Airbag control unit with part number 9673383480

What is the function of the airbag control unit 9673383480?

The airbag control unit with part number 9673383480 is the central control module of the passive safety system in the Peugeot 308 SW III. It continuously monitors signals from crash sensors to ensure that, in the event of an accident, the airbags and seatbelt pretensioners are deployed precisely and within seconds.

As the “brain” of the restraint system, this component constantly analyzes data from acceleration and pressure sensors throughout the vehicle. It ensures all airbags are ready for deployment, logs the system’s status, and communicates with other control units via the CAN bus.

The proper functioning of this control unit is critical for occupant protection. Any internal fault or blockage will disable the entire airbag system, indicated by a warning light on the dashboard.

Why does the airbag control unit 9673383480 fail?

The most common causes of failure for control unit 9673383480 are stored crash data following an accident, which locks the device, as well as internal electronic defects in components. Moisture damage or thermal overload can also lead to complete failure.

After a collision, the control unit stores non-erasable crash data. This is a manufacturer‑imposed safety measure that locks the system, preventing further use without professional repair. Repair is essential to restore functionality.

Electronic defects are another widespread cause. Internal error codes such as 93F9, 65535, CAN errors, or specific side‑sensor faults indicate defective microprocessors, memory chips (EEPROM), or other components on the circuit board. These hardware issues cannot be resolved simply by clearing the fault memory.

The control unit is also installed in vehicles with alternative part numbers, including 9665100080, 610714900, 9674291480, 619763800, and 619906500. Based on experience, these variants exhibit identical fault patterns and can be repaired in the same way.

How do you recognize a defect in control unit 9673383480?

A defect in control unit 9673383480 primarily manifests as a permanently illuminated or flashing SRS airbag warning light on the instrument panel. Additionally, communication with the diagnostic tool may be impossible, or non‑erasable internal error codes may appear.

The most obvious symptom is the active airbag warning light. It clearly indicates to the driver that the restraint system is inoperative and that airbags would not deploy in the event of an accident. Immediate inspection is therefore mandatory.

Another clear sign is a complete loss of communication. If a workshop attempts to read the fault memory, the diagnostic tool receives no response from the control unit—this points to a severe internal hardware failure.

If entries such as “internal error,” “control unit defective,” or specific codes like 93F9 or 65535 remain in the fault memory and cannot be cleared, this directly indicates a defect within the device itself, rather than in external components like sensors or wiring.

In which vehicles is control unit 9673383480 used?

The airbag control unit 9673383480 is specifically designed for the Peugeot 308 III series. It is primarily used in the Peugeot 308 SW III from model year 2021 onward, as well as in the subsequent facelifted version, and is compatible with various alternative part numbers.

How does the repair of control unit 9673383480 work at Airbag24?

Repair at Airbag24 is a straightforward process: After removal, you send us the defective control unit. Our technicians perform a precise diagnosis, reset crash data, replace faulty components, and restore full functionality, backed by a 12‑month warranty.

Once the control unit arrives at Airbag24, it undergoes a systematic incoming inspection. The reported fault is verified, and the hardware on the circuit board is analyzed to pinpoint the exact source of the issue.

This is followed by professional component‑level repair. Depending on the defect, stored crash data is professionally erased, or faulty electronic components such as processors or memory chips are replaced with new, high‑quality parts. The unit is then restored to factory condition.

Before being returned, every repaired control unit undergoes a comprehensive functional test on the test bench. This ensures that the device communicates flawlessly once again and performs all safety‑critical functions just as well as a brand‑new unit. We provide a 12‑month warranty on every repair performed.
