Airbag control unit with part number 619906500

What is the function of the airbag control unit 619906500?

The airbag control unit with part number 619906500 is the central control module for the occupant protection system in the Peugeot 308 SW III. It continuously analyzes data from crash sensors and, within milliseconds, determines whether to deploy airbags and seatbelt pretensioners, ensuring optimal protection for vehicle occupants in the event of a collision.

This control unit is a safety-critical component that coordinates communication among the various elements of the restraint system. It ensures that, depending on the severity and type of accident, the appropriate safety features are activated.

The electronics are designed to work with systems from various suppliers such as Bosch, Delphi, or Continental, and therefore must be precisely matched to the vehicle’s configuration to operate flawlessly.

Why does the control unit 619906500 fail?

A failure of the control unit 619906500 is usually caused by stored crash data following an accident, even if no airbags were deployed. Other common causes include internal electronic faults due to overvoltage, water damage, or the failure of individual components, leading to communication errors or persistent fault messages.

The most frequent reason for repair is the storage of crash events. Even minor rear-end impacts or malfunctions in the seatbelt pretensioner system can cause the control unit to lock itself for safety reasons and log an internal error.

Electronic malfunctions are another major cause. Overvoltage in the vehicle’s electrical system, moisture ingress, or age-related wear of memory chips and processors can result in total failure or sporadic malfunctions.

Internal faults signaled by error codes such as 65535 or 93F9 indicate a defect in the internal hardware. Repairs focus on diagnosing and replacing the affected electronic components.

This fault pattern also appears in related part numbers like 9665100080, 610714900, 9674291480, 619763800, and 9673383480, which are installed in similar vehicle platforms.

How do you recognize a defect in the 619906500?

A defect in the airbag control unit 619906500 almost always manifests as a permanently illuminated or flashing SRS airbag warning light on the instrument cluster. Often, the control unit can no longer be accessed by diagnostic equipment, or specific error codes such as “internal error” or “crash data stored” are read out.

The clearest indication is the activated airbag warning light. It signals that the entire restraint system is disabled and will no longer provide protective functions in the event of a crash, posing a significant safety risk.

Another clear symptom is the lack of communication. If the workshop cannot access the airbag control unit using its diagnostic tool, this points to a severe internal hardware defect.

The fault memory may also contain specific messages, including issues related to insufficient supply voltage, CAN bus communication problems, or excessive resistance in the airbag or seatbelt pretensioner ignition circuits.

In which vehicles is the control unit 619906500 installed?

The airbag control unit 619906500 is primarily installed in vehicles of the Stellantis Group, especially in the third-generation Peugeot 308. It is found in the Peugeot 308 SW III from model year 2021 onward, as well as in the upcoming facelift model and related variants such as the Peugeot 308 III (P51).

How does the repair of the 619906500 proceed at Airbag24?

Repair at Airbag24 begins with a professional analysis of the submitted control unit. Stored crash data is then cleared, defective electronic components are replaced, and the unit is reset. Following a final functional test, you receive a fully operational component backed by a 12-month warranty.

Before removing the control unit, a thorough diagnosis performed by a qualified workshop is essential. This ensures that the root cause of the fault lies in the control unit itself and not in the wiring or sensors. Please attach your diagnostic report to your shipment.

Upon receipt at Airbag24, our technicians conduct a systematic incoming inspection. They read out the fault memory and examine the electronic components for damage caused by overvoltage or other external influences.

The actual repair involves precisely erasing the crash data at the chip level and replacing any defective components. The unit is fully restored to the condition of a brand-new part.

Finally, each repaired control unit undergoes a comprehensive functional test. This ensures that it processes all signals correctly and once again guarantees 100% vehicle safety. We provide a 12-month warranty on every repair.

Is repairing the 619906500 worthwhile?

Repairing the airbag control unit 619906500 is an economically and technically sensible alternative to the expensive purchase of a new unit. You save significantly compared to a new part, which often costs over 500 euros, and receive a fully tested, fully functional component that restores vehicle safety.

The biggest advantage is the substantial cost savings. While a new control unit from the manufacturer typically comes with high expenses, repair offers a much more affordable solution without compromising safety.

A repaired control unit is technically equivalent to a new one. All safety‑related functions are restored and thoroughly tested, ensuring the full protective performance of the airbag system.

With over 20 years of experience and more than 20,000 repairs completed, our technicians possess the expertise needed to reliably fix even complex faults in this control unit.

If, in rare cases, a repair proves impossible, there is often the option to acquire a remanufactured replacement unit. In every situation, we find a timely and safe solution for your vehicle.
