Airbag control unit with part number 24439953

What does the airbag control unit 24439953 do?

The airbag control unit 24439953 controls the restraint system (SRS) for Opel. The signals from the crash sensors converge there; in an accident the unit decides within milliseconds which airbags and seatbelt pretensioners fire. It monitors the state of the system continuously and indicates faults via the airbag warning light.

After an accident, it stores crash data and locks itself. Only a repair ends this lock.

During operation it stores detected faults in the fault memory.

Why does the control unit 24439953 fail?

The most common cause is stored crash data created after an accident, even if no airbag was deployed. Ageing electronic components, cold solder joints, moisture and corrosion on plug connections, and voltage spikes are also possible causes.

Crash data cannot be removed with a standard diagnostic tool. Airbag24 removes it during the repair, so the unit then works without these entries.

The testing on the test bench determines the other triggers.

How can you tell that the 24439953 is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently when something is wrong. Fault messages in the instrument cluster, a missing connection to the diagnostic tool and a fault memory that cannot be cleared are also signs. Airbags and seatbelt pretensioners may then not deploy in an emergency.

In everyday use this light is quickly noticed, and it requires a check even if the vehicle appears to be driving normally.

The fault memory shows which fault is stored.
