electronic analysis at the component level, safe deletion of stored crash data, and replacement of defective parts. After restoration, the module undergoes a comprehensive functional test to ensure full safety and reliability.

Before removal, a workshop should read out the fault memory to confirm that the issue truly lies within the control unit. For removal, it is absolutely essential to disconnect the vehicle battery for at least 10 minutes to prevent unintended airbag deployment.

Upon submission to Airbag24, a detailed diagnosis of the circuit board follows. Our technicians analyze the hardware, erase stored crash data, and replace faulty electronic components such as processors, memory chips, or capacitors. Defective solder joints are professionally reworked.

Subsequently, each repaired control unit undergoes an end-of-line test on a specialized test bench that simulates real‑world vehicle conditions. Only when all functions are operating flawlessly and the internal fault memory is cleared is the unit approved for return shipment. We provide 2 years' statutory liability for defects on every repair.

Is it worth repairing control unit 1613695480?

Yes, repairing part number 1613695480 is an economically and technically sensible alternative to the costly purchase of a new unit. A brand‑new component can cost up to €400, whereas repair offers substantial savings while restoring the device to its original condition—without requiring re‑coding.

The greatest advantage is the significant cost reduction compared to a new OEM part. You receive a fully functional, tested component at a fraction of the price of a new unit.

Since the original control unit is repaired, all vehicle‑specific data and coding remain intact. After repair, the unit can be easily reinstalled (plug‑and‑play) and is ready to use immediately, eliminating the need for time‑consuming and expensive reprogramming at an authorized service center.

Repair also represents a sustainable solution: it helps avoid electronic waste and conserves valuable resources by professionally refurbishing an existing component. With 2 years' statutory liability for defects on the repair, you take no risks.
