Airbag control unit with part number 13187528

What does the airbag control unit 13187528 do?

The airbag control unit 13187528 controls the restraint system (SRS) in the Opel vehicle. It reads the sensor signals, determines within milliseconds in a crash the triggering of airbags and seatbelt pretensioners, and checks the system during operation.

If a fault occurs in the system, the control unit indicates it via the airbag warning light in the instrument cluster. At the same time it keeps the fault information in memory so that a workshop can read it out.

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

Why does the control unit 13187528 fail?

The most common cause is stored crash data from an earlier accident, even if no airbag has deployed. Other causes come from the electronics and the connections, which can have a creeping effect.

Crash data cannot be removed with a usual diagnostic tool. It therefore stays in the unit until Airbag24 erases it during the repair.

The other causes at a glance:

• ageing electronic components
• cold solder joints on the circuit board
• moisture and corrosion at plug connectors
• voltage spikes, for example from a weak battery or a jump start

How can you tell that the 13187528 is defective?

Typical signs are the airbag warning light, which stays on permanently or intermittently, an error message in the instrument cluster, and a diagnostic tool without a connection to the control unit. If the fault memory cannot be cleared, that is also an indication. In an emergency, airbags and seatbelt pretensioners may not be able to deploy.

Pay particular attention to the following signs:

• airbag warning light in the instrument cluster, permanently or intermittently
• error message in the instrument cluster
• no connection between diagnostic tool and control unit
• fault memory that cannot be cleared

If the system detects a fault, the restraint system may be restricted. A check will establish whether the control unit is affected.

Comparing the part number on the label with this page only ensures that it is the right unit, nothing more. Also have the fault memory read out. Only this result shows whether the control unit is defective or whether a plug or 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 13187528 work?

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 in the well-packed unit.

These steps follow a fixed order, because the safety of the system depends on it. The fault memory is secured before removal, and the battery is disconnected before removal.

At Airbag24 the unit is then checked on the test bench, defective components are repaired, the crash data erased and a function test carried out. Processing usually takes 3–4 working days, after which your own unit goes back to you.

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 13187528 get to Airbag24?

The unit reaches Airbag24 as a parcel, or you book a UPS collection for an extra charge. The return after the repair is made by UPS.

The printed repair order belongs in the parcel. Pack the control unit shockproof before shipping it.
