Airbag control unit with part number 13517431

What does the airbag control unit 13517431 do?

The airbag control unit 13517431 is the control centre of the restraint system (SRS) for vehicles from Opel. It evaluates the crash sensors, determines in an accident which airbags and seatbelt pretensioners are triggered, and monitors the system continuously. It indicates faults via the airbag warning light.

The decision in a crash is made within milliseconds. For this, the unit evaluates the sensor signals and records faults in the fault memory.

After an accident the control unit stores crash data and locks itself.

Why does the control unit 13517431 fail?

The most common cause: crash data stored after an accident, even if no airbag has deployed. Other causes are ageing electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

A standard diagnostic tool cannot delete this crash data. The other causes in overview:

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

Which cause applies in an individual case is shown only by the fault memory.

How can you tell that the 13517431 is defective?

A defect shows up as the airbag warning light, which lights up permanently or intermittently, as an error message in the instrument cluster, or as the diagnostic tool not making a connection to the control unit. A fault memory that cannot be cleared is added to these.

Typical signs are:

• airbag warning light lit permanently or intermittently
• error message in the instrument cluster
• diagnostic tool does not get a connection to the control unit
• fault memory cannot be cleared

In an emergency, airbags and seatbelt pretensioners may not trigger in the event of such a defect. Have the system checked promptly.
