Airbag control unit with part number 13575449

What does the airbag control unit 13575449 do?

The 13575449 forms the central control unit of the SRS system for Opel. It processes the readings from the crash sensors, determines the airbags and seatbelt pretensioners to be triggered within milliseconds of an impact, and monitors the entire system continuously. After an accident it stores crash data and locks itself.

A detected fault appears via the airbag warning light in the instrument cluster. Monitoring runs in the background without interruption.

Because very little time is available in an emergency, the electronics must have no gaps.

Why does the control unit 13575449 fail?

The most common cause is crash data remaining in memory after an accident, even if no airbag fired; an ordinary diagnostic tool cannot remove it. Aged components, cold solder joints, moisture and corrosion at plugs, and voltage spikes are also to be considered.

In detail these include:

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

Crash data remains the most common cause, because it is directly connected with an accident.

How can you tell that the 13575449 is defective?

A defect shows through the airbag warning light, which lights up permanently or intermittently, through a fault message in the instrument cluster, through a missing connection of the diagnostic tool to the control unit, or through a fault memory that cannot be cleared. In this case airbags and seatbelt pretensioners may fail to trigger in an emergency.

As soon as the warning light comes on, have the fault memory read out, because the light indicates the fault as soon as the system detects it.

A message may disappear after a short time. The fault memory nevertheless records the event.
