Airbag control unit with part number 13517439

What does the airbag control unit 13517439 do?

The airbag control unit 13517439 is the central control unit of the restraint system (SRS) in Opel. It evaluates the signals from the crash sensors and decides within milliseconds in an accident which airbags and seatbelt pretensioners are triggered. At the same time, it monitors the system continuously.

If the unit detects a fault, it shows it via the airbag warning light in the instrument cluster. This light is the visible sign to you that something is wrong in the restraint system.

After an accident, the control unit stores crash data and locks itself.

Why does the control unit 13517439 fail?

For the control unit 13517439, the most common cause is crash data stored after an accident, even if no airbag was triggered. Other causes include ageing electronic components, cold solder joints, moisture and corrosion on plug connections, and voltage spikes.

Crash data remain stored in the unit after the event. A normal diagnostic tool cannot erase them. During the repair, Airbag24 erases them.

The other causes develop over time. Electronics age, solder joints can remain cold, and moisture attacks plug connections. Voltage spikes, for example from a weak battery or a jump-start, add further strain to the circuits.

How can you tell that the 13517439 is defective?

A defect in the 13517439 shows itself mainly through the airbag warning light in the instrument cluster, which lights up permanently or intermittently. Further indications are an error message and a lack of connection to the diagnostic tool.

The signs in detail:

• The airbag warning light lights up permanently or intermittently.
• An error message appears in the instrument cluster.
• The diagnostic tool cannot establish a connection to the control unit.
• The fault memory cannot be erased.

In an emergency, the airbags and seatbelt pretensioners may then fail to trigger. Therefore do not ignore the warning light.
