Airbag control unit with part number 13137905

What does the airbag control unit 13137905 do?

The airbag control unit 13137905 works as the control unit in the restraint system (SRS) of Opel. It evaluates the signals from the crash sensors, determines in an emergency within milliseconds which airbags and seatbelt pretensioners trigger, and checks the system continuously. After an accident it stores crash data and locks itself.

If a fault is detected, the airbag warning light in the instrument cluster lights up. The fault is thus made visible before anyone starts a diagnosis.

Why does the control unit 13137905 fail?

Stored crash data is the most common reason, even if no airbag has triggered; a normal diagnostic tool does not delete it. Other causes are ageing electronic components, cold solder joints, moisture and corrosion, and voltage spikes at the control unit 13137905.

Ageing electronic components and cold solder joints can cause a fault on their own. Moisture and corrosion attack the plug connections through which the control unit is connected to sensors and airbags.

Voltage spikes arise, for example, from a weak battery or when connecting jump leads, and additionally stress the electronics. Which cause is actually present is only shown by the check.

How can you tell that the 13137905 is defective?

The airbag warning light lights up permanently or intermittently, an error message may appear in the instrument cluster, the diagnostic tool cannot find the control unit 13137905, and the fault memory cannot be cleared.

The warning light is a direct indication of a fault detected in the restraint system. Even if it only comes on now and then, it is a reason to have the system examined.

In an emergency, airbags and seatbelt pretensioners may then fail to trigger.
