Airbag control unit with part number 13246046

What does the airbag control unit 13246046 do?

The airbag control unit 13246046 is the central control unit of the SRS in Opel vehicles. It evaluates the crash sensors, decides in an accident on airbags and seatbelt pretensioners, and monitors the system continuously. It shows faults via the airbag warning light.

The electronics keep working in the background, so that no time is lost in an emergency.

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

Why does the control unit 13246046 fail?

Most often the fault with the 13246046 comes from crash data that remained in the memory after an accident without an airbag having triggered; a standard diagnostic tool cannot remove it. In addition, ageing components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes, for example from a weak battery or a jump start, come into question.

During the repair at Airbag24 the crash data is erased.

The other causes come from the electronics themselves. Solder joints may be cold, components age, and moisture causes plug connections to corrode.

How can you tell that the 13246046 is defective?

As soon as the airbag warning light in the instrument cluster comes on, fault messages appear, or a diagnostic tool gains no access, the 13246046 probably has a defect. In an emergency, airbags and seatbelt pretensioners may then fail to trigger.

The light may stay on permanently or only come on now and then. Either is a sign you should not ignore.

If the fault memory cannot be cleared or the diagnostic tool cannot establish a connection, have it checked as well.

If the part number on the label of your removed unit matches this page, it is the right unit. Whether the control unit itself is defective, however, only the fault memory read out beforehand will show. It shows whether a plug or a cable is the cause, so have it read out before removal.

For the same vehicles, we also repair control units with the part numbers 1232168, 13 262 360 BD, 13 288 173 CF, 13188856, 13241766, 13262360.

How does the repair of the 13246046 work?

First have the fault memory read out and enclose the log, then disconnect the battery and remove the control unit. Create the repair order online, then send the well-packed unit in. Airbag24 checks the unit on the test bench, replaces defective components, erases the crash data and carries out a function test. Processing usually takes 3–4 working days, after which your own unit is returned.

The sequence is fixed for safety reasons. Only once the battery is disconnected is the control unit removed.

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.
