A communication interface that facilitates communications over powerlines between a trailer and a vehicle. The communication interface includes a housing having first contact and a second contact accessible from an exterior of the housing. The first contact is electrically coupled to the second contact via a powerline that connects an electrical system of the vehicle with an electrical system of the trailer. The communication interface includes a powerline communication controller having a first set of terminals coupled to a first connector and a second set of terminals coupled to the powerline. The powerline communication controller is configured to receive a first signal from a device of the trailer that indicates a condition regarding a defined region of the trailer. The powerline communication controller is configured to generate, based on the first signal, a second signal representative of the condition, and introduce the second signal onto the first power signal.

Aspects of the present invention are directed at securely calculating and storing odometer data associated with a vehicle. In accordance with one embodiment, a method is provided that checks the integrity of odometer data being received from a vehicle's engine. More specifically, the method includes receiving a first and second engine odometer values for an engine. Then, these odometer values are compared to determine whether data indicative of tampering was received. In this regard, if data indicative of tampering was received, aspects of the present invention adjust the official vehicle odometer value to account for the tampering.
