Airbag control unit with part number 13202857

What does the airbag control unit 13202857 do?

The airbag control unit 13202857 takes over the evaluation of the crash sensors within the restraint system (SRS) of Opel. In an emergency, it decides within a few milliseconds which airbags and seatbelt pretensioners are triggered, and monitors the entire system.

If the electronics detect a fault, they store it and show the malfunction via the airbag warning light in the instrument cluster.

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

Why does the control unit 13202857 fail?

Crash data from an accident are the most common cause with the 13202857: they remain stored even if no airbag has triggered, and an ordinary diagnostic tool cannot erase them. In addition, ageing components, cold solder joints, moisture, corrosion at plug connections and voltage spikes can be the cause.

Stored crash data cannot be removed with an ordinary reading device. A normal reading therefore does not help, only the repair does.

Electronic components age, solder joints can go cold, and moisture or corrosion disturb the signal paths at the plugs. Voltage spikes, for example from a weak battery or a jump start, additionally stress the circuit.

How can you tell that the 13202857 is defective?

The airbag warning light in the instrument cluster indicates the defect at the 13202857, either permanently or intermittently. Fault messages in the instrument cluster, no connection between the diagnostic tool and the control unit, and a fault memory that cannot be cleared are added.

In an emergency, airbags and seatbelt pretensioners may not trigger in the case of such a defect. The light is therefore a signal that must be investigated promptly.

The light alone does not say what the cause is. That requires reading out the fault memory and checking the unit.

Comparing the part number on the label of the removed unit with this page only ensures that you have the right unit. Whether the control unit is defective or a plug or cable is the cause is decided by the fault memory read out beforehand.

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 13202857 work?

Have the fault memory read out first and enclose the log, then disconnect the battery and only then remove the control unit 13202857. Then create a repair order online and send the well-packed unit in.

At Airbag24 the unit is examined on the test bench, defective components are replaced, crash data are erased and a function test is carried out. Processing at Airbag24 usually takes 3–4 working days; this time relates to checking, repairing and testing only.
