Description And Operation: Operation
The ORC receives an ignition-operated power supply (INT) from the circuit protected by a fuse in the BCM.
The front impact sensors or ECS detect light impacts and communicates them to the ORC. When a frontal impact is detected according to the control logic, to the data from these sensors and the two sensors incorporated into the ORC, the ORC sends control signals for deploying the front airbags and tensioners to the following system components:
- DAB, through the clockspring in the Steering Column Control Module (SCCM) on the steering wheel
- PAB
- driver side front seat belt tensioners
- passenger side front seat belt tensioners
The side pressure and acceleration impact sensors send signals to the ORC. When, on the basis of the control logic, a side impact of a certain severity is detected, the ORC sends signals for the deploying the airbags to the following system components:
- driver side front seat airbag
- passenger side front seat airbag
- driver side curtain airbag
- passenger side curtain airbag
In case of collisions of a certain severity, the ORC sends the control signals to fire the pyrotechnic fuse.
The switches on the driver seat belt and the passenger seat belt are connected to the ORC.
The ODS interrupts the seat belt signal if there is no passenger.
The ORC is connected to the BCM and to the Instrument Panel Cluster (IPC).
When the system self-diagnosis function detects a fault or an impact is recorded, the ORC sends a signal, via the CAN, to activate the "airbag" warning light located in the IPC. Similarly, it switches on the "seat belt not fastened" warning light if the seat belts are not fastened.
The passenger airbag indicator light is arranged on the overhead console: the ON/OFF signals are sent to the ORC.
