Principles of Operation: Notes
WARNING: This page is about a different car, the 2006 Ford Pickup, 2006 Ford F550 Super Duty, 2006 Ford F450 Super Duty, and 2006 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
The vehicle has 3 module communications networks:
- controller area network (CAN)
- international standards organization (ISO) 9141 communications network
- universal asynchronous receiver-transmitter (UART) based protocol (UBP) communications network
The diagnostic tool connects to the communications networks through the data link connector (DLC). The DLC allows a diagnostic tool access to diagnose and test the vehicle systems of any module on the communications networks.
