Airbag control unit with part number 0285014893

What does the airbag control unit 0285014893 do?

The airbag control unit 0285014893 is the central control unit of the restraint system (SRS) for Alfa Romeo. It evaluates the crash sensors, determines in the event of an accident which airbags and seatbelt pretensioners are triggered, and monitors the system permanently. After an accident, it stores crash data and locks itself.

The unit makes the triggering decision within milliseconds so that the protective systems respond in time. For this, the entire chain of sensors, evaluation and actuators must function at all times.

During operation, the unit checks its connections and circuits. If it finds a fault, it stores it in memory and reports it to the driver.

Why does the control unit 0285014893 fail?

Stored crash data is the most common cause of a failure on the 0285014893, even if no airbag deployed in the accident; an ordinary diagnostic tool cannot delete it. Other causes are aged electronic components, cold solder joints, moisture and corrosion at plug connections, as well as voltage spikes, such as from a weak battery or jump-starting.

Let us begin with the crash data: the unit stores it after the accident, and it remains in memory until it is deleted. Airbag24 takes over the deletion during the repair.

The other causes affect the electronics themselves. Components age over time, solder joints can develop poor contacts, and moisture acts on the metal parts at the plug connections.

How can you tell that the 0285014893 is defective?

The airbag warning light in the instrument cluster is on permanently or intermittently when a fault is present on the 0285014893. In addition, there are fault messages in the instrument cluster, a lack of connection from the diagnostic tool to the control unit, and a fault memory that cannot be cleared.

If you notice these signs, you must expect that airbags and seatbelt pretensioners may possibly not trigger in an emergency. The light is no minor matter, because it shows the state of the system exactly when it matters.

The diagnostic tool does not find the control unit in this case, and the fault memory remains. Both point to having the unit checked thoroughly.

Which vehicles is the 0285014893 fitted in?

The control unit 0285014893 is fitted in these vehicles: Alfa Romeo Stelvio 949 Facelift (from 2023) and 949 (2017-2023); Alfa Romeo Giulia 952 (2016-2023) and 952 Facelift (from 2023).

The list shows the vehicles on record for this part number.

• Alfa Romeo Stelvio 949 Facelift (from 2023)
• Alfa Romeo Stelvio 949 (2017-2023)
• Alfa Romeo Giulia 952 (2016-2023)

The label comparison only ensures that the unit matches this page, and nothing beyond that. Have the fault memory read out in advance, because only the log shows whether the control unit is defective or whether a plug or cable is the cause.

For the same vehicles, we also repair control units with the part numbers 285013327, 285014905, 50534060, 50534061, 50543842, 50543843.

How does the repair of the 0285014893 work?

First read the fault memory and enclose the log. Then disconnect the battery, only then remove the control unit, and create a repair order online. Airbag24 generally needs 3–4 working days to process the unit.

After removal, pack the unit well, enclose the printed order and send it in.

Airbag24 examines the unit on the test bench, replaces defective components and then deletes the stored crash data. A function test follows, after which the unit is returned.

Our repairs come with 2 years' statutory liability for defects.

The repaired control unit comes back with all vehicle data and is ready for use as soon as it is refitted — no coding or programming is required.

How does the control unit 0285014893 get to Airbag24?

You send the control unit 0285014893 to Airbag24 as a parcel or book a UPS collection for an extra charge. After the repair, it comes back to you by UPS. The printed repair order goes into the parcel, and the unit must be packed shockproof.

Make sure the unit is fixed in the box so that it cannot move on the way.
