This safety-relevant component is usually located under the center console in the Opel Vectra C, directly below the handbrake lever. It is responsible for receiving signals from the vehicle's crash and acceleration sensors.
The control unit decides in real time whether and which airbags need to be deployed in the event of an accident. After an accident, it stores important crash data needed for system diagnostics and recovery.
Why is the Opel Vectra C airbag control unit defective?
Your Opel Vectra C airbag control unit often malfunctions because it develops internal component errors or stores crash data after an accident that triggers a malfunction.
