Airbag control unit with part number 13379528

What does the airbag control unit 13379528 do?

The airbag control unit 13379528 coordinates the restraint system (SRS) of Opel. It evaluates the signals of the crash sensors, decides within milliseconds in a crash which airbags and seatbelt pretensioners are triggered, and monitors the entire system continuously. If it detects a fault, it displays it via the airbag warning light; after a crash it stores crash data and locks itself.

The control unit works in the background as soon as the ignition is switched on. The triggering decision is made within a few milliseconds, and for this all sensor signals must converge in the unit.

The crash data is created in the unit itself. A diagnostic tool can read it out, but cannot remove it.

Why does the control unit 13379528 fail?

Most often the cause lies in crash data stored after an accident, even if no airbag has been triggered; normal diagnostic tools cannot erase it. Other causes include aged electronics, cold solder joints, moisture and corrosion at plug connectors, and voltage peaks in the on-board electrical system.

Stored crash data remains in the unit, even when you connect the diagnostic tool. Reading it out displays the entries but does not remove them, so a simple reset does not help.

Further causes at a glance:

• aged components on the circuit board
• cold solder joints
• moisture and corrosion at plug connectors
• voltage peaks, for example with a weak battery or a jump start

How can you tell that the 13379528 is defective?

A defect shows itself through an airbag warning light in the instrument cluster that lights up permanently or intermittently, through a fault message in the instrument cluster, through a lack of connection to the diagnostic tool, or through a fault memory that cannot be cleared. Then the airbags and seatbelt pretensioners may fail to trigger in an emergency.

Typical signs are:

• airbag warning light that lights up permanently or intermittently
• fault message in the instrument cluster
• diagnostic tool gets no connection to the control unit
• fault memory cannot be cleared

As soon as one of these signs occurs, you should have the system checked.

Compare the part number on the label of the removed unit with this page; this only ensures that it is the correct unit. Also have the fault memory read out beforehand, because only this result shows whether the control unit itself is defective or whether a plug or a cable is the cause.

For the same vehicles, we also repair control units with the part numbers 13 283 819 HB, 13256903, 13256905 CC, 13283819, 13379528 HU, 13379529.

How does the repair of the 13379528 work?

First have the fault memory read out and enclose the log, then disconnect the battery and only afterwards remove the control unit. Then create a repair order online and send the well-packed unit in. Airbag24 checks it on the test bench, replaces defective components, erases crash data and carries out a function test, after which your own unit is returned.

This sequence is mandatory for safety reasons. The log helps Airbag24 to assess the condition of the unit.

At Airbag24 processing usually takes 3–4 working days. During this time the unit is checked, repaired and tested. 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 13379528 get to Airbag24?

You send the unit as a parcel or book a UPS collection for an extra charge. After the repair Airbag24 returns it to you by UPS; you place the printed repair order in the parcel.

Pack the control unit shock-resistant, for example in padded cardboard, so that it arrives undamaged.
