Airbag control unit with part number 285580013R

What does the airbag control unit 285580013R do?

The control unit 285580013R belongs to the restraint system (SRS) at Renault and decides in a crash which airbags and seatbelt pretensioners are triggered. The signals needed for this come from the crash sensors, whose values it evaluates within milliseconds.

The device also monitors the system continuously. It indicates faults via the airbag warning light; after an accident it stores crash data and locks itself.

While driving, no one notices any of this as long as everything is in order.

Why does the control unit 285580013R fail?

Crash data stored in the device after an accident is the most common cause, even if no airbag has triggered; a standard diagnostic tool cannot remove it. Other possible causes are aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

Electronic components age, and over time solder joints can stay cold or contacts can weaken.

Moisture penetrates through plug connections and leads to corrosion that disrupts the current flow. Voltage spikes, for example from a weak battery or after a jump start, are a further cause of faults.

As part of the repair at Airbag24, crash data is removed.

How can you tell that the 285580013R is defective?

You can recognise a defect in the 285580013R from several signs that show up in the instrument cluster and in the behaviour of the diagnostic tool.

• Airbag warning light in the instrument cluster is on permanently
• Airbag warning light is on only intermittently
• Fault message in the instrument cluster
• Diagnostic tool finds no connection to the control unit
• Fault memory cannot be cleared

These signs mean that airbags and seatbelt pretensioners may not trigger in an emergency.

Whether the control unit itself is affected must be clarified by the read-out.

Which vehicles is the 285580013R fitted in?

The 285580013R is fitted in these vehicles: Renault Scénic III (2009-2016); Renault Grand Scénic III (2009-2016).

This overview shows the vehicles that belong to this number:

• Renault Scénic III (2009-2016)
• Renault Grand Scénic III (2009-2016)

Comparing the part number on the label of the removed device with this page shows whether it is the right device. Having the fault memory read out, on the other hand, shows whether the control unit is defective or whether a connector or a cable is the cause; this happens before removal.

For the same vehicles, we also repair control units with the part numbers 284100-22023, 285580008R, 285580012R, 285580014R, 285580045R, 285580053R.

How does the repair of the 285580013R work?

Processing at Airbag24 usually takes 3–4 working days. Beforehand, have the fault memory read out and enclose the log, then disconnect the battery and only then remove the control unit. Then create a repair order online and send the device in well packed.

At Airbag24 the device is examined on the test bench, defective components are repaired, crash data is deleted, and a function test completes the work. Your own device is then returned.

The time specification refers exclusively to the work in house, not to your steps or the shipping.

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 285580013R get to Airbag24?

You send the control unit 285580013R as a parcel to Airbag24 or book a UPS collection for an extra charge. After the repair it is returned to you by UPS.

The printed repair order goes into the parcel, and the device must be packed shockproof.
