What does the airbag control unit 90492467 do?

The airbag control unit 90492467 is the central control unit of the restraint system (SRS) on Opel. It evaluates the crash sensors, decides in a crash within milliseconds which airbags and seatbelt pretensioners are triggered, and monitors the system continuously. After an accident it stores crash data and locks itself.

The manufacturer's number Continental 5WK4110 is additionally printed on the housing. The unit shows faults via the airbag warning light in the instrument cluster.

Why does the control unit 90492467 fail?

The most common cause is crash data stored after an accident, even if no airbag has deployed. They cannot be deleted with a normal diagnostic tool. Other possible causes are aged components, cold solder joints, moisture and corrosion, and voltage spikes.

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

How can you tell that the 90492467 is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently, accompanied by an error message in the instrument cluster. The diagnostic tool finds no connection to the control unit, and the fault memory cannot be cleared. Airbags and seatbelt pretensioners may possibly fail to deploy in an emergency.

This light indicates the defect, so the light is the sign you should watch for. A check then clarifies the cause.
