Airbag control unit with part number 13583433

What does the airbag control unit 13583433 do?

The airbag control unit 13583433 evaluates the signals from the crash sensors for Opel. In an accident, it decides within milliseconds which airbags and seatbelt pretensioners are triggered, and it monitors the restraint system continuously. After an accident, it stores crash data and locks itself.

The control unit reports faults to the driver via the airbag warning light in the instrument cluster.

Seatbelt pretensioners are also controlled by this unit, so a failure affects the whole system.

Why does the control unit 13583433 fail?

Above all, crash data stored after an accident leads to failure, even if no airbag has deployed. A standard diagnostic tool cannot erase them. In addition, aged components, cold solder joints, moisture at plug connections and voltage spikes come into consideration. Airbag24 erases the crash data during the repair.

The unit records crash data as soon as it registers an accident. Important: the entry is made regardless of whether the airbag has deployed.

Beyond that, the electronics themselves and their connections play a role. Aged components and cold solder joints can disturb the function, and moisture and corrosion at plugs degrade the contact. Voltage spikes arise, for example, with a weak battery or a jump start, and they stress the components.

How can you tell that the 13583433 is defective?

A warning shows up as the airbag warning light in the instrument cluster, which lights up permanently or intermittently when there is a defect in the 13583433. A fault message, connection problems and a fault memory that cannot be cleared are added. In an emergency, airbags and seatbelt pretensioners may then fail to deploy.

These signs occur individually:

• airbag warning light on permanently or intermittently
• fault message in the instrument cluster
• diagnostic tool without connection to the control unit
• fault memory cannot be cleared

Such warnings deserve a prompt check, because they affect the restraint system.
