Airbag control unit with part number 13599790

What does the airbag control unit 13599790 do?

The airbag control unit 13599790 manages the restraint system (SRS) for Opel. It processes the measured values from the crash sensors, decides within milliseconds in an accident whether airbags and seatbelt pretensioners are triggered, and monitors the system permanently. After an accident it stores crash data and locks itself.

If the unit detects a deviation, the airbag warning light in the instrument cluster lights up and the error message is stored.

For the quick decision the control unit needs clean input signals and a stable supply.

Why does the control unit 13599790 fail?

The most common cause is crash data stored in the memory after an accident, even though no airbag fired. Aged components, cold solder joints, damp and rust at plugs, and voltage spikes are also possible. During the repair of the 13599790 Airbag24 erases the crash data.

A standard read-out tool cannot clear this memory, so it stays in place until the repair.

Electronics age and solder joints can go cold; voltage spikes also cause damage when the battery is weak or when the vehicle is started with external power.

How can you tell that the 13599790 is defective?

When the airbag warning light in the instrument cluster is on, that is the most important indication, whether permanently or only intermittently. An error message in the instrument cluster accompanies it, and the diagnostic tool finds no connection to the 13599790. The fault memory also cannot be cleared; in an emergency, airbags and seatbelt pretensioners may fail to trigger.

Especially when the light only comes on intermittently, it makes sense not to ignore it, as the cause would otherwise remain unclear.

An error message alone does not reveal whether the unit or the wiring is affected. A read-out with the diagnostic tool provides clarity here.
