Airbag control unit with part number 96667324XT

What is the function of the airbag control unit 96667324XT?

The airbag control unit 96667324XT is the central control module for the occupant protection system (SRS) in the Citroën C3 II. It continuously monitors the sensors, evaluates crash data in the event of an accident, and activates the airbags and seatbelt pretensioners as needed to ensure the safety of vehicle occupants.

As the SRS Control Unit (Supplemental Restraint System), this control unit plays a crucial role in the vehicle’s passive safety. It collects and processes information from acceleration and pressure sensors to determine the severity and nature of a collision and precisely triggers the appropriate restraint systems.

Why does the control unit 96667324XT fail?

A failure of the control unit 96667324XT is most commonly caused by stored crash data following an accident, which locks the unit. Other causes include electrical faults such as broken wiring, defective connectors, overvoltage, or insufficient supply voltage—often indicated by error code 65535.

After a collision, crash data is permanently stored in the control unit’s memory. This safety mechanism “locks” the unit, preventing further use until the data is professionally erased and the unit is reset. Repairing the unit is often the cost-effective alternative to replacing it with a new one.

Even without an accident, electrical issues can lead to failure. Defects on the internal circuit board—such as damaged capacitors or chips—as well as problems with the power supply are typical sources of failure. These hardware defects prevent the airbag system from functioning correctly.

How do you recognize a fault in the airbag control unit?

A faulty control unit 96667324XT primarily manifests as a constantly illuminated or flashing SRS warning light on the instrument panel. Additional signs include the inability to communicate with a diagnostic tool, the vehicle’s clock ceasing to function, or complete system failure when exposed to heat.

The most obvious warning sign is the airbag indicator light. If it remains lit continuously, the system indicates a critical fault, disabling the airbags—a serious safety risk. In the event of a crash, the vehicle would no longer deploy its restraint systems.

Another clear symptom is a lack of communication. When a specialist workshop attempts to read the fault memory but the control unit fails to respond, this points to an internal defect within the control unit.

Rarer, yet still indicative of a fault, are accompanying symptoms such as a non-functioning clock or complete system failure at elevated temperatures inside the vehicle.

In which vehicles is 96667324XT installed?

The airbag control unit with part number 96667324XT was specifically developed for vehicles of the Citroën brand. It is mainly used in the second-generation Citroën C3 and its facelift model, making it particularly relevant for owners of these series.

At Airbag24, we repair the control unit 96667324XT for the following specific models. Compatibility has been confirmed for these series:

Citroën: C3 II (model years 2009–2013) and C3 II Facelift (model years 2013–2017).

What are the benefits of repairing 96667324XT?

Repairing the control unit 96667324XT offers significant cost savings—often exceeding 50% compared to purchasing a new unit, which can cost over €500. Additionally, the original vehicle coding is preserved, simplifying the replacement process and reducing environmental impact through the reuse of electronic components.

The financial advantage is the key factor. While a new control unit from the manufacturer is typically very expensive, professional repair provides an economically sensible solution without compromising safety.

Since the original control unit is repaired, the factory configuration and coding remain fully intact. This means that after reinstallation, extensive re-learning or programming of the vehicle is usually unnecessary—the repaired unit functions just like the original.

How is the control unit 96667324XT professionally repaired?

During professional repair, the control unit 96667324XT undergoes a precise diagnosis to pinpoint the source of the fault. Stored crash data is then erased, and defective electronic components—such as chips or capacitors—are carefully replaced. Following a final functional test, the unit is fully operational again.

After submission to Airbag24, the repair follows a proven procedure. Technicians read the fault memory and analyze the circuit board to identify the exact defect—whether it’s a locked memory chip due to crash data or a hardware issue with a component.

The core of the repair lies in addressing the root cause. Using specialized software, crash data is safely erased to reset the control unit. Defective components are replaced with high-quality spare parts, and damaged wiring or solder joints are repaired.

Finally, the repaired control unit is thoroughly tested for full functionality to ensure it communicates flawlessly with the vehicle again and the SRS warning light goes off. We provide a 12-month warranty on every repair.
