Airbag control unit with part number 13227919

What does the airbag control unit 13227919 do?

The airbag control unit 13227919 is the central control unit of the restraint system (SRS) of Opel. It evaluates the signals from the crash sensors, determines within milliseconds in an accident which airbags and seatbelt pretensioners are triggered, and monitors the system continuously.

Faults are shown via the airbag warning light in the instrument cluster. In everyday driving, this is how you learn that something is wrong with the restraint system.

After an accident the control unit stores crash data and locks itself. The sensors are evaluated in the background, without you having to intervene.

Why does the control unit 13227919 fail?

Stored crash data is the most common cause, even when no airbag has deployed. Other possible causes are ageing electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

A normal diagnostic tool cannot erase crash data. It therefore stays in the control unit, and the unit shows this condition when it is read out.

The other causes concern the unit itself and its connections. An inspection shows which of them applies in each individual case.

How can you tell that the 13227919 is defective?

The airbag warning light in the instrument cluster lights up constantly or only intermittently. A fault message in the instrument cluster and a diagnostic tool with no connection to the control unit are also signs, as is a fault memory that cannot be cleared. In that case, airbags and seatbelt pretensioners may not deploy in an emergency.

The light indicates a detected fault, and lighting up only intermittently changes nothing about that. Please act on this warning.

A missing connection to the diagnostic tool can point to the control unit, but it does not have to. The readout shows what the cause is.

First compare the part number on the label of the removed unit with this page. This only confirms that you have the correct unit. Then have the fault memory read out. Only this result shows whether the control unit is defective or a plug or cable is the cause.

For the same vehicles, we also repair control units with the part numbers 1232168, 13 181 977 DU, 13 188 857, 13 249 347 ST, 13 251 080 EC, 13 251 081.

How does the repair of the 13227919 work?

First have the fault memory read out and attach the log to the unit. Then disconnect the battery before removing the control unit. Next, create a repair order online and send the unit in, well packed.

The order matters for safety and is therefore binding. Removal only begins once the battery has been disconnected.

At Airbag24 the unit is checked on the test bench, defective components are replaced and stored crash data is erased. A function test follows, and then your own unit goes back to you. Testing, repairing and checking usually take 3–4 working days at Airbag24.

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.
