N2 - This work presents a new approach to evaluate vehicle energy path's 'state of health'. In order to ensure the availability of safety-relevant functions, system paths are either designed sufficiently robust or redundant. In contrast to these hardware-based approaches, a reliable diagnosis concept offers a cost-effective and space-saving alternative by monitoring an energy path's 'state of health' and taking appropriate measures to prevent an imminent failure. Contact degradations represent a previously unmonitored challenge to electrical connection systems. Due to the requirement for a detachable connection, these occur, particularly on connectors. Using the proposed procedure, a connector's diagnosis corridor can be experimentally determined, enabling a predictive diagnosis.
