Communications Network: Notes
WARNING: This page is about a different car, the 2009 Mercury Grand Marquis and 2009 Ford Crown Victoria. However, it is still accessible from the selected car via links, so may be relevant.
The 3 module communication networks are:
- High speed controller area network (HS-CAN)
- International Standards Organization 9141 (ISO)
- Standard corporate protocol (SCP)
Information is sent to and from individual control modules that each control specific functions. All 3 networks are connected to the data link connector (DLC). The DLC can be found under the instrument panel between the steering column and the audio unit. The ISO network is for diagnostic use only while the HS-CAN and SCP network allow multiple modules to communicate (transfer data) with each other on a common network.
