Airbag control unit with part number 13517433

What does the airbag control unit 13517433 do?

The airbag control unit 13517433 controls the restraint system (SRS) in Opel vehicles. It reads the sensor signals and decides within fractions of a second in a crash which airbags and seatbelt pretensioners fire.

During operation it checks the system continuously. If it detects a fault, the airbag warning light in the instrument cluster comes on.

If an accident occurs, the unit records crash data and locks itself.

Why does the control unit 13517433 fail?

Most often the cause is the control unit 13517433 itself, more precisely crash data that remains in its memory after an accident, even if no airbag was triggered. A standard diagnostic tool does not erase it; Airbag24 removes it during the repair. Aged components, moisture, cold solder joints and voltage spikes can also be possible causes.

Ageing of electronic components, cold solder joints, and moisture and corrosion at plug connections can cause faults. Voltage spikes, for example from a weak battery or a jump start, put additional strain on the electronics.

How can you tell that the 13517433 is defective?

A defect shows itself when the airbag warning light stays on permanently or intermittently, a fault message appears in the instrument cluster, the diagnostic tool cannot reach the control unit, or the fault memory cannot be cleared.

The signs in detail:

• The airbag warning light stays on or only lights up intermittently.
• An error message appears in the instrument cluster.
• The diagnostic tool does not connect to the control unit.
• The fault memory cannot be emptied.

In that case, airbags and seatbelt pretensioners may not trigger in an emergency.
