Airbag control unit with part number 24416701

What does the airbag control unit 24416701 do?

The airbag control unit 24416701 is the central control unit of the restraint system for Opel. It evaluates sensor signals, determines in a crash within milliseconds which airbags and seatbelt pretensioners to trigger, and monitors the system continuously. It reports irregularities via the airbag warning light.

The housing also carries the manufacturer number Continental 5WK42975. This information is an additional marking and does not replace the part number on this page.

After an accident, the unit stores crash data and locks itself. The lock is only lifted by the repair.

Why does the control unit 24416701 fail?

Stored crash data is the most common cause, even if no airbag has deployed. Other causes are aged components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

Crash data remains stored in the control unit until Airbag24 erases it during the repair. A normal diagnostic tool cannot remove it.

Voltage spikes occur, for example, with a weak battery or a jump start. The other causes concern the electronics and their connections, which can age or become damp over time.

How can you tell that the 24416701 is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently. The instrument cluster also shows a fault message, the diagnostic tool finds no connection to the control unit, and the fault memory cannot be cleared.

While the fault persists, airbags and seatbelt pretensioners may not deploy in an emergency. The warning light is the indication through which the defect becomes visible.

Which component is affected, however, the light does not show. For that, the fault memory needs to be read out.
