1. A method for detecting failure in cables and/or physical layer devices (PHY) linked thereto, of a communications network in a vehicle, the method comprising:
obtaining values for one or more physical layer device (PHY) parameters from one or more cables and/or a PHY linked thereto, of a communications network of a vehicle;
analyzing the obtained values to determine a range of operational values for each of the one or more PHY parameters,
the operational values comprising, for each of the one or more PHY parameters, predetermined acceptable values for performance of a cable and/or a PHY linked thereto, and
the range of operational values, for each of the PHY parameters, being based on analyzing a history of the obtained values for each of the PHY parameters from the one or more cables and/or the PHY linked thereto;
detecting values for the one or more of the PHY parameters from the cable and/or the PHY linked thereto of a communications network of a vehicle during an operational time period when the vehicle is operating;
applying, to the detected values, a computer trained model that analyzes changes in the detected values within the operational time period against the range of operational values, for the respective PHY parameter, to determine that the cable and/or the PHY linked thereto may fail within a predetermined time period; and
providing an indication, based on detected changes in the values, that the cable and/or the PHY linked thereto may fail within the predetermined time period.
