Chrysler’s Onboard BUS diagnostics

Chrysler On-Board Diagnostics with Bill Fulton

Detailed onboard diagnostics of Chrysler’s CAN and non-CAN compliant communications networks on every Chrysler from 1987 to present is covered by Bill Fulton. He starts with the CCD (Chrysler Collision Detection Data Bus) and then covers its replacement — the PCI (Programmable Communication Interface) — and finally, the modern CAN compliant systems.

Additionally, Hobbs covers the unique SCI BUS circuit for the control modules for transmission and powertrain which achieves more precise sensor readings and troubleshooting information. A scan tool is used to show the different kind of information that can be pulled from each communications system from the global and enhanced sides of the OBD port.
