Airbag control unit with part number 1356789080

What does the airbag control unit 1356789080 do?

The unit 1356789080 is the airbag system control unit for Fiat and Opel. It reads the signals from the crash sensors, decides within milliseconds in an accident on triggering airbags and seatbelt pretensioners, and keeps the system under control. After an accident it stores crash data and locks itself.

It shows abnormalities via the airbag warning light in the instrument cluster.

Why does the control unit 1356789080 fail?

Most often the cause is crash data that the unit has stored after an accident, even though no airbag has triggered. An ordinary diagnostic tool cannot remove it; Airbag24 deletes it during the repair. Other possibilities are ageing electronics, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

Voltage spikes occur, for example, when the battery is weak or when a vehicle starts with a jump start.

Without testing, it is not possible to say which of these possibilities applies in the specific case.

How can you tell that the 1356789080 is defective?

A defect shows through the airbag warning light in the instrument cluster, which either burns constantly or only lights up now and then. An error message may also appear in the instrument cluster, and the diagnostic tool finds no connection to the control unit. In such a case, airbags and seatbelt pretensioners may possibly fail to deploy in an emergency.

If the fault memory cannot be cleared, that is another sign of a fault.
