Airbag Control Unit
The control unit is the heart of the airbag system and is installed centrally in the vehicle. It can generally be found in the dashboard area, on the centre tunnel.
It is responsible for the following:
Detecting accidents.
Detecting the signals sent by the sensors in a timely manner.
Triggering the necessary firing circuits in a timely manner.
Providing the power supply to the firing circuits using the capacitor, independently of the vehicle battery.
Running self-diagnostics on the entire system.
Storing faults in the fault memory.
Activating the airbag indicator lamp if the system fails.
Connecting to other control units via the CAN bus.
