Alfa Romeo 4C 960 airbag control unit repair

What is an Alfa Romeo 4C 960 airbag control unit?

The Alfa Romeo 4C 960 airbag control unit is the central safety unit of the passive restraint system, which specifically activates all airbags and seatbelt pretensioners in the event of a collision. It continuously monitors all relevant sensors, processes data in real time, and stores important crash information to provide optimal occupant protection.

This highly integrated module is crucial for the functionality of the entire airbag system. It is robustly constructed to withstand extreme conditions such as vibrations and temperature fluctuations. The control unit meets the highest safety standards and is designed for reliable operation in the Alfa Romeo 4C sports car.

Why is the Alfa Romeo 4C 960 airbag control unit defective?

The Alfa Romeo 4C 960 airbag control unit may be defective because crash data was permanently stored after an accident, or internal memory and communication errors occur. This causes the system to no longer function correctly and the airbag warning light to illuminate, making repair necessary.

Common causes of failure include internal electronic defects, which can be caused by aging or electrical surges. Another reason is the storage of crash information, which requires a reset of the control unit. Without this repair, the airbag system remains inactive. A professional Alfa Romeo 4C 960 airbag control unit repair fixes these problems.

Common error codes for Alfa Romeo 4C 960 airbag control unit repair

During Alfa Romeo 4C 960 airbag control unit repairs, specific error codes often occur that indicate internal problems or stored crash data, rather than external sensors. These codes signal the need for diagnosis and repair of the control unit itself to restore safety.

• **B1000** → Communication faulty → Internal defect or faulty connection to the control unit.
• **B1001** → Crash data saved → Accident event was detected and must be reset.
• **B1020** → Internal memory error → Problem with the EEPROM or the internal memory module of the control unit.
• **B1201** → Internal self-test error → The control unit could not pass its own functional test.
• **B1234** → EEPROM error → Corruption or damage of the data stored in the EEPROM.

What part numbers are available for the Alfa Romeo 4C 960 airbag control unit repair?

The most common known OEM part number for the Alfa Romeo 4C airbag control unit is 50531518, directly from the manufacturer Alfa Romeo. When repairing the Alfa Romeo 4C 960 airbag control unit, it is crucial to check this number carefully and, if necessary, verify other specific numbers through official channels to ensure compatibility.
