Airbag control unit with part number 13203263

What does the airbag control unit 13203263 do?

The airbag control unit 13203263 controls the restraint system (SRS) of Opel. It evaluates the crash sensors and decides in an accident, within milliseconds, which airbags and seatbelt pretensioners are triggered.

It also checks the components continuously and shows faults via the airbag warning light in the instrument cluster.

After an accident it stores crash data and then locks itself.

Why does the control unit 13203263 fail?

The most common cause at the 13203263 is crash data stored after an accident, even if no airbag has triggered. Other causes are aged electronic components, cold solder joints, moisture and corrosion on plug connectors, and voltage spikes.

• Aged electronic components
• Cold solder joints
• Moisture and corrosion on plug connectors
• Voltage spikes, for example from a weak battery or a jump start

A normal diagnostic tool cannot erase the crash data. Airbag24 erases it during the repair.

How can you tell that the 13203263 is defective?

On the 13203263, an airbag warning light in the instrument cluster indicates a fault when it lights up permanently or intermittently. A fault message in the instrument cluster, a missing contact between the diagnostic tool and the control unit, or a fault memory that cannot be cleared also count as signs.

As long as this is the case, airbags and seatbelt pretensioners may not trigger in an emergency.

The warning light is therefore a clear prompt to have it checked.
