Airbag control unit with part number 13583431

What does the airbag control unit 13583431 do?

The airbag control unit 13583431 acts as the switching centre of the SRS in Opel. It processes the crash sensor system, decides in an accident within milliseconds on airbags and seatbelt pretensioners, and monitors the entire system continuously. After an accident it stores crash data and locks itself.

In normal operation it continuously checks its surroundings: wiring, sensors and trigger stages. If it finds a deviation, it stores it and displays it.

Why does the control unit 13583431 fail?

The most common cause is crash data from an accident, which is stored even when no airbag has deployed and which cannot be erased with a normal diagnostic tool. In addition there are ageing electronic components, cold solder joints, moisture and corrosion on plug connections, and voltage spikes such as those from a weak battery or jump-starting.

After an accident the unit creates crash data. This remains until Airbag24 erases it as part of the repair.

The other causes concern the electronics themselves: components age, solder joints can be cold, and moisture together with corrosion affects plug connections. Voltage spikes additionally stress the electronics, for example with a weak battery or jump-starting.

How can you tell that the 13583431 is defective?

A defect first shows itself through the airbag warning light, which lights up permanently or intermittently, and through an error message in the instrument cluster. In addition, no connection between the diagnostic tool and the control unit is established, or the fault memory remains after clearing. In an emergency, airbags and seatbelt pretensioners may then fail to trigger.

The light reflects the state of the restraint system for as long as the unit is switched on.

A fault that only occurs intermittently remains a fault. A check of the fault memory is worthwhile even then.

Two points belong before removal. You compare the part number on the label with this page; this only confirms the right unit. Having the fault memory read out, on the other hand, shows whether the control unit is defective or whether a connector or cable is a possible cause.

For the same vehicles, we also repair control units with the part numbers 12848365, 13503645, 13505596, 13505598, 13578320, 13578322.

How does the repair of the 13583431 work?

At the start comes the read-out of the fault memory, whose log is enclosed with the unit; then you disconnect the battery and remove the control unit. Afterwards you create a repair order online and send the unit in well packed. Processing at Airbag24 usually takes 3–4 working days.

At Airbag24, the unit is first examined on the test bench. The team repairs defective components, then crash data is erased and a functional test is carried out.

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 13583431 get to Airbag24?

The unit reaches Airbag24 as a parcel, or you book a UPS collection for an extra charge. After the repair, Airbag24 sends it back by UPS.

The printed repair order is in the parcel, and the unit itself is packed shock-proof.
