Airbag control unit with part number 13587452

What does the airbag control unit 13587452 do?

The airbag control unit 13587452 coordinates the restraint system (SRS) of Opel. It receives the reports from the crash sensors, calculates in a crash within milliseconds which airbags and seatbelt pretensioners fire, and indicates faults via the airbag warning light.

During operation, the unit checks the entire system constantly for irregularities. If it finds one, it records an entry in the fault memory, which a diagnostic tool can read.

In an accident, the control unit stores crash data and then locks itself. It thus also serves as the memory for accident data.

Why does the control unit 13587452 fail?

Stored crash data from an accident is the most common cause, even without a triggered airbag. A normal diagnostic tool does not erase it. Further triggers are aged components, cold solder joints, moisture and corrosion on plug connections, and voltage spikes.

• Aged electronic components that lose performance
• Cold solder joints with a poor connection
• Moisture and corrosion on plug connections
• Voltage spikes, for example from a weak battery or jump-starting

The list summarises the possibilities. Which of them applies in an individual case is only determined by an examination of the unit.

How can you tell that the 13587452 is defective?

The defect shows up as an airbag warning light that lights up permanently or intermittently, and as messages in the instrument cluster. In addition, the diagnostic tool fails to connect to the control unit, and the fault memory cannot be cleared. In an emergency, the airbags and seatbelt pretensioners may then possibly not fire.

• Airbag warning light in the instrument cluster, permanently or intermittently
• Error message in the instrument cluster
• Diagnostic tool without connection to the control unit
• Fault memory that cannot be cleared

The warning light belongs to the safety function of the vehicle and shows when the system is not ready for operation.
