Universal Asynchronous Receiver-Transmitter (UART) Based Protocol (UBP) Communications Network
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 UBP communications network is a single circuit communications network, circuit 693 (OG). The UBP communications network is a communications network used for the electronic automatic temperature control (EATC) module, the instrument cluster and the vehicle security module communications. The UBP communications network does not function if the circuit is shorted to ground or voltage. The UBP communications network is different from the ISO 9141 communications network in that it allows intermodule communication.
