Airbag control unit with part number 13518659

What does the airbag control unit 13518659 do?

As the SRS control unit, the airbag control unit 13518659 in Opel vehicles ensures that airbags and seatbelt pretensioners fire at the right moment. It reads the crash sensors, makes a decision within milliseconds in a crash, and monitors the entire system continuously.

It communicates faults via the airbag warning light. After a crash it stores crash data and locks itself.

Only the repair lifts this lock.

Why does the control unit 13518659 fail?

The most common cause is stored crash data, which remains in the unit after a crash even if no airbag has deployed and cannot be erased with a normal diagnostic tool. Other causes are aged components, cold solder joints, moisture and corrosion, and voltage spikes.

Possible triggers in detail:

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

During the repair at Airbag24, the workshop erases the crash data.

How can you tell that the 13518659 is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently as soon as there is a fault in the control unit. An error message also appears in the instrument cluster.

If the diagnostic tool does not establish a connection to the control unit and the fault memory cannot be cleared, there is a problem that must be taken seriously.

In an emergency, airbags and seatbelt pretensioners could then fail to deploy, so an early check provides safety.
