Theory Of Operation

WARNING: This page is about a different car, the 2014 Fiat 500e. However, it is still accessible from the selected car via links, so may be relevant.

The vehicle communications network includes a fault tolerant CAN-B bus of which the Occupant Restraint Controller (ORC) module is part of, and a non-fault tolerant CAN-C bus. The CAN-B bus is used for communication between body and interior modules at 50 kbps. The CAN-B-bus uses a star topology, with all the control modules connected to the BCM as the central hub.
