Airbag control unit with part number 13251080

What does the airbag control unit 13251080 do?

The airbag control unit 13251080 manages the restraint system (SRS) for Opel and is its central control unit. It evaluates the crash sensors, decides in a crash within milliseconds on the triggering of airbags and seatbelt pretensioners, and monitors the system continuously.

The unit stores faults in the fault memory and shows them via the airbag warning light in the instrument cluster.

After a crash, it records crash data and locks itself. Only the repair lifts this lock.

Why does the control unit 13251080 fail?

Crash data from an accident is the most common cause, even if no airbag has deployed; a normal diagnostic tool cannot erase it. Other causes are aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes, for example from a weak battery or jump-starting.

Airbag24 removes the crash data during the repair.

Whether any of the other causes is involved is shown by the check. This cannot be judged from the outside.

How can you tell that the 13251080 is defective?

A defect in the 13251080 shows up in the airbag warning light, in fault messages in the instrument cluster, in a lack of connection to the diagnostic tool, and in a fault memory that cannot be cleared.

• Warning light in the instrument cluster lights up permanently
• Warning light lights up only intermittently
• Diagnostic tool receives no connection
• Fault memory cannot be cleared

With these signs, airbags and seatbelt pretensioners may possibly fail to trigger in an emergency. The warning light is therefore a sign you should take seriously.
