Airbag control unit with part number 13191825

What does the airbag control unit 13191825 do?

The airbag control unit 13191825 coordinates the restraint system (SRS) of Opel. It evaluates the data from the crash sensors, decides in a crash within milliseconds whether airbags and seatbelt pretensioners are triggered, and monitors the system continuously. After an accident, it stores crash data and locks itself.

The unit checks without interruption whether all connected components are working. If it finds a deviation, it writes the fault into the memory and displays it.

The lock after an accident remains in place until the repair lifts it.

Why does the control unit 13191825 fail?

The most common cause is stored crash data after an accident, even without a triggered airbag; a normal diagnostic tool does not delete it. In addition, there are aged components, cold solder joints, corrosion at plugs and voltage spikes.

Further causes are possible:

• aged electronic components
• cold solder joints
• moisture and corrosion at plug connections
• voltage spikes, for example from a weak battery or jump-starting

Which of these points applies is shown by the examination. Airbag24 removes the crash data during the repair.

How can you tell that the 13191825 is defective?

A defect shows up as an airbag warning light that stays on permanently or intermittently, as a fault message in the instrument cluster, as a missing connection to the diagnostic tool and as a fault memory that cannot be emptied.

• Airbag warning light in the instrument cluster permanently or intermittently on
• Fault message in the instrument cluster
• Diagnostic tool does not find the control unit
• Fault memory cannot be cleared

In an emergency, airbags and seatbelt pretensioners may then fail to trigger. With these signs, the system should be checked.
