Airbag control unit with part number 9654491280

What is the function of the airbag control unit 9654491280?

The airbag control unit with part number 9654491280 from Autoliv is the central control module for the passive safety system in the Peugeot 307 CC. It processes signals from crash sensors, deploys the front airbags in the event of a collision, and stores relevant crash data in its internal memory.

This specific component is primarily installed in first-generation Peugeot 307 CC models (model years 2001–2009), especially vehicles equipped with the NFU engine code (1.6 16V, 110 hp, Euro 4). The main task of the control unit is to monitor and manage the airbag system to ensure occupant safety in an emergency.

Why does the control unit 9654491280 fail?

Failures of the control unit 9654491280 often result from external factors such as water ingress, particularly in the spare‑tire well. Another major cause is the storage of crash data after an accident, which can lock the unit. Aging-related failures of electronic components also lead to malfunctions.

A common cause of failure is water damage. In the Peugeot 307 CC, the location in the spare‑tire well is especially susceptible to moisture penetration, leading to corrosion and short circuits on the circuit board. This can completely disrupt communication with the vehicle.

After a collision, the control unit stores crash data and locks itself for safety reasons. This lock often cannot be reset using standard diagnostic tools and requires specialized electronic repair, involving reprogramming the internal memory.

Software errors or coding issues may also occur, necessitating reprogramming by a specialist. This control unit is known under several other part numbers, including equivalents 9650109480 and 9652712380, as well as various manufacturer numbers from Autoliv (e.g., 603724900) or Siemens (e.g., 5WK42908).

How do you recognize a defect in the control unit 9654491280?

A defective airbag control unit 9654491280 typically manifests as a continuously or intermittently illuminated airbag warning light on the instrument cluster. Often, communication with the control unit via a diagnostic tool is no longer possible, complicating troubleshooting.

The most prominent sign is the active airbag warning light, indicating a fault in the restraint system and resulting in failure during the mandatory technical inspection (HU). The light may remain on constantly or flash at irregular intervals.

Another clear symptom is complete loss of communication: workshops can no longer access the control unit with their diagnostic equipment to read out error codes. The unit simply fails to respond to tester requests.

In some cases, error codes are stored that cannot be cleared. A typical example is a persistent error code for the driver’s airbag, which remains even after replacing the coil spring. This points to an internal defect within the control unit itself, rather than a peripheral component.

In which vehicles is the control unit 9654491280 installed?

The airbag control unit with part number 9654491280 is specifically designed for Peugeot models. At Airbag24, we primarily repair this unit for the first‑generation Peugeot 307 CC, covering both pre‑facelift and facelift versions.

Specifically, this control unit can be found in the following model series:

Peugeot: 307 CC I (model years 2001–2005) and 307 CC I Facelift (model years 2005–2009).

The component was specially used in models such as the Peugeot 307 CC Cabrio (Restyling 3B, e.g., model year 2005) and is responsible for the proper functioning of the front airbag system in these vehicles.

How is the control unit 9654491280 professionally repaired?

Repair of the control unit 9654491280 at Airbag24 is performed at the electronic level. After removal and shipment, the unit is analyzed to identify the root cause of the fault. Subsequently, stored crash data is erased, and the software is reprogrammed to restore full functionality.

As a first step, it is recommended to read out the vehicle’s fault memory while communication is still possible. Following removal, the control unit is securely packaged and sent to Airbag24 along with a repair form.

Our technicians conduct a thorough analysis. The repair focuses on the software level, including professional erasure of crash data, reprogramming of the memory, and restoration of communication with the vehicle. Replacement of the unit is usually not required.

After successful repair and final testing, the control unit is returned to you. It can then be reinstalled in your vehicle (plug-and-play). We provide a 12-month warranty on all repairs.

What are the benefits of a repair?

Repairing the airbag control unit 9654491280 is a cost-effective and sustainable alternative to purchasing a new one. You save significantly compared to a new part, which often costs between 750 and 800 euros. Additionally, the original vehicle coding is preserved, avoiding complications during installation.

A key advantage is the substantial cost savings. While a new control unit represents a significant investment, repair is considerably more affordable and restores full functionality.

Another benefit is maintaining the original vehicle configuration. A used control unit from another vehicle might require time-consuming re-coding. With a repair, the factory‑original programming remains intact, ensuring the unit is ready for immediate use after installation.

Furthermore, Airbag24 offers a 12-month warranty on the completed repair, providing you with added peace of mind. You’re choosing a proven, reliable solution.
