CAN Module Communication Message Chart

WARNING: This page is about a different car, the 2010 Ford Focus. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: This chart describes the specific HS-CAN  and MS-CAN  messages broadcast by each module, and the module(s) that receive the message.
