Chrysler has started using a Controller Area Network ( CAN ) Bus for intercommunication between most every system in at least 6 vehicles. These vehicles are: 2005+ Chrysler 300, Dodge Magnum, Dodge Charger ( All LX line vehicles ), 2004+ Dodge Dakota, 2006+ Dodge Ram, and the 2005+ Jeep Grand Cherokee.

There are 3 separate CAN buses in these vehicles.

-[CAN-C] Engine / Critical systems CAN Bus ( Engine, Transmission, AntiLock breaks, ESP, etc.. )

-[CAN-B] Interior Comfort CAN Bus ( Climate Control, Car Audio system, Dash cluster, EVIC, etc.. )

-[diagnostic CAN-C] Diagnostic CAN Bus ( Has the capability of pulling service codes from the other two buses, but not directly connected to either )

This project is intending on mapping the Interior CAN bus [CAN-B] to allow for after market modifications to take advantage of the enhanced capabilities in these awesome vehicles.
