Airbag control unit with part number 5441 1218.964

What is the function of Airbag Control Unit 5441 1218.964?

The airbag control unit with part number 5441 1218.964 serves as the central control module for the passive safety system in Alfa Romeo GTV 916 and Spider 916 models. Its primary task is to process sensor data to deploy airbags and seatbelt pretensioners at precisely the right moment during a collision.

As the brain of the restraint system, this control unit continuously monitors all connected components, such as crash sensors, airbag modules, and seatbelt pretensioners. It processes their signals in real time to assess the severity of a collision.

In the event of an accident, the unit makes the critical decision on which restraint systems need to be activated. This precise control is essential for protecting vehicle occupants and ensuring the reliable operation of the entire airbag system.

Why does Airbag Control Unit 5441 1218.964 fail?

The most common cause of failure is the storage of crash data after an accident, which the control unit locks for safety reasons. Other causes include internal electronic malfunctions leading to communication issues, or memory errors that cannot be cleared.

After an airbag deployment, so‑called crash data is stored in the control unit’s memory. These data lock the device’s functionality and cannot be removed using standard diagnostic tools. Professional repair is required to erase this data and reset the unit.

Another frequent reason is internal electronic defects. This may involve failures of processors, memory chips, or other components on the circuit board, resulting in total malfunction or communication problems with the diagnostic tester.

The system can also be identified by alternative part numbers such as 60664500, 11316236, 152642080, 55704, and 55705. These variants are technically related and exhibit similar fault patterns.

How do you recognize a defect in Control Unit 5441 1218.964?

A defective control unit primarily manifests as the airbag warning light constantly illuminated in the instrument cluster. Additionally, error codes stored in the fault memory cannot be cleared, or the unit becomes completely inaccessible to diagnostic tools, preventing further troubleshooting.

The most obvious symptom is a persistently lit or intermittently flashing airbag indicator light. This signals a fault in the restraint system, often originating within the control unit itself.

During workshop diagnostics, it is frequently observed that fault codes remain stored in the memory and cannot be erased. This points to a persistent internal fault that cannot be resolved through simple resetting.

In severe cases, communication between the diagnostic tool and the airbag control unit breaks down entirely. The unit fails to respond to queries, making accurate fault analysis impossible and usually indicating a serious internal defect.

In which models is Control Unit 5441 1218.964 installed?

How is Control Unit 5441 1218.964 professionally repaired?

Professional repair at Airbag24 begins with an initial inspection of the unit. Depending on the nature of the defect, stored crash data is erased, reprogramming (neuro‑programming) is performed, or faulty electronic components are replaced. Following a final functional test, the unit is returned with 2 years' statutory liability for defects.

Before removal, a diagnosis by a specialized workshop is recommended to confirm that the fault originates from the control unit itself rather than external components like sensors or wiring.

Upon submission to Airbag24, a detailed technical analysis is conducted at the component level. Specialized procedures such as neuro‑programming address software and memory errors, while erasing crash data restores full functionality after an accident.

If physical damage is present, defective electronic components are expertly replaced. Each repair concludes with a comprehensive functional test to ensure the unit operates as well as new. You receive 2 years' statutory liability for defects on the completed repair.
