Abstract
Methods and systems are provided for detection and analysis of abnormalities in a power line communication network of a vehicle. The vehicle includes various vehicle modules. The power line communication network includes power lines designed to carry electric power to the vehicle modules. Each vehicle module includes a power line communication module that is communicatively coupled to at least one of the power lines. The power line communication modules enable the power lines to communicate communication information to and from the vehicle modules. The power line communication modules can communicate pilot signals over the power line communication network. One or more of the power line communication modules includes a reflectometer module configured to perform reflectometry processing on the pilot signals to determine properties of the power line communication network.
