Alfa Romeo Junior airbag control unit repair⁽¹⁾

What should be noted about Alfa Romeo Junior airbag control units?

The airbag control unit of the Alfa Romeo Junior evaluates the crash sensors, triggers the airbags, monitors the system and reports faults via the airbag warning light. After an accident, it stores crash data and locks itself.

The airbag system is safety-relevant. Work on it should therefore be left to a specialist workshop.

At Airbag24, the control unit is checked and repaired in our workshop in Berlin. This includes erasing the crash data and checking for faults. Which repair is needed is only determined by this check.

Which Alfa Romeo Junior generations are there?

The Alfa Romeo Junior has been built since 2024. One series is listed for this model so far: series 966, whose production run is still ongoing.

The series designation 966 identifies the Junior from model year 2024 onwards. Whether a vehicle belongs to this series can be checked using the model year and the vehicle identification number (VIN).

No other series are listed for this model so far. Assignment should therefore always be based on model year and vehicle data.

• 966 (since 2024, production still ongoing) – the current series of the Alfa Romeo Junior

How do I identify my Alfa Romeo Junior airbag control unit?

The part number on the label of the control unit determines the exact version. Together with the model year and equipment of the vehicle, it is an important reference point for the repair.

When you make your enquiry, please state the model year and equipment of your Alfa Romeo Junior so that the assignment is unambiguous.

Examples of fault codes from the airbag system are:

• B1813: supply circuit of the integrated airbag diagnostic module
• B1932: driver airbag: squib circuit open (open circuit)
• B1933: passenger airbag: squib circuit open (open circuit)
• B1887: driver airbag: squib circuit short to ground

A fault code alone does not prove that the control unit is defective. It shows that the system has detected a fault; the cause is only established by the check in the workshop.

What airbag equipment does the Alfa Romeo Junior have?

According to the manufacturer, the Alfa Romeo Junior has six airbags: two front airbags for driver and front passenger, two side curtain airbags and two side airbags in the seats. The exact equipment depends on market and trim level.

The airbag control unit coordinates these airbags in the event of an impact, which makes it central to occupant protection. If the control unit is defective, the function of the entire system can be impaired, and the airbag warning light indicates this.

The repair works as follows: have the fault memory read, the battery disconnected and the control unit removed by a specialist workshop. You then create a repair order online and send the control unit by parcel to Airbag24.

Processing usually takes 3–4 working days (checking, repairing, testing). The repaired control unit is returned with all vehicle data and is ready for use immediately after refitting — no coding or programming is required.
