Most CJD applications that I have come across have the necessary CAN data on the CAN C Bus. Are you saying that Jeep has switched over to a FD CAN Bus system that uses a faster bus speed with 64 bytes of data rather than 8 bytes at 500kbps? If so, this is the first I have heard about the change.
Thanks

Here's a description out of the service manual
These CAN bus networks provide on-board communication between all of the ECUs that are connected to them. The CAN-C (Chassis), CAN-FD (Flex-Data), and Automotive Ethernet networks are the faster of the CAN systems providing near real-time communication (500 Kbps to 1Gbps). The CAN-IHS (Interior High Speed) system, while slower (125 Kbps) is used for communications between less critical ECUs. These networks comprise the electronics architecture known as Atlantis.
