Airbag control unit with part number 13159975

What does the airbag control unit 13159975 do?

The airbag control unit 13159975 controls the triggering of the restraint systems in Opel. It processes the signals from the crash sensors, decides in an accident on airbags and seatbelt pretensioners, and monitors the system continuously.

In addition, the manufacturer number Continental 5WK43469 is printed on the housing, which can be used to match the unit when it is removed.

If the system detects a fault, the airbag warning light in the instrument cluster lights up. After an accident, the control unit stores crash data and locks itself.

Why does the control unit 13159975 fail?

The most common cause is stored crash data after an accident, even if no airbag has deployed; a normal diagnostic tool cannot erase them. Other causes include ageing components, cold solder joints, moisture, corrosion and voltage spikes.

• Ageing electronic components
• Cold solder joints
• Moisture and corrosion at plug connections
• Voltage spikes from a weak battery or a jump start

Airbag24 removes stored crash data as part of the repair. Which of the other causes applies becomes apparent only when the unit is examined.

How can you tell that the 13159975 is defective?

On the 13159975, you recognise a defect by the airbag warning light in the instrument cluster lighting up permanently or intermittently. Fault messages and connection problems with the diagnostic tool also occur.

• Airbag warning light lights up permanently or intermittently
• Fault message in the instrument cluster
• Diagnostic tool receives no connection to the control unit
• Fault memory cannot be erased

If that is the case, airbags and seatbelt pretensioners may not trigger in an emergency. Take the warning seriously.

A label comparison is useful because it shows whether the unit is the right one. It does not, however, clarify the cause. Therefore have the fault memory read out beforehand, because it shows whether the control unit is defective or a plug or cable is the cause.
