1. A method comprising:
measuring a resistance of a wire in a motor vehicle at a certain time instance to obtain measurement data for the resistance of the wire, wherein the wire is connected in series with an adjustable wire protector configured with a first set of trip data, wherein the wire is coupled to a power source, wherein the adjustable wire protector is further configured to disconnect the wire from the power source when a current through the wire reaches a predefined current threshold, and wherein the predefined current threshold is set to a first current level of the first set of trip data when the adjustable wire protector is configured with the first set of trip data;
comparing the measurement data for the resistance of the wire with comparative value data held in a data storage;
determining whether the wire fails an integrity check based on the comparing of the measurement data for the resistance of the wire with the comparative value data;
determining, in response to a determination that the wire failed the integrity check, a second set of trip data based on the comparing of measurement data for the resistance of the wire; and
setting the adjustable wire protector using the second set of trip data, wherein setting the adjustable wire protector using the second set of trip data comprises reducing the predefined current threshold to a second current level of the second set of trip data and wherein the second current level is less than the first current level.
