Airbag control unit with part number 13288174

What does the airbag control unit 13288174 do?

The airbag control unit 13288174 coordinates the restraint system (SRS) in the Opel vehicle. It processes the readings from the crash sensors and determines within milliseconds in the event of an accident which airbags and seatbelt pretensioners are triggered. At the same time it checks the system continuously and indicates faults via the airbag warning light.

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

The control unit is therefore the interface between sensors, airbags and the display in the instrument cluster. Without its evaluation, the restraint system cannot react as intended.

Why does the control unit 13288174 fail?

The most common cause with the 13288174 is crash data stored after an accident, even if no airbag has deployed. Other causes include aged components, cold solder joints, moisture and corrosion on plug connections, and voltage spikes.

Crash data cannot be erased with a normal diagnostic tool. At Airbag24 it is erased as part of the repair.

The following causes come into consideration in detail:

• aged electronic components
• cold solder joints on the circuit boards
• moisture and corrosion on plug connections
• voltage spikes, for example from a weak battery or a jump start

Which of these causes is actually present is shown only by reading out the fault memory.

How can you tell that the 13288174 is defective?

A defect in the 13288174 shows itself mainly through the airbag warning light in the instrument cluster. It lights up permanently or intermittently and thus indicates a fault in the restraint system.

The signs in detail:

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

As long as such a fault exists, airbags and seatbelt pretensioners may not be able to trigger in an emergency. Please have the display checked promptly.

Compare the number on the label of the removed unit with this page. This comparison only ensures that you have the correct unit in front of you. Also have the fault memory read out beforehand, because only the result shows whether the control unit 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 13 181 977 DU, 13 188 857, 13 249 347 ST, 13 251 080 EC, 13 251 081, 13 251 084 EH.

How does the repair of the 13288174 work?

For the 13288174, first have the fault memory read out and attach the log, then disconnect the battery and remove the control unit. Then create a repair order online and send the unit in well packed. Processing at Airbag24 usually takes 3–4 working days.

Attach the fault memory log to the unit so that the workshop at Airbag24 knows the findings.

Airbag24 checks the unit on the test bench, replaces defective components and erases the stored crash data. A function test follows, after which your own unit is sent back to you.

The sequence of steps is fixed for safety reasons.

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.
